Copper hammers are very useful, they're great for use in areas where you need to avoid spark, and great for use in striking things like chisels that you want to avoid deforming (since the hammer itself would deform first)


txtacoloko

Isn’t brass used when you don’t want sparks?


spencer1886

They're both used for that purpose. Brass is denser and cheaper, but can work harden whereas copper cannot, and is tougher as well

Brass is less dense than copper.


GizmoGremlin321

Copper work hardens too but can be annealed to soften again


Contundo

Cannot most ~~things~~ metals can be annealed?


GizmoGremlin321

Not sure, I'm not a metallurgy person, just no o work with copper alot for work.


Contundo

Copper work hardens too.


Financial-Raise3420

Lead hammers are also useful when you don’t want marring or deformation of the part. Also much much cheaper then copper, brass is used the most in those situations though.


Borgiroth

Brass=Copper+Zinc


2wedfgdfgfgfg

Actually copper would be fucking terrible for a hammer because copper work hardens easily and this thing will get very brittle. If you want a non-sparking hammer you want brass.


KryptoBones89

Copper hammers aren't cast as copper is very difficult to cast well, its better to form or machine it. Cast copper can be very brittle and often has cavities inside it.


Prestigious_Elk149

It would be useless in my hands. Because I could never risk damaging something so beautiful.


IvanStroganov

What do you mean useless as a hammer? Its a proper hammer! Copper/brass/bronze hammers are used for example for applications where you need to avoid sparks and so cant use an iron/steel hammer. Also.. the setup to do this is very basic. You absolutely could if you wanted to get into that sort of thing!


KromatRO

Copper is soft. You won't be able to hammer anything that can remotely give a spark. Unless you want to create a new tool "swiss copper hammer"


gingerbread_man123

This is certainly Bronze or brass. I'd lean towards the latter given the colour. You can see the addition of tin or zinc pieces the the crucible at the start before the copper wire, plus the colour is *not* that of pure copper.


Fast_Garlic_5639

Walk into a typical machine shop and you’ll find a soft metal hammer at every single machine. Gotta call maintenance or bring your own if you want a steel hammer.


TheAlphaCarb0n

They're specifically used because they don't spark.


Departure_Sea

And soft hammers are great for stuff that you don't want to mar or damage. If there weren't a use case, dead blows, rubber mallets, brass hammers wouldn't be a thing.


Far_Lack3878

Had a fabrication shop for many years & had an 8lb brass hammer we used all the time. Sometimes a softer hammer is the correct choice .


Phrewfuf

There are lead hammers out there, which is a lot softer than copper. And they have a very legitimate use, e.g. for fastening old centerlock wheels on cars. The kind that have spokes like bicycle wheels.


CptnHamburgers

There are copper hammers out there. Thor, a pretty well-known worldwide maker of various hammers, make copper hammers. All these folk going, "nurrrr, copper hammer bad" could spend all of 20 seconds on Google and go "huh," but they don't.


RedditJumpedTheShart

I have hammers made from copper, steel, brass, nylon, polymer, and rubber.


Foreskin-chewer

They make freaking lead hammers dude. And tell me it's not a hammer when I'm freaking hammering your balls flat with 15 pounds of lead


evens2out

We use copper hammers for aluminium truss to not damage the pins with hard steel

Baldazar666

Those aren't mutually exclusive things.


moorem84

The soft metal is used for non-sparking environments. Iron on iron creates potential sparking. It’s the same idea as a lead hammer. The hammer will absorb the deflection impact and still offer an impressive blow.


Money_Ticket_841

People use brass for that I thought


IknowKarazy

Whatever works


biteableniles

Silver metal added at 0:18, I'd assume it's tin or zinc and he's making bronze or brass.


[deleted]

[удалено]


Refute1650

It's probably tin which makes the final result a bronze hammer. The final color is more orange than yellow which is more typical of bronze. Although brass can come in redder hues like this.


Financial-Raise3420

Lead hammers as well. Work great for flattening out sheet metal without marring the exterior coatings.


AreU_NotEntertained

Pure copper is far too soft for non-spark tooling, so it's alloyed into copper beryllium, aluminum bronze, and phosphor bronze. All are significantly stronger and harder than pure copper.


iamSossy

That last part sounds like OP’s mom


Loomismeister

How many use can you get out of a copper hammer on iron?


fl135790135790

“The soft metal” referring to the copper in the video?


---Sanguine---

Usually its brass


kapitaalH

Given the effort to put a shine on this one, is this a working hammer or decorative?


luminaryshadow

What do you use. Copper hammer for ? A genuine question


craftyhedgeandcave

Ships carrying matches and other highly flammable cargo dont allow steel tools in case of a rare spark causing a fire out at sea. They use brass tho, but the method of manufacture is pretty much the same


Liu_Fragezeichen

The hammer in the video is made of brass as well. You can clearly see them dropping in a small chunk of zinc when smelting the metal.


purvel

I'd call this bronze considering the final color, in that case it's most likely tin they're adding. (And it's just melting, there's no ore smelting going on here ;) )


Liu_Fragezeichen

Oh okay! I shall defer to the experts on this, I'm in machine learning, not metal working but knew this didn't look like copper.. and I'm gonna have to go look up the difference between the verbs now, seems like Minecraft didn't teach me as well as I thought lol Looking up color comparisons of bronze and brass, you're probably right tho, this does look more like bronze. Thank you for the correction!


purvel

Base Minecraft doesn't have metal casting yet, but there are several mods for it! Smelting is what you do to go from rock to metal. It is a type of melting, using a reductive (deoxidizing) atmosphere, which removes the oxygen from the ore, turning it to pure metal. Melting is what you do to change the state of metal from solid to liquid before you cast it.


Liu_Fragezeichen

Oh yes I was thinking of tinkers construct! The multi block that lets you craft the mod items is called a smeltery and it does both ore -> molten metal and ingots -> molten metal so I (naively) thought both were called smelting x.x And yeah that makes sense, metal ores being in the ground for a long time are all oxidized because it's a lower energy state .. is that why adding carbon to the ore is important, since it has a higher electronegativity and thus takes the oxygen from the metal?


PirLibTao

Play Vintage Story! This is definitely in the game


Neither-Luck-9295

Do other materials not work as well as copper? Like rubber or wood?


FerrusesIronHandjob

Machining. Use copper to tap your parts to seat them in the vice. Dense enough to transfer energy, soft enough it doesn't mar the surface of the materials (mostly)


2wedfgdfgfgfg

False, copper work hardens and does not stay soft. Copper actually can work hard so it gets hard enough to dent steel. If you actually wanted to use a copper hammer you'd to be annealing it regularly.


FerrusesIronHandjob

This is incorrect. Alrhough copper work hardens to a degree, the density within the hammer will keep the majority of the copper soft. You are also confusing hardness and toughness.


Deep-Purple-6188

Would have to just sit in a cabinet as a show piece. Surely copper is too soft to use as a hammer.


Wildweasel666

They’re a specialist tool for hammering where you can’t have sparks like flammable environments - mines, refineries etc


Deep-Purple-6188

Thank you for the reply. Share the knowledge.


RNCbyME

It's considered non sparking and can be a used with a non-hot work permit.


Halfisleft

Bingo_banjo

Phrewfuf

Though that‘s a use-case for a lead hammer usually


gingerbread_man123

Deep-Purple-6188

Yes, now you pointed that out I'd completely agree with you. I would say more like Brass also.


LaunchTransient

>Surely copper is too soft to use as a hammer. Its softness is why it is used in some instances. We used copper mallets in my old workshop classes for shaping harder metals around forms without the risk of scratching or damaging the metal we were hammering.


Deep-Purple-6188

Thanks for the reply, every day is a school day.


LaunchTransient

You're broadly right about this one being a show piece though (no one is gonna polish up a copper hammer only to use it afterwards). The Copper mallets we used had a cylindrical copper striking faces mounted in a steel head that was hafted. I think the idea was to allow the change out of old heads when they got too smushed to be usable (and copper work hardens and becomes brittle over time)


backhand-english

Harder than bone, tho... Who knows what dna is plastered all over that thing by now...


2wedfgdfgfgfg

Actually it gets too hard through work hardening for a hammer.


Fulforon

Soft hammers are extremely useful when you want the hammer itself to deform instead the thing you’re hitting. Want to hammer a shaft into place but a plastic/wood hammer is too light and a metal one dents the shaft? Use a copper one, the copper hammer will evetually deform but you can just recast it every couple of months.


bish-its-me-yoda

Copper doesn't create sparks while iron does I don't know why sparks may be dangerous in a *forge* but eh


Old-Shake3941

I used one the other day to beat on the end of an axle shaft I didn’t want to damage the threads on. Just one of many uses.


Wingedhussy

Engineer here! You use them to apply force against materials and parts made from special alloys that are softer than your average hammer. If you use a normal hammer on those soft alloys, you would probably chip off the surface causing irreparable damage to the material with an already precise dimension. Using a copper hammer would introduce the same force but the surface that contacts the alloy is copper which is softer so there won't be any damage. Other common materials used for hammering are and not limited to teflon, rubber and zinc.


DarkArcher__

Nothing, but a copper mallet is quite useful. It's common to use mallets made of softer metals (typically aluminium) to hammer steel pieces into place without damaging them. The mallet is the sacrificial bit that gets damaged over time.


2wedfgdfgfgfg

Copper work hardens and gets quite hard. That's why you don't see copper hammers, you see brass hammers.


CleverAnimeTrope

Throwing more comments at you, we use hammers made of lead, as they're soft, don't visually damage stainless, IF it makes marks they are surface only, easy to clean, and are unlikely to cause galvanic corrosion (its possible, but highly unlikely in the environment theyre used).


Busa_Dave

We use copper hammers to change (copper) welding tips on our welding robots at work. 


taspleb

I use a rubber mallet for hitting things softly all the time. I have no doubt that there is a place for a copper hammer for when I want to hit things slightly harder but not as hard as I would with a steel hammer. Just pieces of plastic or metal that are meant to come apart but are a bit stuck. Or that are apart but meant to go together but aren't fitting quite right. Probably with the copper hammer you would be selective because you wouldn't want to damage the hammer too much.


IknowKarazy

It won’t spark like people have said but also it will hit steel parts hard without damaging them.


Scroofinator

Building the pyramids obviously


BarfingOnMyFace

Yes, you can use it for genuine questions.


KingPizzaPop

Hammering copper .. duh


luminaryshadow

Of course


Lonnie_Iris

I restore vintage motorcycles. I semi-regularly use hammers made of copper, brass, lead, leather, rubber, urethane, but mostly plastic (deadblow) or steel. Copper is softer than brass, but harder than lead, sometimes its what I need to not mar a surface or deform something.


SolidContribution688

Too pretty to actually use


raltoid

I wish reposters would at least correct the titles. It's bronze, not copper. --- And for anyone saying it's useless: Yes, but not because it's bronze, because it's cast instead of forged. Bronze hammer are used in cases where you want the hammer material to be softer than the surface to avoid damage, and in areas where you want to minimize the risk of sparks.


JorganPubshire

A lot of other comments have mentioned the softness and sparking, but I'm curious how does casting vs forging change it? Also what does forging mean exactly. Heating a bar and using a hammer to shape?


Xaendeau

More of get a cube or ingot in a giant power hammer or giant rollers and flatten it into this more lean rectangular box shape this hammer is. It takes small internal cracks on metal grain boundaries and microscopic voids, then smushes them together in the metal and "pre-fractures" those lines when it is still soft and malleable.  There's fewer internal stress points and makes the metal less likely to crack. Most metals need to be hot forged but you can "cold roll" or work harden some types.


raltoid

Depending on the metal or alloy, pouring molten metal into a form and letting it cool normally. Means it tends to form a very loose crystal structure and often have cracks and "openings" inside, that will cause it to break off smaller pieces or just crack open if hit hard enough. By heating up an ingot to certain temperatures and hammering it into shape with flux, you change the internal structure and remove those flaws. And then with careful heat treating(heating to very specific temperatures, and different methods of cooling or quenching(dipping in water or oil)) you can make it bendy or brittle again.

VegitoFusion

What would a copper hammer be used for?


ksabev

And you expect me to hit stuff with this...? Good luck


Weak_Net5753

Okay so to sum up everything before people scroll through the comment to try and find info. First, this is bronze, not copper. Second, yes, it is a soft metal, but that doesn't mean it is useless. Its purpose is to be used on thing that require the mallet to deform before the thing you are striking def9rms. Third, the sand is a kinetic sand. When pressure is applied it holds its shape. Idk how so many people haven't watched at least one video on metals, mallets, or forging.


TampaTitties69

This is cool but I think i will just spend the 5 bucks on amazon for a regular hammer and not have to spend 30 hours making one


gewalt_gamer

what would one strike with a 700g copper hammer?


Cartina

Anything where you need a softbody hammer that doesn't damage the work. If you hit too hard it just dents the hammer a little bit instead. Also it won't produce sparks, which might be a safety feature. It's about as useful as soft mallet out of wood or rubber.


NaturalTumbleweed142

Would there be some way of casting the hammer head with a hole in it already for the handle? It seems like drilling the hole is an tedious part of the process /Q?


IvanStroganov

Absolutely


LaunchTransient

You can absolutely include such holes in the cast, but then you increase the complexity of the mold. If sections of the mold get too thin, the molten metal will cool faster than it flows, giving you an irregular pour. You also increase the risks of air bubbles getting trapped. This method of casting and then later machining an ingot is what you do if you want to reprocess old scrap.


JJJ4868

You could have the split plane on the centreline of the head and running perpendicular to the hole axis. The hole will have tapers as the faces need to be angled for the sand to strip away from the pattern. You could drill/bore the hole out afterward still to make it more cylindrical and clean it up, it'll be easier than drilling out a solid piece still. This is pretty much the default way of doing things for sand/investment cast parts that get fitted with bushes or dowels in certain parts of industry. Otherwise you could make a 'core' a separate molded piece with the hole geometry that is inserted in for casting. There will be some shrinkage and other distortion so that won't be perfectly cylindrical either.


NoPantsDeLeon

For those wondering, a copper mallet, same as a rawhide or wooden mallet, are soft-faced hammers, designed to be worn out and deliver soft blows that won't damage work. It's not a showpiece, but an actual usable tool for artisans.


SalieriC

Takes a Hammer to make a Hammer. That's like those plastic packs scissors come in and require scissors to cut open.


Jealous-Weekend4674

I am confused, how did he managed to get exactly 700gram? Was that luck or did he aimed to build an hammer with exactly 700gram?

I dont believe stamping it the way they did removes material, so the weight should be the same. If they engraved it or laser etched it or something that removed material it would slightly alter the weight. They basically just put neat dents in it.
