whats heavier? steel, brass or copper

[STANG KILLA SS]

given same size material of course. whats heaviest to lightest?
if i knew how to read a periodic table i could probly figure this out

[Manning]

copper is heaviest, then brass, then steel. Not a huge difference. ~15%

[Daredee]

hope this help

Tungsten is anoher option but need some carefull thinking.
Get small balls and cast them into resin to the desired shape required.

copper 8930kg/cu.m
steel 7850kg/cu.m
brass 8400 - 8700kg/cu.m

You show it is

Excuse me, sir.....I stand corrected. Fixed it.
Guess I misread it.

If you can find steel, and brass on the periodic table, you are a wizard!

Yes, machinable tungsten alloys, like mallory metal, have a density around 17,000 kilogram/cubic meter. This material is used to balance crankshafts.

Actually you can get Tungsten rod stock and cut short lengths. Strap them to an axle for weight (or cast them in resin/lead to a shape in a mold). The resin or lead is what gets machined to do the mounting.

Brass isn't on the periodic table cause it's an alloy of copper(Cu) and zinc(Zn)
Neither is steel either cause it's a form of iron(Fe)

Isnt' copper heavier than iron? Out of all elements of Brass isn't the majority Copper? If I was betting I would bet on Brass! If you dont have a scale. I would download a periodic table. then Google Brass and Steel. You could get a pretty educated guess of the densities.

The question is WHICH ONE IS HEAVIER. Not its not enough to worry about. Heh Heh Heh

Copper is and if I remember its the densest of the 3

Here is a source for tungsten. It is not cheap, but it is already cut into specific weights. They also make a tungsten putty.

They carry this at our local Hobby Lobby.

Just out of curiosity, where does lead fit in as far as weight is concerned?

[Gula]

See if you can get the heaviest and most dense. Depleted uranium. Just don't scratch it or make any dust particles. Should bemable to pick it up at a military surplus store. ROR

Lead is quite a bit heavier. Lead is about 11 and 1/2 grams per cc, copper is just over 8, steel is just under 8.

Depending on the application, Lead would make a great option, as it is dense. easily formable, and cheap.

Gold has two of those attributes as well, but you wouldn't want to use it.....
