I hope someone can help me.
1. What is the amount of Copper in Brass? As in a full size bed.
2. What other metals make up brass, and what is the amount of each?
3. What is the scientific symbol for Brass, and Copper.
4. Magnets do not stick to brass, why is this?
Thank you,
AE
Red brass contains ~85% copper, as well as ~5% lead, ~5% tin, and ~5% zinc. Copper's symbol is "Cu"; brass, as an alloy and not an element, does not appear on the periodic table. (Lead is Pb, Tin is Sn, and Zinc is Zn).
4. Magnets stick to Iron which is not in Brass.
Iron and many iron alloys are the most commonly encountered magnetic materials. Nickel and cobalt are other fairly common magnetic metals, along with some of their alloys. Some of the stronger magnets that you can buy use rare-earths, such as neodynium.
If you were to measure very carefully, you'd find that magnets are attracted slightly to all the ordinary 'non-magnetic' metals, such as copper, silver etc. However, those forces are quite weak.

It must be as you say Francis; I can't get a magnet to stick to my brass bed.
I did not know brass had so much copper, this pleases me.
Thank you all for your help.

I believe I can speak for the masses and say this pleases us all.
Thanks for your input Gus, it's always welcome. LOL I have my reasons for saying that. *cutie*
Materials are classified as ferromagnetic, paramagnetic, or diamagnetic. The ones we think of as having an affinity for magnets are ferromagnetic. The way in which a material interacts with magents relates to the magnetic properties of its atoms.
A magnet is usually just a ferromagnetic material which has had its atom's dipoles aligned by an external magnetic field.
