One of the metals called "red brass" is 85% copper, 5% tin, 5% lead, and 5% zinc. Copper alloy C23000, which is also known as "red brass", contains 84–86% copper, 0.05% each iron and lead, with the balance being zinc. Another such material is gunmetal, from the family of red brasses.
Does brass contain lead?
While our brass does in fact contain approximately 2.5% lead to aid machinability, it is in a solid matrix with the copper and zinc that make up the brass and is entirely encapsulated by a clear coating comprised of acrylics and urethane solids (plastics).
How can you tell if brass is lead free?
The standard lead-free brass fittings are made with marine-grade DZR brass and are currently acceptable under the Safe Drinking Water Act, but will be restricted to non-potable water applications as of 2014. The lead-free fittings are identified by a double groove on the face of the female fitting (see Fig.
Do brass contains nickel?
Did you know that, in addition to zinc and copper, brass can also contain nickel, one of the most serious causes of allergic reactions out there?
Can brass give you lead poisoning?
Lead poisoning is an important hazard in certain types of bronze foundries. Bronze is essentially an alloy of copper and tin, and brass an alloy of copper and zinc. However, this distinction is not always observed in naming alloys. Lead is frequently added to both, sometimes to improve them, sometimes to cheapen them.

Is brass a carcinogen?
Some brass fittings may come with a rather alarming cancer warning. This warning is most likely due to cadmium plating on the brass, and while it does pose a risk, the risk is not severe.
How can I tell if something is bronze or brass?
