Word: Cartridge Brass
Part of Speech: Noun
Definition: Cartridge brass is a type of metal made mostly of copper and zinc. It usually has about 30% zinc in it. This metal is often used to make cartridges (the parts of bullets) or tubing (hollow pipes).
In more technical discussions, you might hear about the properties of cartridge brass, such as its corrosion resistance or how it can be easily shaped (wrought) into different forms.
While "cartridge brass" specifically refers to this metal, "brass" on its own can refer to any brass alloy or can even be used in idiomatic expressions (e.g., "brass tacks" refers to getting down to the basics of a situation).
Understanding cartridge brass is useful if you are interested in firearms, metalworking, or manufacturing.
