Brass is a metal alloy composed primarily of copper and zinc. It is commonly used in musical instruments, decorative items, and plumbing fixtures due to its desirable properties.
The composition of brass typically ranges from 60-80% copper and 20-40% zinc. Small amounts of other metals such as lead, tin, or aluminum may also be added to achieve specific properties.
Properties of Brass
