Brass pins are often produced from a copper-zinc alloy known as brass, which offers strength, corrosion resistance, and an appealing gold-like appearance. The exact composition varies depending on the required qualities, but standard formulas have 60-70% copper and 30-40% zinc, with tiny amounts of lead or other elements added to increase machinability. Brass is used for pins because metal is both sturdy and easy to form, resistant to rust, and can maintain its finish over time, even in somewhat demanding conditions.
