Brass is a copper alloy with zinc as the main additive element, known for its attractive yellow color and commonly referred to as brass. Copper-zinc binary alloys are called ordinary brass or simple brass. Brass with more than two elements is called special brass or complex brass. Brass alloys with zinc content below 36% consist of solid solutions and exhibit good cold-working properties. For example, brass with 30% zinc is often used to make brass or 70/30 brass. Brass alloys with zinc content between 36% and 42% consist of α and β solid solutions, with 40% zinc brass being the most commonly used. To improve the properties of ordinary brass, other elements such as aluminum, nickel, manganese, tin, silicon, and lead are often added. Aluminum enhances the strength, hardness, and corrosion resistance of brass but reduces plasticity, making it suitable for marine condenser tubes and other corrosion-resistant parts. Tin improves the strength and seawater corrosion resistance of brass, hence the name naval brass, used in ship thermal equipment and propellers. Lead improves the machinability of brass, and this free-cutting brass is commonly used for clock parts. Brass castings are often used to make valves and pipe fittings.
