H62 brass to zinc as the main element of the copper alloy, with a beautiful yellow, collectively referred to as brass. Binary alloy of copper and zinc that ordinary brass, or a simple brass. More than triple brass called special brass or brass called complex. Less than 36% zinc brass alloy by solid solution, with good cold working properties, such as 30% zinc brass is often used to make shells, commonly known as cartridge brass, or 73 brass. Zinc brass alloy by solid solution between 36 to 42%, of which the most commonly used is a 40% zinc ** brass. In order to improve the performance of ordinary brass, often add other elements, such as aluminum, nickel, manganese, tin, silicon and lead. Aluminum can improve the strength, hardness and corrosion resistance of brass, but the plastic lower, suitable for sea condenser and other corrosion-resistant parts. Tin can improve the the brass strength and corrosion resistance to seawater, it said the Navy brass, as the ship of thermal equipment and propeller. Lead can improve the cutting performance of brass; This cutting brass is often used as watch parts. Brass castings used to make valves and pipe fittings.
