Leaded brass is a type of brass alloy that contains a small percentage of lead, typically ranging from 0.5% to 3%. The addition of lead enhances the alloy's machinability, making it ideal for high-speed machining processes. This brass is often used in applications requiring precise, intricate components, such as plumbing fittings, valves, and fasteners. Its excellent corrosion resistance, ease of manufacturing, and ability to form complex shapes make it a preferred material in industries like automotive, electrical, and marine. Leaded brass also exhibits good tensile strength and durability, ensuring long-lasting performance in various environments.
