C48500
Naval Brass Alloy
Mueller Brass C48500, also known as leaded naval brass, is a wrought copper-zinc-lead-tin alloy. It is a high-zinc brass to which a small amount of tin is added to improve its corrosion resistance and also to impart higher strength. Tin, like arsenic, antimony, and phosphorus, reduces susceptibility to dezincification. Mueller Brass C48500 possesses good hot formability and is fairly well adapted to any hot working process including forging.
