Abstract

MUELLER Alloy 4430 is a copper-zinc-tin alloy. It contains a small addition (nominally 0.06%) of arsenic as inhibiting element to protect the alloy against stress corrosion. It is commonly known as Admiralty Metal. It has a good combination of strength and ductility and good resistance to corrosion. It is used widely for condenser, evaporator and heat-exchanger tubes and associated applications. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Cu-497. Producer or source: Mueller Brass Company.
