MUELLER Copper 1220 is a deoxidized copper with high residual phosphorus (nominally 0.02%). It has rather low electrical conductivity but it is not susceptible to embrittlement by hydrogen. Its low electrical conductivity is mainly caused by the phosphorus. It has excellent cold-working characteristics and can be joined by several methods. Among its many applications are air conditioners, gas lines, heater lines, oil-burner and plumbing tubes, dairy tubes and oil lines. 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-495. Producer or source: Mueller Brass Company.
