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.

ANACONDA Alloy 1870 is a free-cutting high-conductivity copper. It is a deoxidized copper with lead added to impart free-cutting properties. The various and unusual properties of Alloy 1870 make it suitable for many applications in the manufacture of parts machined from rods and for current-carrying studs, nuts and bolts designed for use at normal temperatures. Because it is deoxidized, it is not susceptible to hydrogen embrittlement if heated in a reducing atmosphere. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and shear strength. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Cu-318. Producer or source: Anaconda American Brass Company.

AMSULF is a free-machining copper combining high electrical and thermal conductivities with a machinability rating of 85% of free-cutting brass. (Conventional oxygen-bearing and oxygen-free coppers have ratings of 20%). AMSULF copper offers uniform machinability; in addition, it is resistant to hydrogen embrittlement because it is based on oxygen-free copper. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and shear strength. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Cu-125. Producer or source: Amax Copper Inc.. Originally published February 1963, revised June 1976.

AMTEL is a free-machining copper combining high electrical and thermal conductivities with a machinability rating of 85% of free-cutting brass. (Conventional oxygen-bearing and oxygen-free coppers have ratings of 20%). AMTEL copper offers uniform machinability; in addition, it is resistant to hydrogen embrittlement because it is based on oxygen-free copper. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and shear strength. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Cu-191. Producer or source: Amax Copper Inc.. Originally published September 1968, revised January 1976.

Amphos is a phosphorized oxygen-free copper having free-scaling properties, freedom from hydrogen embrittlement, improved cold workability, and desirable high softening temperature. This datasheet provides information on composition, physical properties, and tensile properties. It also includes information on forming, heat treating, and joining. Filing Code: Cu-135.
