Copper No. 110, generally known as electrolytic tough pitch copper or ETP, is cathode copper remelted and cast with a controlled oxygen content. It is the most important type of copper commercially available and is used by the electrical industry as wire for electrical conductors, bars for bus-bars and commutators and in forms such as sheet, strip, and plate for many architectural and industrial applications. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and shear strength as well as fatigue. It also includes information on low and high temperature performance, and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Cu-222. Producer or source: Copper and copper alloy mills.
