Copper Alloy No. C18700 is a copper-base alloy containing lead (nominally 1.0%). The lead is added to impact free-cutting properties to the metal. Although the lead lowers the electrical conductivity of Alloy No. C18700 slightly below that of tough-pitch copper, it still has high electrical conductivity well within the limits needed for most current-carrying requirements. Typical uses comprise electrical motor and switch parts, electrical connectors and screw-machine parts requiring high conductivity. 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-441. Producer or source: Copper and copper alloy mills.

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.
