Abstract

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.
