Copper Base Alloy

Abstract CDA C18700 is a copper-base alloy containing lead (nominally 1.0%). The lead is added to impart free-cutting properties to the metal. Although the lead lowers the electrical conductivity of CDA 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-533. Producer or source: Copper and copper alloy mills.

Insight Into

Most connectors are made from copper or copper alloys, with beryllium copper and phosphor bronze being the most common base materials due to their high electrical conductivity, low stress relaxation, and competitive cost. The most significant drawback is copper’s low resistance to corrosion, which can lead to electrical failure of connectors. For this reason, a layer of gold is often plated on the surfaces of connectors to seal off the base metal from being directly exposed to the environment. As an economical practice, gold flashing has been used to protect electrical contacts from corrosion. However, there is increasing evidence indicating that gold flashing can be detrimental in applications calling for long-term reliability. This paper provides insight into reliability issues of gold flash.
