Tellurium copper is a kind of tellurium bronze material, American ASTM standard grade C14500, is a high-conductivity free-cutting copper alloy material successfully developed by the United States in the 1960s according to its industrial development requirements, to fill the gap of copper alloy precision machining materials . The tellurium copper alloy material has both good cutting performance and excellent electrical and thermal conductivity, and at the same time has corrosion resistance and electrical ablation resistance, good cold and hot processing performance, and can be forged, cast, extruded, drawn, and punched Molded. The products can be processed into profiles such as plates, sheets, rods, wires, tubes, and a variety of special profiles.
Introduction to Copper Tellurium
Copper tellurium refers to an alloy of tellurium and copper. Copper tellurium containing 0.4-0.7% tellurium has good cutting performance; copper telluride containing 50% tellurium and 50% copper is used as an intermediate alloy.
Material performance
Copper tellurium (C14500) alloy has good cutting performance, excellent electrical and thermal conductivity, and corrosion resistance; it is the copper alloy material with the best cutting performance among high-copper alloys; and has good cold and hot processing performance, and can be forged , Casting, extrusion drawing, punching and molding, upsetting.
Application field
The alloy is mainly used for: precision electronic and electrical components that require high conductivity, high conductivity, and corrosion resistance, advanced electromechanical parts, forgings and thread cutting parts, plumbing fittings, electrical contacts, plasma and laser cutting parts, automobile starters and switches Parts etc. The products can be processed into profiles such as plates, sheets, rods, wires, tubes, and a variety of special profiles. With the country’s vigorous advancement of new energy vehicles in recent years, the vigorous construction of charging piles, the requirements of charging pile contact materials for arc resistance, service life and safety performance have all new indicators. Since 2010, copper tellurium has been due to its excellent electrical The performance and easy processing characteristics have been successfully applied to the field of high-current connectors for new energy vehicles.
