Special Copper Alloy WireCOPPER ALLOY WIRE

An integrated manufacturing from the melting/forging process to finish plating process.
A wide variety of alloy is available to fulfil various types of customer needs with superb strength, electrical and thermal conductivity, machinability, malleability, corrosion resistance and cold workability etc.

Special Copper Alloy Wire

Copper-Iron Alloy Wire It is a Cu-Fe-P base alloy also known as US standard CDA194. Because of its superior strength and conductivity, it is widely applied for package pins for plastic and contact materials for hybrid cars.
Silicone Bronze Wire It is widely known as MIG-wire (Everdur). It is a Cu-Si-Mn base alloy and new MIG arc brazing material. The significant characteristic of this material is that it can joint thin plates (1mm or less).
Copper Wire with Lead It is a Cu-Pb-P base alloy and offers superb free-cutting performance and conductivity (IACS 70% and higher). Because of its significant characteristics, it is widely applied for artificial satellites, air crafts and bullet train (Shinkansen) connectors.
Tellurium copper Wire It offers a high level of machinability and electrical/thermal conductivity, and its mechanical properties does not easily deteriorate under a high temperature condition. It is widely applied to connectors, electrode wire for electrical discharge machining and torch nozzles.
Corson Based Copper Wire This alloy is best suited to replace beryllium copper and offers a high strength and superb electrical/thermal conductivity. It is widely used for components for relay switches, connectors and terminals.
