Introduction and Applications

Advantage of Oxygen Free High Conductivity Tellurium Copper (OFT) :
oxygen content within less than 10ppm;  easy turning, high efficiency;  anti arc and anti adhesion;  conductivity≥93%

Remarks:
With the addition of deoxidizer, the oxygen content is  controlled at a very low level and stable; The turning is broken and the processing efficiency is equivalent to HPb59-1; Tellurium copper has arc resistance and fusion welding performance, excellent performance in high temperature environment;

 

The superior electrical conductivity of OFT makes it an ideal material for applications such as vacuum and direct current (DC) contacts, low-impedance and coaxial cables, and power connectors. This copper has a high temperature and current carrying capacity, allowing it to withstand extreme temperatures. Its superior machinability further allows for complex geometrical design for challenging production requirements.

OFT Tellurium Copper is a great cost-effective alternative to many other copper alloys and can be used for a wide range of applications. Its superior electrical and mechanical properties make it a great choice for electrical contacts, connectors, and components, and it has excellent corrosion, corrosion resistance, and machinability characteristics. It is available at a reasonable price, making it an ideal choice for large quantity orders for low-cost projects.
