Product Description
Physical Properties:
In addition to its mechanical properties, tellurium copper alloy also boasts several desirable physical properties. It has good thermal conductivity, which ensures efficient heat dissipation in applications where heat management is crucial. This property makes it suitable for various electrical and thermal conductivity applications. Furthermore, tellurium copper alloy has excellent corrosion resistance, making it resistant to tarnish and oxidation. This attribute extends the lifespan of components made from this alloy, particularly in harsh environments or exposed to corrosive substances.
Machinability:
Tellurium copper alloy is renowned for its exceptional machinability. The presence of trace amounts of tellurium imparts self-lubricating properties to the alloy, reducing friction and minimizing tool wear during machining. This significantly improves the efficiency of the machining process and helps in achieving close tolerances and high-quality finishes. Moreover, the alloy's high machining speeds and feeds make it an attractive choice for industries where productivity and cost-efficiency are important factors.
