Te Copper

Tellurium bronze material, American ASTM standard grade C14500, is a high-conductivity, easy-to-machine copper alloy developed by the United States in the 1960s based on its industrial development needs. This material filled the gap in copper alloy precision machining materials and has been widely used in various industrial fields due to its excellent performance.

Chemical composition of tellurium copper strip:
GNEE	National Standard/American Standard	Cu	Te	P	O
	QTe0.3	Balance	0.2-0.3	≤0.012	≤0.003

Tellurium copper strip QTe0.3 (JT118) is a high-conductivity, arc-resistant alloy that can meet low temperature rise and high voltage arc resistance tests at the application end. It is suitable for high voltage DC relays, connectors, automotive terminal connectors, etc.

Easy Machinability

 

Tellurium copper C14500 contains 0.4-0.7% tellurium. The addition of this trace element significantly improves the cutting performance of copper, making it an ideal precision machining material.

 

High Conductivity and Thermal Conductivity

 

Tellurium copper C14500 retains the high electrical conductivity and high thermal conductivity of copper, making it suitable for electrical components requiring high conductivity and applications requiring efficient heat dissipation.

 

Corrosion Resistance and Arc Erosion Resistance

 

Tellurium copper C14500 exhibits excellent corrosion resistance and arc erosion resistance in various environments, extending the material's service life.

 

Excellent Cold and Hot Processing Properties

 

Tellurium copper C14500 has good cold and hot processing properties and can be processed by forging, casting, extrusion, drawing, and stamping.
