Product characteristics of tellurium copper
Tellurium copper is an alloy material made by adding trace tellurium element on the basis of pure copper. The addition of tellurium significantly improves the cutting performance of the material, while maintaining the excellent electrical and thermal conductivity of copper. Copper telluride has a conductivity of over 90%IACS and a thermal conductivity of over 350W/m·K, which makes it an ideal material for the manufacture of precision electronic components.
In terms of mechanical properties, tellurium copper exhibits excellent strength and hardness.
Its tensile strength can reach more than 300MPa and hardness can reach 80HB, which is far better than ordinary pure copper materials. At the same time, tellurium copper also has good wear resistance and fatigue resistance, which can meet the requirements of long-term use.
Tellurium copper is also superior in processing properties. Its cutting performance index can reach more than 80%, which is much higher than that of ordinary copper alloys. This feature greatly improves the production efficiency and reduces the processing cost. In addition, tellurium copper also has good welding properties and surface treatment properties, which is convenient for subsequent processing.
