Product information

Model number: QTe0.5 
QTe0.5 Tellurium bronze is a wear-resistant copper alloy with copper as the base material and 0.4% - 0.7% tellurium added. It possesses high electrical conductivity, thermal conductivity and machining performance. 

Chemical composition
The main components are copper (≥99.2%) and tellurium (0.4% - 0.7%), and the content of impurity elements (such as lead, bismuth, etc.) is strictly controlled. 

Physical properties
‌Electrical conductivity‌: The conductivity can reach over 90% of pure copper (≥58 MS/m), and the thermal conductivity is approximately 350 W/(m·K), close to that of pure copper. ‌
‌Density‌: 8.9 g/cm³, close to the density of pure copper. ‌ Mechanical properties
‌Tensile strength‌: After cold processing, it can reach 350 - 1000 MPa (the values vary greatly depending on the processing state). ‌
‌Elongation‌: 15% - 25%, combining strength and plasticity. ‌
‌Hardness‌: HV 120 (≈ HRB 85), suitable for wear-resistant components. ‌
Cutting performance
The cutting resistance is reduced by 30% - 50% compared to pure copper, with high surface finish, which can meet the processing requirements of precision turning, milling, etc. ‌
Corrosion resistance
It has good stability in dry atmosphere and non-oxidizing media, but requires surface protection in environments containing sulfur and chloride ions. ‌
Typical applications
‌Electronics and electrical engineering‌: Semiconductor package pins, relay contacts, high-voltage switch contacts. ‌
‌Vacuum equipment‌: Vacuum tube electrodes, ion sputtering targets. ‌
‌Automobile and communication‌: 5G base station connectors, new energy vehicle charging port interfaces. ‌

Product parameter

Chemical composition 
The chemical composition of QTe0.5 tellurium bronze is as follows:
‌Copper (Cu): ≥ 99.2% (matrix metal)
‌Tellurium (Te): 0.40% - 0.70%
‌Phosphorus (P): 0.004% - 0.012%
‌Other impurities: ≤ 0.01% (such as lead, bismuth, etc.) ‌
The addition of tellurium significantly improves the cutting performance of the alloy, while the phosphorus element is used to refine the grains and improve processing characteristics.
