Welding properties of various copper alloys
Welding properties of various copper alloys: 1. The thermal conductivity of red copper is high. The thermal conductivity of red copper at room temperature is about 8 times larger than that of carbon steel. It is difficult to locally heat the copper weldment to the melting temperature. Therefore, ...Read more -
Performance Advantages of Cast Copper Alloys
1. Process characteristics: Most copper alloys have large shrinkage, that the solidification sequence should be controlled during casting to stop the formation of shrinkage cavities. Tin bronze is well oxidized within the liquid state, that the flow shouldn’t be interrupted during pouring. ...Read more -
