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 -
Use of special brass
In order to meet the requirements of making structural parts, it is widely used in the industry to add alloying elements to copper to make copper alloys with enhanced properties. Brass is a copper alloy with zinc as the main alloying element, which has good mechanical properties and is easy to pr...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 -
What are the ways to identify pure copper
1. Check the hardness: the higher the fineness of copper jewelry, the softer the texture and the whiter and smoother the surface. Copper alloy manufacturers take copper bracelets of about 60 grams as an example. If they are pulled open by hand, there is no elasticity, and their fineness is about ...Read more -
