Copper Tungsten Alloy High Temperature Sintering

The tungsten-copper alloy is an alloy composed of tungsten and copper.
The copper content of common alloys is 10% to 50%.
The alloy is prepared by copper tungsten alloy powder metallurgy method and has good electrical and thermal conductivity, good high temperature strength and certain plasticity.
At very high temperatures, such as above 3000℃, the copper in the alloy is liquefied and evaporated, which absorbs a large amount of heat and lowers the surface temperature of the material.
So this type of material is also known as metal sweating material.

Since the Copper Tungsten Alloy two metals are incompatible with each other, the tungsten-copper alloy has low expansion property of tungsten, abrasion resistance, corrosion resistance, high electrical and thermal conductivity with copper, and is suitable for various mechanical processes.
The process of preparing tungsten-copper alloy by powder metallurgy method is: milling – batching mixing – pressing forming – sintering infiltration – cold working.

Copper tungsten alloy high temperature sintering, The tungsten-copper or molybdenum-copper mixed powder is subjected to press molding and then sintered in a liquid phase at 1300 to 1500℃.
The material prepared by this method has poor uniformity and many closed voids, and the resulting density is usually lower than 98%.
However, the sintering activity can be improved by adding a small amount of nickel to the activated sintering method, mechanical alloying method or oxide reduction method to prepare ultra-fine and nano powder, so as to improve the density of tungsten-copper and molybdenum-copper alloys.
However, nickel activation sintering can significantly reduce the conductivity and thermal conductivity of the material, and mechanical alloying can also reduce the conductivity of the material by introducing impurities.
It is difficult to prepare powder by oxide co-reduction method because of complicated process and low production efficiency.
