Low Temperature Sintering Infiltration Prepares Tungsten Copper Rod

Low temperature sintering infiltration prepares tungsten copper rod is an important method for the preparation of tungsten copper rod. Principle of low temperature sintering infiltration prepares tungsten copper rod is that tungsten powder mixed with a small amount of copper powder and sintering additives (usually nickel powder), at lower temperatures, pre-sintered in hydrogen, and then sintered materials were bleeding copper. In this method of preparing tungsten copper rod it should be noted that the reduction in the sintering process and degassing, and vacuum infiltration of copper and high vacuum degassing process, in order to obtain a vacuum tungsten copper rod low gas content.

Advantages of low temperature sintering infiltration prepares tungsten copper rod are that a simple process for the manufacture of copper content greater than 20% of tungsten copper alloy rod. Disadvantages of low temperature sintering infiltration prepares tungsten copper rod lie in that higher raw material content requirement, tungsten skeleton strong as high-temperature sintering, ablation phenomenon is easy to produce.
