Tungsten Copper Powder Metallurgy

Tungsten Copper Electrode Picture

Tungsten copper powder metallurgy method is the choice of preparing fine tungsten, copper powder, soaked by the sintering process is refined class, can withstand high temperatures and nearly 2,000 high stress, with high melting point, high hardness, resistance to burning and good anti-adhesion resistance, electrical corrosion product surface finish, high precision, low loss. Preparation of alloy powder metallurgy method has good electrical and thermal conductivity, good high temperature strength and certain plasticity.

Powder metallurgy involves producing metallic powders and preparing a mixture from them with a given chemical composition and specific processing properties; molding powders or mixtures made with them into semi finished products of a given shape and size, chiefly by pressing; and sintering, or heating the semi finished products at a temperature below the melting point of the metal as a whole or of its principal component.

As the melting point of tungsten and copper vary greatly, tungsten melting point of 3410 ℃, much higher than the boiling point of copper and tungsten copper immiscible, so the tungsten-copper composite material prepared by powder metallurgy products out performance is much higher than the legal system prepared copper infiltration products. Further, the powder metallurgy method can improve the material's density.
