Tungsten Copper Combination Electrode

Tungsten copper alloy has a combination of tungsten and copper, high temperature resistance, arc ablation, high hardness, high melting point, high strength, high specific gravity, high conductivity, high thermal conductivity, easy cutting, anti-adhesion, and has a transpiration cooling characteristics. Using isocratic pressing - high-temperature sintered tungsten skeleton - copper infiltration process, the production of copper content 6-90% of various large, shaped pieces, high purity, uniform organization performance; compression molding, extrusion molding, injection molding can produce all kinds of sheets, rods, tubes, plates, and shape of the various models of complex products.

Tungsten copper combines with iron to the composite electrode, to eliminate the pores, cracks problem exists in the past, this process uses a welded composite. Tungsten, copper and iron composite electrode composite made of for both tungsten copper, iron materials, combined with high strength, good electrical conductivity.

1. A reasonable mix of tungsten copper, iron, and its mechanical properties is more reasonable, more convenient to use. The small precision electrode machining deformation problem is a good solution;

2.The electrode is directly adsorbed on the the magnetic work bench grinding after processing, flatness, surface finish and dimensional precision are other processing methods are not comparable. Exudes a sense of superiority in the processing of large planar electrode;

3. The electrode after grinding benchmark reproduction is good, especially suitable for the electrode need a multi-step combinations work;

4. A plurality of electrodes can be processed at the same time, can greatly improve the work efficiency;

Tungsten Copper Powder Metallurgy

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.

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.
