It is a composite of tungsten and copper.
The composition of tungsten and copper are well-proportioned and accurate percentage; 2.
The tungsten and copper products have good size control, surface finish and flatness.
Tungsten and copper requires the application of high-density, low gas content, compared to the higher weight.
W30Cu tungsten and copper products discharge wire cutting speed is relatively slow, is a normal phenomenon.
By choosing the right mixture of tungsten and copper, we are able to influence the product's arc erosion properties.
Meanwhile, different content for tungsten and copper may result in the different properties for thermal expansivity and heat conductivity.
This refractory metal composite material is a combination of tungsten and copper.
Tungsten and copper solution is neither to each other nor is form intermetallic compounds are uniformly mixed by a two-phase single organization"pseudo-alloy".
The tungsten and copper corrosion, high speed, low loss rate, the exact shape of the electrode, excellent processing performance, to ensure the accuracy of the workpiece are greatly improved.
Resistant tungsten and copper corrosion, high speed, low loss rate, precise electrode shape, excellent processing performance, to ensure the accuracy greatly improve the parts to be machined.
Therefore, the use of the power processing more based on tungsten and copper materials.
The physical properties of both tungsten and copper make them not mutually soluble, meaning that one cannot be combined with the other, similar to the way oil and water will not mix.
Activated liquid phase sintering: In the W-Cu system by adding asmall amount of Co, Ni, Fe, Pd and other activated elements as the alloy in the middle phase can increase the miscibility between tungsten and copper.
High-temperature liquid phase sintering: As a large difference between tungsten and copper, it can directly use above the melting point of copper high temperature liquid-phase sintering to promote its densification.
Compared with tungsten, copper molybdenum copper, with a small mass, easily processed,linear expansion coefficient, thermal conductivity and mechanical properties of some of the main advantages of tungsten and copper quite.
This is because the wetting angle between the tungsten and copper is small, limiting the mobility of liquid copper, the pores can not completely eliminate, thereby to raise the sintering temperature only to increase the density.
MA(Mechanical Alloying): After high-energy ball milling and other processing and to achieve the mechanical alloying between tungsten and copper tungsten copper powder corresponding sintering method.
This is because the electrical conductivity of AlN is lower than that of tungsten and copper in the matrix, and the increase in the content of AlN inevitably leads to an increase in resistivity, or decrease in the electrical conductivity.
It integrates such features of tungsten and copper as high temperature resistance, electrical arc ablation resistance, high proportion, good electrical and heat conductivity, being easy to cut and transpiration cooling.
Pure tungsten and copper, tungsten copper electrode uniform material, low content of gas and impurity, very high burn-off resistance, excellent thermal and electrical conductivity, all necessary joining and machining processes.
