3. Craft of 75%W Tungsten Copper Disc For PCD Application:
The technological process of preparing tungsten----copper alloy by powder metallurgy method is powder milling ---- ingredient mixing ---- pressing and forming ----- sintering and infiltration ----- cold working.
4.Performance of 75%W Tungsten Copper Disc For PCD Application:
Our tungsten copper alloy discs have high physical and mechanical properties, which can well meet the needs of PCD tool disc erosion. We put a lot of effort into researching and optimizing our processes, in order to meet the further needs of our customers and to develop high-quality products. Our copper-tungsten alloys are classified into grades 10, 11 and 12. Copper tungsten electrodes for EDM, PCD tool disc erosion have the following advantages:
- High conductivity and regular components keep the electrical pulse generator stable;
- High thermal conductivity ensures that PCD tools are not damaged by heat;
- High density ensures minimum roughness on PCD insert surface.
Tungsten copper alloy disc the advantages of copper and tungsten, high strength, high specific gravity, high temperature resistance, arc ablation resistance, good electrical conductivity, good processing performance. Isostatic pressing (high temperature sintering-copper infiltration) is used to assure product purity and accuracy ratio, fine structure, and outstanding performance. High-quality tungsten powder and oxygen-free copper powder are employed. Good arc breaking performance, good electrical conductivity, good thermal conductivity and small thermal expansion.
