Tungsten Alloy Rod For EDM Electrode Material Copper Tungsten Metal Alloys
1. Tungsten Alloy Rod For EDM Electrode Material Copper Tungsten Metal Alloys:
Early EDM electrodes employed copper or graphite electrodes, which are inexpensive but not resistant to ablation; tungsten-copper alloy electrodes have largely taken their place. High temperature resistance, high high temperature strength, arc ablation resistance, superior electrical and thermal conductivity, and quick heat dissipation are all benefits of using tungsten copper electrodes. Applications mainly concern high voltage discharge tube electrodes, resistance welding electrodes, and EDM electrodes.
2. Shape of Tungsten Alloy Rod For EDM Electrode Material:
Electric machining electrodes are characterized by a wide variety of specifications, small batches and large total quantities. The tungsten-copper alloy material used as an electrical machining electrode should have the highest possible density and uniformity of structure, especially for slender rod-shaped, tubular and special-shaped electrodes.
So we accept custom,process as per customer's request.
3. Density and Relative Density of Low Loss Rate Tungsten Copper Alloy EDM electrode:
| Grade of Tungsten Copper Alloy | W-Cu10 | W-Cu20 | W-Cu30 | W-Cu40 | |
| p | g/cm3 | 17.30 | 15.67 | 14.31 | 13.17 |
| r1 | % | 97.85 | 97.38 | 96.96 | 96.42 |
| r2 | % | 99.36 | 99.46 | 99.38 | 99.63 |
| △r | % | 1.51 | 2.08 | 2.42 | 3.21 |
| r3 | % | 96.82 | 96.68 | 96.43 | 96.81 |
4. Conductivity of Low Loss Rate Tungsten Copper Alloy EDM electrode:
The following table shows the conductivity of tungsten copper electrode materials. Among them, a1 is the conductivity of tungsten-copper alloy before HIP, a2 is the conductivity of tungsten-copper alloy after HIP, △a is the net increase in conductivity caused by HIP, and a3 is the conductivity of the corresponding tungsten-copper contact material required by the national standard. The HIP treatment greatly improves the density of the tungsten-copper alloy, and accordingly the electrical conductivity is also significantly improved.
