| Sinters W/Cu base (infiltrated material) | |||
| Code | Composition % | Typical applications | Description |
| K0/0 | 70 W - 30 Cu | - Hard metal electroerosion (EDM) |
The presence of tungsten in the alloy provides it with an excellent resistance to wear and in all those conditions in which the thermal stresses are too much severe for the traditional copper alloys. |
| K0/1 | 75 W - 25 Cu | ||
| K0/2 | 77 W - 23 Cu | ||
| K0/3 | 80 W - 20 Cu | ||
| Sinters W/Wc/Cu base, hard quality (infiltrated material) | |||
| Code | Composition % | Typical applications | Description |
| HW/25 | 54W - 20Wc - 26 Cu | - Stainless steel welding |
The presence of tungsten carbide improves its hardness and its resistance to wear together with a good workability. |

| Code | Composition % | Typical applications | Description |
| WG2 | 70 W - 30 Ag | - Electric welding |
They are used above all for their antioxidant capacity. The alloy's silver quantity improves its conductibility but reduces its resistance to electric arc wear. |
| WG3 | 80 W - 20 Ag | ||
| WG4 | 75 W - 25 Ag | ||
