Quken can provide the Tungsten-Copper alloy and Tungsten-sliver alloy.
Tungsten copper alloys are the perfect choice where high density, high thermal conductivity, or low thermal expansion are important. Electrical contacts, heat sinks, and resistance welding electrodes are all applications where tungsten copper alloys can do the job.
Quken offers Tungsten-copper products as below:
| Composition | Standard | Density (gr/cc) | IACS (%) | Hardness (HB Kgf/mm2) | Bend Strength (MPa) | Typical Application | |

Tungsten-silver alloy contains between 15-70% silver and are mainly used for electrical contacts—generally heavy-duty devices subject to high current. Silver tungsten combines the high thermal and electrical conductivity of silver with the arc resistance of tungsten.
Quken offers Tungsten-Sliver alloy as below:
| Composition | Standard | Density (gr/cc) | Resistivity (20°C, μΩ.cm, ≤) | Conductivity (IACS%, ≥) | Hardness (HB Kgf/mm2 ≥) | Bend Strength (MPa ≥) | Available Size (mm) | Typical Application | |
