- Wear parts – Excellent abrasion and erosion resistance for parts like valves, nozzles, and extrusion dies.
- Welding electrodes – Low thermal expansion and high melt point suit them for arc welding.
- High temperature furnace components – Withstand temperatures exceeding 2000°C.
Sports & Recreation
- Golf club counterweights – Improve swing efficiency through precise weighting of club heads.
- Diving weights – Suitably high density for divers to control buoyancy underwater.
- Fishing weights – Heavy yet compact weights to carry fishing lines deep underwater.
Benefits of Using Tungsten Alloy Powder
Compared to other materials, tungsten alloy powders offer some unique benefits:
- Tailored properties – Alloying additions allow properties like density, strength, and conductivity to be dialed in.
- Precise manufacturing – Powder metallurgy enables precise control over microstructure and composition.
- Design flexibility – Powders can be used in injection molding, 3D printing, and pressing/sintering.
- High performance – Capable of outperforming metals like steel and titanium in specialized applications.
- Cost-effectiveness – Using powders is often more affordable than machining dense tungsten alloys.
Thanks to these advantages, tungsten alloy powders enable high performance parts to be manufactured in a cost-effective manner across diverse industries.
