Tungsten Alloy Suppliers Tungsten Metal Wolfmet

As mention, tungsten has a melting point in excess of 3,000°C, it also cannot be cast, extruded or easily formed. Using our knowledge in powder metallurgy techniques we produce tungsten in the form of metal matrix composites. These tungsten alloys can then be machined by conventional techniques to produce very complex and exacting parts.
