Tungsten-based metal matrix composites (W-MMC) specifically combine the special properties of tungsten with the properties of other metals. Tungsten has the highest melting point of all metals and therefore also the highest application temperatures. Its very low coefficient of thermal expansion and high dimensional stability are also unique. We specifically influence and supplement these properties by combining tungsten with other metals. This results in tungsten-based metal matrix composites with special properties, including tungsten heavy metals (WHA) and tungsten-copper composites: DENSIMET®, INERMET®, DENAL®, WCu, and SPARKAL®.
