Description

Tantalum-Tungsten (TaW) excels due to its good mechanical properties and excellent corrosion resistance. Between 2.5 and 10 percent by weight of tungsten are added to pure tantalum. Although the resulting alloy is up to 1.4 times stronger than pure tantalum, it remains easy to work at temperatures of up to 1600 °C.
