More info

Tantalum-Tungsten (TaW) excels due to its sensible mechanical properties and glorious corrosion resistance. We add between 2.5 and 10 percent by weight of tungsten to pure tantalum. Though the ensuing alloy is up to 1.4 times stronger than pure metal, it remains simple to work at temperatures of up to 1600 °C. Our Tantalum tungsten alloy (Ta2.5W, Ta10W) is thus specially well suited for the heat exchangers and heating components used in the chemical instrumentation construction field.
