TA0015 Tantalum-Tungsten Wire (Ta-W-Draht)

Tantalum-Tungsten Wire Description

Tantalum-tungsten is a high-strength metal alloy. It exhibits a high melting point, tensile strength and corrosion resistance. SAM’s tantalum alloys are produced using powder metallurgy, whereby tantalum powder is mixed with alloying elements and placed in moulds. The components are then compacted at pressures up to 2 000 bar and subsequently sintered. Tantalum-tungsten alloys are stronger than pure tantalum and are suitable for corrosion and high-temperature applications up to 1 600 °C, making them a reliable material for wire production.
