Tantalum-Tungsten Tube & Tantalum-Tungsten Tube Description
Tantalum-Tungsten Tube & Tantalum-Tungsten Tube are a high‑strength metal alloy. It exhibits a high melting point, tensile strength and corrosion resistance. The tantalum alloys from SAM are produced via powder metallurgy processes. Tantalum powder is mixed with alloying elements, inserted into moulds and pressed at pressures up to 2 000 bar, then sintered. Tantalum‑tungsten alloys are stronger than pure tantalum. They are used in corrosive and high‑temperature applications up to 1 600 °C. Consequently, they are a practical material for tube production.
