Tantalum tungsten (TaW) alloy is also an alloy material composed of two transition metal elements, which has excellent physical and chemical properties and is widely used in aerospace, aviation, navigation, military, national defense, medical and other fields. Currently, commonly used brands include Ta10W and Ta2.5W. Tantalum tungsten alloy is a high-density material with high melting point, high tensile strength, good dynamic ductility, and corrosion resistance.
