Tungsten-tantalum-zirconium-hafnium alloy powder is an alloy system based on four refractory metal elements: tungsten (W), tantalum (Ta), zirconium (Zr), and hafnium (Hf). Through the synergistic strengthening and microstructure regulation among the elements, it has formed an advanced material with ultra-high melting point, excellent high-temperature mechanical properties, and outstanding corrosio
