What Are The Commonly Used Refractory Metals?

The commonly used high-melting-point metals in the industry are collectively referred to as refractory metals such as tungsten, molybdenum, niobium, tantalum, and zirconium. The refractory metals have a high melting point, a high density, a stable crystal structure, a large activation energy, and difficult cutting operations. Mainly refractory metal, add other alloying elements to form refractory metal materials.

With the development of science and technology, refractory metals have been more and more widely used in the fields of atomic energy, aerospace, machinery, electronics, chemicals, medical care, textiles, and light industry. The refractory metal commonly used in tungsten has the highest melting point (3380°C) and the highest density (19.1g/cm3), while molybdenum has the largest elastic modulus of 343 350MPa.
