High-entropy alloys (High-entropy alloys) referred to as HEA, are alloys formed by five or more equal or approximately equal amounts of metals.    High Entropy Alloys that have been maturely melted include W, Ta, Mo, Nb, V, Cr, Zr, Ti, Hf, and other metals with equal atomic ratios and non-equal atomic ratios in high-entropy alloys. Ordinary components of Co, Cr, Fe, Ni, Cu, Al can be melted and cut by high entropy alloy of various systems according to the customer requirements of components, and processes. Because high-entropy alloys may have many desirable properties, they are highly valued in materials science and engineering.
