Some kinds of refractory metals and its alloy were melted using vacuum levitation melting technology

such as V and V-Ta alloys

Nb and Nb-Ti alloys

Mo and Mo-Ti alloys

Ta and Ta-Ti alloys

Co-Cr-W

et al.The technology has its own advantages in the shape of raw materials not required strictly and uniform component and microstructure because of being melted fully and electromagnetic stirred fully as well as in the accuracy of alloy elements content because of the adding method being controlled

eliminating effectively the impurity elements in the vacuum melting condition.Finally

the products which have specified shape and size can be obtained through casting after melting.
