Fabrication Process
The density of pure molybdenum is brought close to the theoretical density by means of isostatic pressing, high temperature sintering and thermal deformation processing, so as to obtain the best possible high temperature performance.
Advantage
Pure molybdenum has a high melting point, elastic modulus, good electrical and thermal conductivity, good high temperature strength and low thermal expansion coefficient.
