Sintered Metal Bars

Pure tungsten is a hard metal from steel gray to tin white. Very pure tungsten can be cut open by a pull saw (pure tungsten is brittle and difficult to work). Tungsten is processed by forging, drawing and impact. Among all metals, tungsten has the highest melting point (3422°C), the lowest vapor pressure and the highest tensile strength (1650°C). Its anticorrosive properties are very good, and most inorganic acids have little erosion on it. In air it forms a protective layer of oxide on its surface, but at high temperatures it is completely oxidized. A small amount of tungsten can greatly increase the hardness of steel.

Sintered molybdenum bar by electron beam melting and zone melting system degrees in the density of more than 99.99% (4n) process of molybdenum or molybdenum sheet is tasted. With electron beam melting method first refining molybdenum bar, molybdenum bar in the smelting process of gas and solid impurities due to evaporation, evaporation under high temperature and high molybdenum to obtain higher purity, structure compact set of ingot, and then further purified by the zone melting method, electron beam melting molybdenum ingots, said impurities under high temperature and high molybdenum evaporation and driving role to improve the purity of molybdenum again region, obtain high pure molybdenum or single Item.
