We provide 99.95% Moly Rod / Molybdenum Round Bar diameter 1 - 100mm For Sapphire Industry Molybdenum ruond bar is resistant to corrosion when the humidity is below 60%. Molybdenum round bar is made of by high quality molybdenum raw material with high melting point, corrosion resistance, high density, good thermal conductivity and electrical conductivity. However, it must be protected at elevated temperatures. Molybdenum can oxidize in the presence of oxidizing gases at temperatures above 250�° C. Despite this vulnerability, Molten glass, nitrogen, inert gases, molten metals and ceramic oxides only slightly affect it. Moly bars have high melting point so it's suitable for very high-temperature applications. It is also characterized by a uniquely low coefficient of thermal expansion and a very high level of dimensional stability. Molybdenum Round Bar: Purity: Mo 99.95% Appearance: Silver gray metal luster This product is made with Mo-1 The impurity content accords with GB3462-82 standard Molybdenum products have the properties of high melting point, good thermal conductivity and low thermal expansion. At high temperature, they can resist oxidation and have high strength without any distortion during the procession, etc.
