Al2O3 powder for polishing Tungsten Molybdenum Alloy is an excellent polishing powder for stainless steel, aluminum alloy, copper, glass, and other materials. Electrofused aluminum oxide powder from us is an electrofused aluminum oxide powder. It is an aggressive grinding powder with high hardness, good toughness.

Pure molybdenum is handled in much the same way as tungsten. It really should be joined in a high purity atmosphere after an involved chemical cleaning process. If it is to be TIG welded, run-off tabs should be utilized to prevent crater cracking at the end of each pass during welding. DCEN polarity is used and heat input is kept to a minimum.

Investigations were carried out into the process of oxidizing roasting the sludge waste of R6M5 high-speed tool steel to extract, from the sludge, tungsten and molybdenum by sublimating and condensing the oxides.The developed phenomenological and mathematical models of the process were used to determine the technological parameters of combined sublimation of the …
