Molybdenum rod machining operations

Molding, sintering, drape forging, car light or polishing, machining.
Two. Classification of Molybdenum crucible rod
Material Category:
1, pure molybdenum rod: molybdenum content of greater than 99.95%.
     2, high temperature molybdenum rod (lanthanum molybdenum alloy bar): 0.4 to 1.2% lanthanum, molybdenum content of impurities outside the margin.
     3, TZM molybdenum rod: 0.4 ~ 0.6Ti, 0.07 ~ 0.12Zr, 0.01 ~ 0.05C.
Surface state by Category:
A sintered molybdenum rod: Surface silver gray metallic luster, density 9.8g / cc.
    2, forging molybdenum rod: the surface with a layer of oxide, black surface, the density 10.2g / cc.
    3, car light Molybdenum plate rod: the forging molybdenum rod by lathe machining, surface smooth, metallic luster.
   4, polished molybdenum rod: silver gray metallic luster, smooth surface, size small error.
III. Molybdenum rod surface oxide removal method
1, easily oxidized molybdenum products have properties. Severe oxide to be removed, with a strong acid (hydrofluoric acid, nitric acid, hydrochloric acid, etc.) processing, the operation note.
     2, mild oxide abrasive cleaning agent using the Add, with a soft cloth or sponge to wipe, then wash with warm water.
