polished molybdenum rods/bars:
Molybdenum bar is used as vacuum material, cathode for emitting tube, high temperature electrodes etc.
1) Specification:
Mo content: Mo>=99.95%
Density: >=10.2g/cm3
Dia: 2.5-120mm
surface:polished,ground,cleaned
2) Surface Finish
Black – Surface is “as swaged or “as drawn”; retaining a coating of processing lubricants and oxides.
Cleaned - Surface is chemically cleaned to remove all lubricants and oxides.
Ground - Surface is centerless ground to remove all coating and to achieve precise diameter control
