Appearance: Divided forging molybdenum rod and polished molybdenum rod; forging molybdenum rod surface is allowed to have oxidize film and slight forging hammer mark; polished molybdenum rod surface presents metallic luster and has no oxidized phenomenon notably; The two surfaces have no defects, such as divided layer, crackle, burr and vertical crackle, etc.
Purity: Mo 99.95%
Specification: Dia(0.8-16) x L (mm). The diameter and length deviation are consulted by both parties according to GB4188-84 standard or user s demand
Applications: Used for making electric vacuum device and electric light source parts
Molybdenum rod is manufactured as random length pieces or cut to customers' desired lengths. In addition, there are three different surface processes or finishes which are provided, depending on the desired end use of the molybdenum rod.
FOTMA produces pure and lanthanated doped molybdenum rod. The lanthanated doped molybdenum rods are targeted for use in higher temperature applications where ductility is retained after recrystallization for material with smaller cross sections
Molybdenum rod 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.
