Molybdenum lanthanum alloy rod is alloy rod of molybdenum and lanthanum. La2O3 is contained in molybdenum lanthanum plate to prevent wrong movement of molybdenum grain and re-crystallization of slow rhythm under high temperature. The density of molybdenum lanthanum plate is over 10.1g/cm3.
The average nominal chemical composition in weight:
La: 0.5-0.7%
Mo: the balance
Compared with pure Mo, TZM has the following advantages:
1) better creep resistance
2) higher recrystallization temperature
3) better high-temperature strength
4) better welding properities
5) higher tensile strength
1) Specification of MoLa rod, MoLa bar
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
3)Some Size with forged surface and tolerance:
