Molybdenum Alloy Rods (Titanium-Zirconium-Molybdenum Rods)
TZM is a solid-solution hardened and particle-strengthened
molybdenum based alloy. The development of a Mo-Ti solid solution
and the fine dispersed Ti-carbides are responsible for the
excellent strength properties at temperatures up to 1400'C. The
average nominal chemical composition in weight%: 0.5 Ti, 0.08 Zr,
0.02 C, remainder Mo.
The finer grain structure of TZM alloy and the formation of TiC and
ZrC in the grain boundaries of the moly inhibit grain growth and
the related failure of the base metal as a result of fractures
along the grain boundaries. This also gives it better properties
for welding.
Dimensions and Tolerances of TZM Alloy Rods:
Diameter(mm) | Diameter Tolerance | Length(mm) | Length Tolerance |
16-20 | +1.0 | 300-1500 | +2 |
20-30 | +1.5 | 250-1500 | +2 |
30-45 | +1.5 | 200-1500 | +3 |
45-60 | +2.0 | 250-1300 | +3 |
60-100 | +3.0 | 250-800 | +3 |
Other sizes and tolerances can be made as per customers' request.
