Molybdenum TZM Alloy Bars Moly Alloy Spuare Bars Surface Machined / Black

TZM Alloy Square Bars (Titanium-Zirconium-Molybdenum Bars)
TZM offers twice the strength of pure moly at temperatures over 1300° C.
The recrystallization temperature of TZM is approximately 250° C higher than moly and it offers better weldability.
TZM Molybdenum is an alloy of 0.50% Titanium, 0.08% Zirconium and 0.02% Carbon with the balance Molybdenum. TZM Molybdenum is manufactured by either P/M or Arc Cast technologies and is of great utility due to its high strength/high temperature applications, especially above 2000\'F.

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.

Features of TZM Alloy Bars:

Composition: Ti: 0.4-0.55% Zr: 0.06-0.08%, Mo: 99.2% to 99.5% C: 0.01-0.04%
Density: 10.1g/cm3
Purity: Mo ≥ 99.20%
Density: ≥ 10.10g/cm3
Diamension: By users\' drawing
Appearance: It`s black brown, and will turn to a silver metallic luster after alkali-washing
Application: Used in high-temperature vacuum and hydrogen-atmosphere furnace construction.
