Molybdenum's prime alloy is TZM. This alloy contains 99% Mo, 0.5% Ti and 0.08% Zr. TZM offers twice the strength of pure molybdenum at temperatures over 1300°C.
The recrystallization temperature of TZM is approximately 250°C higher than molybdenum and it offers better weldability than pure molybdenum.
TZM's finer grain structure and the formation of TiC and ZrC in the grain boundaries inhibit grain growth and the related failure of the base metal as a result of fracturing along grain boundaries.
This characteristic also gives it better properties for welding. TZM generally costs around 25% more than pure molybdenum but in high heat and strength applications it can be well worth the cost differential.

TZM is generally available in sheet and foil in the same size ranges as pure moly with the exception of very thin foil.
