Molybdenum Alloy (Titanium-Zirconium-Molybdenum)tzm
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.
Molybdenum Alloy Advantages compared to pure Mo:
TZM material has better creep resistance and higher recrystallization temperature .
TZM has better high-temperature strength and better welding properties.
Molybdenum Alloy Typical areas of application:
TZM can be used to make components for HIP, sintering and heat treatment furnaces, and boats for annealing and sintering processes (temperatures up to 1400 'C)
TZM can be used for rotating anodes for medical diagnostics and forming tools such as hot runner nozzles for plastic injection moulding .
TZM can be used to make moulds for light-alloy casting and billets for the isothermal forging.
MoW (Molybdenum-Tungsten)
The alloying of molybdenum with tungsten leads to better corrosion resistance against molten zinc. We produce standardized MoW alloys with 30 weight% of tungsten (MOLY B60) and 50 weight% W.
MoW Advantages compared to pure Mo:
higher recrystallization temperature (approx. 100 'C)
better corrosion resistance against molten zinc .
higher strength.
MoW Advantages compared to pure W:
better formability
lower density
MoW Typical areas of application:
components for zinc processing, e.g. pump components, nozzles, thermocouple sheaths .
stirrers for the glass industry .
Sputter targets for coating technology.
