Molybdenum Products – Powder Metallurgy (P/M)
The production of molybdenum involves compaction of less than 99.95% pure powder into billets, followed by sintering and making into finished wrought forms. The process uses only the highest commercially pure powders.
Either the PM or
vacuum arc-casting process is used to fabricate TZM alloy (0.50 Ti, 0.08 Zr, balance Mo). The presence of titanium and zirconium carbides improves the strength and creep resistance at higher temperatures. TZM molybdenum alloy maintains toughness at higher service temperatures when compared to pure molybdenum. The abrasion resistance property of arc cast material makes it suitable for use in injection molding nozzles.
Simuwu offers the only commercially available arc cast molybdenum and tungsten alloy with 70wt% Mo and 30wt% W, demonstrating superior service life while handling high purity molten zinc (99.99% Zn). Using the P/M method, Simuwu manufactures Mo 75wt% and W 25wt% alloy to serve as heat shields in furnaces.
The P/M process is used to consolidate MHC (1.2% Hf, 0.1% C) alloys composed of hafnium carbide. MHC alloys exhibit high thermal conductivity, low thermal expansion, and high recrystallization temperature.
