Seamless TZM Alloy Tubes Molybdenum Alloy Tubes Hollow Bars for Vacuum Furnace
TZM Molybdenum Alloy costs approximately 25% more than pure molybdenum and costs only about 5-10% more to machine. For high strength applications such as rocket nozzles, furnace structural components, and forging dies, it can be well worth the cost differential.
TZM alloy is available in tubes form in basically the same size range as pure molybdenum.
