TZM Molybdenum

TZM is an acronym for titanium-zirconium-molybdenum, and is typically manufactured by powder metallurgy or arc-casting processes. It is an alloy that has a higher recrystallization temperature, higher creep strength, and higher tensile strength than pure, unalloyed molybdenum. Available in rod and plate form, it is often used for hardware in vacuum furnaces, large x-ray equipment, and in creating tools. While incredibly versatile, TZM is best utilized between 700 and 1400°C in a non-oxidizing environment. Our TZM is of the highest quality and conforms to ASTM B386 type 364 and B387 type 364 standards.
