Annealed Molybdenum Alloy TZM Tube High Power Electron Tube
ASTM B387 TZM Molybdenum Alloy Sheet Heat Shield for High Temperature Furnace
Description
TZM alloy is the most outstanding molybdenum alloy high temperature material at present. It is a solid solution hardening and particle strengthened molybdenum alloy. TZM is harder than pure molybdenum metal, and has higher recrystallization temperature and better creep resistance degeneration. The recrystallization temperature is about 1400℃, far higher than that of Mo, can provide better solderability.
Chemical composition
| Element | Ti | Zr | C | Mo |
| Content, % | 0.4-0.5 | 0.08-0.12 | 0.01-0.04 | balance |
Adding rare earth elements can not only improve the molybdenum recrystallization temperature and high temperature creep resistance, but also significantly reduce the brittle transition temperature of molybdenum, increase the ductility, improve the brittleness of the room temperature brittleness and high temperature anti sagging ability.

TZM Molybdenum Alloy Applications
Due to its excellent high temperature strength, high recrystallization temperature and good thermal conductivity, TZM alloy is widely used in the field of aviation and spaceflight, such as nozzle material, gas distribution valve, gas pipeline materials, electronic tube grid material, X-ray rotating anode parts, die casting, extrusion die, heating body and heat shield in the high temperature furnace, etc.
Production Process
The density of TZM alloy is close to the theoretical density by the method of static pressure molding, high temperature sintering and free forging, so as to obtain the best high temperature performance.
