TZM is a particle-strengthened molybdenum based alloy containing titanium, zirconium and carbon.

Advantages of TZM compared to pure molybdenum:

Above 1100°C tensile strength is about twice that of unalloyed molybdenum

Better creep resistance

Higher recrystallization temperature

Better welding properties.

General Properties:

Density: 10.16 g/cc at 20°C

Recrystallization Temperature: 1425 to 1595°C

Stress-Relief Temperature: 1 hour at 1095 to 1260°C

Liquidus Temperature: 2620°C

Chemical Composition:

TZM: Mo + 0.40~0.55%Ti + 0.06~0.12%Zr + 0.01~0.04% C
