Hafnium Zirconium Molybdenum Properties
Why should we use Hafnium zirconium molybdenum(ZHM alloy) ?
Hafnium Zirconium Molybdenum(ZHM alloy) is a molybdenum alloy which room-temperature tensile strength is higher than TZM molybdenum alloy of approximately 40% to 50% and it t is the highest intensity molybdenum alloy.
Hafnium zirconium molybdenum properties are as follows:
| Material | Elements Symbols | Density(g/cm3)20℃ | Melting Point(℃) | Boiling Point(℃) |
| Molybdenum | Mo | 10.28 | 2610 | 5560 |
| Hafnium | Hf | 13.310 | 2222±10 | 4603 |
| Zirconium | Zr | 6.511 | 1852±2 | 3530 |
| Carbon | C | 2.267~3.515 | 3727 | 4827 |
High temperature tensile strength and elongation of ZHM alloy:
| Material | Elements Symbols | Temperature(℃) | Mons’ Hardness Scale | Tensile strength(MPa) |
| Molybdenum | Mo | 1000 | 5.5 | 2500~3300 |
| Hafnium | Hf | 1000 | 5.5 | 1500 |
| Zirconium | Zr | 1000 | 5 | 3000 |
| Carbon | C | 1000 | 1~10 | 4000 |
Thermal Properties of ZHM Alloy Composition:
| Material | Elements Symbols | Thermal Expansion(/K) | Thermal Conductivity(Wm·K) |
| Molybdenum | Mo | (5.5~6.2)×10-6 | 1.38 |
| Hafnium | Hf | 6.73×10-6 | 23 |
| Zirconium | Zr | 9.6×10-6 | 22.7 |
| Carbon | C | 8×10-6 | 119~165 |
ZHM alloy is still in the development stage, mainly processed into ingots was built, as super alloy powder isothermal forging die and it must be widely applied in the future.
