1、 Core advantages

1. Extreme temperature resistance

The melting point is as high as 2610 ℃, and the conventional operating temperature is 1100 ℃~1800 ℃. Some models can be stably used in ultra-high temperature environments above 2000 ℃.

2. Ultra high purity

Molybdenum powder purity ≥ 99.95%, density ≥ 9.8g/cm ³, ensuring zero pollution of melted materials.

3. Stability

Corrosion resistance: resistant to acidic/alkaline environments and molten rare earth metal corrosion;

Thermal shock resistance: 550MPa tensile strength, no deformation or cracking at high temperatures;

Low thermal expansion: The coefficient of thermal expansion is 4.8 × 10 ⁻⁶/℃, ensuring thermal cycling stability.

4. Precision machining performance

Support machining, spinning, sintering and other processes, with a wall thickness accuracy of ± 0.05mm, and surface smoothness directly affects the quality of crystal growth.
