High Purity Silicon Nitride Riser Tube For Low Pressure Casting

High Purity Silicon Nitride Riser Tube For Low Pressure Casting

Silicon nitride riser tube has many excellent characteristics, such as corrosion resistance, low thermal-expansion confficient and long service life. It is ideal material of the metallurgy industry because of the excellent oxidation resistance, heat-shock stability and no reaction with the metal solution.

Feature:

1. Excellent strength & good compactness

2. Low thermal expansion coefficient

3. Excellent thermal shaock resistance

4. No wetting by molten aluminium and other ono-ferrous molten metal

5. Good corrosion resistance

    

Application:

Widely applied in aluminium alloys casting, non-ferrous metal metallurgy etc
