Customization 99.95% Molybdenum Products Tungsten Molybdenum Glass Stirring Bar
Tailored By Customer Tungsten Molybdenum Glass Stirring Bar As Molybdenum Products
The stirring bar can eliminate glass bubbles when stirring glass solutions, to obtain molten glass with uniform temperature, thus ensuring the quality and finished product rate of finished products. Glass stirring bars are widely applied to the industries of optical glass, electronic glass, vessel glass and toy decoration glass.
With extremely strong high-temperature strength as well as difficult erosion from most of molten glass, tungsten-molybdenum materials are the optimal materials for manufacturing glass stirring bars.
Advantage:
- High melting point of 2600℃
- Excellent creep behaviour
- Good dimensional stability
- Excellent corrision resistance
- Good electrical and thermal conducting
