Ceramic Foundry Sand is made by fusing, spraying, sieving, and purifying high alumina calcined bauxite. They can be used in casting all sizes of steel parts. The spherical shape produces high-density material with excellent flow characteristics, available in a variety of AFS sizes. The main chemical composition is Al2O3 which provides excellent refractoriness and stability. With the excellent casting property feedback and lower price. Ceramic foundry sand has already conquered the markets and is considered a direct replacement for chrome and zircon casting grade sands.
Ceramic Foundry Sand Characteristics and Casting Benefits:
- High AI2O3 mineral composition
- Higher refractoriness than silica-based sands (around 1850 C°)
- Much lower thermal expansion compared to chromite and zircon-based sands.
- Reduce burn-in
- Compatible with existing resin systems
- Regular spherical shape
- Provide a highly smooth surface
- Reduce binder addition
- Excellent air permeability and dispensability (reduce cleaning cost)
100% recyclable - Cost reduce (up to around 40 times against 5-10 times for chromite based sands)
