Technical Support

1. Low thermal expansion rate, reduce casting deformation and improve surface quality;
2. High refractoriness, good thermal and chemical stability, low volatile matter, resistance to sticky sand and veining defects;
3. The particles are round and solid, with low angular coefficient and smooth surface; good fluidity, easy filling, good air permeability, which can reduce the pore defects of castings
4. Appropriate and uniform strength, low residual strength at high temperature; easy to clean up afterwards;
5. The compactness and bulk density are small, which reduces the trial amount, labor intensity and cost;
6. Thermal shock resistance, low impurity breaking rate, and high recycling rate.
