Features
1. High fire resistance, strong thermal shock resistance, help to improve the product after casting yield;
2. High purity, less impurities, casting surface quality is good;
3. The product is neutral, reduce the probability of chemical sand sticking;
4. Reasonable particle grading, good sphericity, angular coefficient close to 1.0, contribute to good shell strength, good air permeability;
5. Low density, the same casting, less use;
6. Suitable for all kinds of stainless steel, carbon steel, alloy steel, heat-resistant steel, etc.
