Ceramic sand for shell mould sand casting
Ceramic Foundry sand is made from high quality bauxite, by re-fused and blown to ball type. With advantage of fine surface smooth finish and air permeability, it is a new type casting material for precision casting, coated sand and self hardening sand etc. Chemical and Physical Composition: Main Chemical Composition: Al2O3≥75% Fe2O3≤5% TiO2 ≤5% SiO2:5%-20% Physical
