Product Specifications
Olivine Sand, as a foundry and refractory aggregate, olivine is noted for its high fusion point, low uniform thermal expansion, and its remarkable ability to resist fracture from thermal shock. Olivine has been famous for years in producing excellent non-ferrous castings, monolithic and basic Refractories and a key raw material for Manganese Steel Castings. Today, more foundry men are realizing that olivine works equally well in Cast Iron and Stainless Steel.
