 Description
Ceramic Foundry sand is made from fine 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.
 
Advantages
Spherical grain, low thermal expansion, good anti-breakness, well refractory, low density, neutral materials
 
Application
Waterglass bonded sand, resin bonded sand, precision casting, Expendable Pattern Casting (EPC), Copper and Aluminium articles polishing
 
Packing
*5kg/bag or others
