Foundry sand AFS30, AFS35, AFS40, AFS50, AFS60 Ceramic Sand For Sale
Product Description
Fused ceramic sand, also called ceramic Foundry Sand, is a kind of man-made spherical shape ceramic particle featured by high refractoriness, a low thermal expansion made by spraying melted from the fused bauxite. At the present, Ceramic sand is acknowledged worldwide as the newest and the best ideal sand for the foundries and has a very wide feasibility of applications for future development.
