5-10 Mesh Polishing Foundry Sand

Description

~Description:
 ~The fused foundry sand, also know as Nice Foundry Sand(NFS), is a kind of artificial foundry sand with granular appearance,   high heat resistance, low heat dilating rate, which is mainly made of Al2O3 and through high temperature calcined, fused, prilling and selecting. NFS has lower cost and better performance than Chromite sand and zircon sand. It  provides an effective way to improve the quality of the foundry with cost-down and less damage to the environment.

~The ***0 mesh polishing foundry sand is a large particle sand with diameter **4 mm, dark brown color, smooth surface, moderate hardness, high toughness, good self-sharpening, and low consumption. It can be recycled used for polishing and cleaning of copper and aluminum.
