White Fused Alumina,Brown Fused Alumina,Calcined Brown Fused Alumina

Blasting Raw Materials

We are engaged in supplying and exporting of Garnet abrasives and Brown and White Fused Alumina.

Garnet Abrasives

Garnet abrasive is produced by processing beach sand and grading to exact speciffications. Due to its low free silica, Garnet abrasive is widely used in Grit blasting and now widely popular for waterjet cutting.
