Coated Abrasives
Fiber Disc

Fiber Disc is made with heavy duty vulcanize fiber as backing, strict selection of abrasive grain and bond with specially formulated resin. Vulcanize fiber backing provides high tension strength to hold abrasive grain together. Fiber disc is flexible to allow maximum contact to the area of work piece.

Abrasive Grain Application:

Brown fused alumina (A)

It is made by fusing bauxite in an electric arc furnace under high temperature.

Feature: Good amount of toughness, hardness and self-sharpening. Great entry price. 

Zirconia Alumina (ZA)

It is made by fusing alumina and zirconia with electric arc furnace under high temperature.

Feature: Highly wear resistant, very durable, self-sharpening, outperform brown fused alumina.

Application: General metal, stainless steel. 



Black Silicon Carbide (C)

Black silicon carbide uses silica sand andpetroleum coke as raw material. The mixture is synthesized with Acheson process.

Hardness: Lower than diamond, higher than brown fused alumina.

Feature: Sharp, high hardness, brittle.

Application: Non-ferrous metal, non-metal material, masonry, cement, wood.
