Red color fused alumina Aluminum oxide abrasive powder

Red color fused alumina Aluminum oxide abrasive powder

Since there’s demand for high roughness in the abrasive tool industry. Iridium coated aluminum oxide is developed. It is calcined with a compound-Iridium coating on the surface of each grit under a high temperature. After this treatment, the special iridium coated aluminum oxide gets an excellent advantage in roughness, better ability to bond, better water affinity, higher self-sharpening ability.

Thus, when making boned abrasive and coated abrasive tools, the grit is more easily bonded with bonder such as resin, glue, ceramic.

Abrasive tools such as cutting wheel, grinding wheel, flap disc adopting with iridium coated aluminum oxide will perform sharper with longer life, higher work efficiency.

Red color fused alumina Aluminum oxide abrasive powder Features:

Improvement Comparing with normal WFA abrasive material

There are two kinds of Iridium coated aluminum oxide:

1.       Red color: the coating is with Fe2O3.

2.       White color: coating with non Fe2O3 Iridium. Suitable for contaminant-free abrasive tools working for aviation, food, medical field. And suitable for green color cutting discs.
