Product Description

Plate iridium white alumina (iridium coated aluminum oxide)

 

Description:

Since there’s demand for high roughness in abrasive tool industry. Iridium coated aluminum oxide is developed. It is calcined with a compound-Iridium coating on surface of each grit under a high temperature. After this treatment, the special iridium coated aluminum oxide gets a 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.

 

 

Improvement Comparing with normal WFA abrasive material

Micro hardness	Roughness	Water affinity	Self-sharpness
Increase 10%	Increase 10%	Increase 350%	Increase 15%

 

 

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.

Application:

1. Bonded abrasive cutting and grinding wheel.
2. High quality refractory.
3. Spray material
4. Technical ceramic products.
5. Molding sand for precision casting.
