5x TOUGHER THAN BROWN OR PINK ALUMINIUM OXIDE DISCS.
Zirconium Oxide (also called Zirconia)
Zirconia grain is well suited to high pressure machining and grinding applications. Zirconia grain also has a good heat resistance. Zirconia abrasives work best in the grit range 24 to 120 grit.
Zirconia abrasives are commonly used in general steel fabrication shops where they have become the abrasive belt and disc of choice for the grinding and finishing of steel, they are also commonly used in stainless steel applications however some of the new ceramic abrasive products supplied by KO WELDING are revolutionising metal grinding applications.
Although zirconia is tougher than aluminium oxide it will struggle to effectively grind mill scale.
