ZA25 Zirconia Fused Alumina is a unique abrasive grit for it’s durable grinding ability. It is not suitable for wear resistance component and sandblasting, but also especially for grinding wheels such as heavey duty grinding wheel,centerless grinding wheel and heavy load cutting disc.
ZA25 Zirconia fused alumina is produced from zirconium material and Alumina with a electrofusing process. The zirconium and aluminum oxide element mixed thoroughly to get a kind of crystal with small crystal size and tight structure. That special structure make the ZA25 Abrasive grain extremely durable.
ZA25 Zirconia Fused Alumina Characteristic:
- Excellent toughness and self-sharpening ability.
- Small crystal size at 10-20um. That make Zirconia abrasive grit get longer service life.
- High strength even in case of heavy load.
