Product Description
Fused Zirconia Alumina is a premium abrasive material composed of aluminum oxide and zirconium oxide. It combines the hardness of aluminum oxide with the toughness of zirconia, resulting in superior grinding performance and extended service life.
Available in two main grades—ZA25 (25% ZrO₂) and ZA40 (40% ZrO₂)—this abrasive is ideal for heavy-duty grinding, cutting, and surface preparation applications on hard materials.
Main Applications
- Grinding wheels for steel and stainless steel
- Coated abrasives (sandpaper, sanding belts, discs)
- Blasting media for surface preparation
- Precision grinding and cutting operations
- Heavy-duty metalworking applications
- Surface finishing and deburring
ZA25
Lower zirconia content for versatile grinding applications
ZA40
Higher zirconia content for heavy-duty operations
