Advantages of Zirconia fused alumina Abrasives:
1. High Hardness: Zirconia fused alumina abrasives have extremely high hardness, which can reach above 9.5, much harder than ordinary abrasives such as quartz and steel. This makes it have excellent wear resistance and pressure resistance during grinding and polishing, and can complete the work more efficiently.
2. High Strength: Zirconia fused alumina abrasives have high strength and are not prone to breakage or crushing. This makes it safer and more reliable in high-speed cutting and polishing applications.
3. Excellent Grinding Performance: Zirconia fused alumina abrasives have good self-sharpening and self-grinding properties, which can maintain a sharp cutting edge, and can automatically remove surface debris during grinding, reducing the accumulation of cutting heat, thereby reducing friction and thermal stress during grinding, and improving cutting efficiency and precision.
4. High Temperature Resistance: Zirconia fused alumina abrasives have excellent high temperature resistance, can maintain good hardness and strength in high temperature environments, and are not easy to soften or melt. This makes it perform well in high temperature cutting and polishing applications.
5. Good stability: Zirconia fused alumina abrasive has high chemical stability and is not easily corroded by chemicals such as acids and alkalis. This allows it to be used in a variety of environments and is not easily affected or damaged by external factors.
Disadvantages of zirconia fused alumina abrasives:
1. Poor thermal conductivity: Poor thermal conductivity, easy to generate excessive heat during high-temperature cutting and polishing, may cause problems such as thermal cracks and surface deformation.
2. High preparation difficulty: Due to the high melting point and preparation difficulty of zirconia fused alumina abrasives, its production process is relatively complex and expensive. This also limits the wide application of zirconium corundum abrasives.
