Single Crystal Aluminium Oxide

With ultra-clean, smellless, single crystal aluminium oxide can be used in manufacturing vitrified, resinoid-bonded, rubber-bonded wheels and abrasive belts, which are suitable for grinding and polishing stainless steel, high-speed steel and heat sensitive steel.

  • Characteristics:
    1. With multi-layer grain, SA can create lots of cutting sides continually. So the surface of grinded workpiece can reach 
    the same cleanliness and the service life of workpiece is improved.
    2. Number of single crystals of SA is around 95%.
    3. Good toughness: the compressive strength of SA exceeds 26N.
    4. Al2O3 of SA is above 99.4%.
    5. SSA can be combined with all kinds of bonding agent.
    6. Excellent self-sharpening, high grinding efficiency.
