White Fused Aluminium Oxide Micro Grits is a finer grade White Fused Alumina Powder with main content

 

Aluminium Oxide(Al2O3) made sieved by water pressure. It's a single crystal, self-sharpening, abrasion resistant

 

abrasives for precision grinding, polishing, cutting etc. White Fused Alumina finer grades are further graded into

 

FEPA sizes F280-F2500 for precision abrasives, cutting, blasting or polishing. It's also used for precision abrasive

 

tools for special equipment.

 

 

Applications of White Fused Aluminium Oxide Micro Grits

  •  
  • Grinding and Polishing on Precision Component, Semi-conductor Parts

 

  • Cutting and Etching on Metal and Non-metal Parts

 

  • Sand Blasting of Tooth Mold, Silicon Crystal, Semi-conductor Screen

 

  • Frosted Effect on Glass or Acrylic Surface

 

  • Precision Ceramics, Precision Casting/Foundry Sand

 

  • Fillings into Cosmetic Products

 

  • Aluminium Oxide Coating
