Product description

Technical data

The performance and aggressiveness of brown fused alumina type WIWOX® NK produces a strong removal effect as well as a uniformly structured surface. The high TiO₂ content makes it extremely hard and tough, whereby the surface roughness can be greatly changed. Also available as microcorn with a precise grain distribution up to 3 μm.


Suitable blasting processes

  • Pressure blasting process
  • Injection blasting process

Applications

  • Grinding, lapping and polishing medium
  • Ceramic grinding wheels and grinding media
  • Wear-resistant and refractory products
