Luoyang Hong Feng Refractories and Abrasives Co., Ltd

It is one kind of black silicon carbide abrasives grain, To get the kind of grains, we specially process the ingots, separate the magnetic material, and sieve the grains carefully to get a complete range of grit sizes.

As an abrasive, CF-16 is used in making vitrified bonded grinding wheels, resign bonded grinding wheels. As loose grains, it is widely used for pressure blasting, surface finish and other general industrial applications.
