Subject: Silicon Carbide Black (2005-11-07 00:49:25)
Standard: CF-16
Number:

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.
