棕刚玉
型号: AE-17H It is one kind of 棕刚玉 grains with blocky grain shape and high bulk density. To get this kind of product, we calcine the regular grains at a high temperature to give a blue colour, the purpose is to renovate the crack on the surface and interior of crystal and then to improve the As an abrasive, the AE-17H is mainly used in making vitrified and organic bonded grinding wheels for working in heat sensitive metals and alloys. Process way: High temperature treated;Barmac process |
