Hard Choices: Diamond or CBN? | Gear Solutions …
These include non-ferrous metal grinding (copper or aluminum alloys); cermets of ceramic (cemented tungsten-carbide, metal matrix composite Al-Si-C); and glass, silicon, granite, or marble. While the crystal structure of diamond and CBN is very similar, there is one difference: the carbon atoms of the diamond crystal structure have four valence electrons.
While aluminum oxide has lower hardness and abrasive capacity than diamond, boron carbide, and silicon carbide, it is widely used for grinding ferrous materials, finishing tough and hard materials, filling up ceramic parts when the processing cost is important.

Abrasive Grains: Choose the right sandpaper for your …
While silicon carbide tends to wear quicker than aluminum oxide, it is also sharper and more friable, therefore it is still a long-lasting product and is ideal for uses on harder materials, rougher surfaces, and for polishing, due to its hardness and sharpness.
Grip Tape vs Non Slip Tape, is There a Difference?
Mineral hardness is measured by the MOHS scale, both aluminium oxide and silicon carbide register the same mineral hardness, 9. 1 is talc and 10 being diamond. Silicon carbide retains its place in grip tape usage mainly as an ''old school'' remnant, reminding boarders of its vintage 1970s roots, in performance there is little difference with aluminium oxide offering better quality output.
