Aluminum oxide produces a matte finish with very few micro-scratches as opposed to silicon carbide of the same size that produces a very micro-scratched finish. Silicon carbide is significantly more expensive than aluminum oxide, so even though it cuts much faster it may still be more economical to tolerate the longer process time of aluminum oxide processing.
