We have a 6061-T651 aluminum piece that is hard coat and they PTFE sprayed. Our customer is highly concerned in their application how hard this material is. From my research everything points to Rockwell C 60-70 but what would that be in Mohs? what is the conversion factor? I had one place tell me its Mohs 4 and someone else tell be that because its an Aluminum Oxide finish it will be 9.5 on the Mohs chart.
