Black Silicon Carbide Lapidary Rock Tuling Grits
Silicon Carbide has a lower hardness and abrasive capacity than diamond and/or boron carbide (both are which 9+ on the Mohs hardness scale). Yet because of its much lower cost when compared with diamond or B4C, it is widely used for grinding nonferrous materials, finishing tough and hard materials, as well as filling up ceramic parts.

Scratch Test | Some Meteorite Information | Washington …
Bottom Line: If you have a rock that bites into glass and makes a scratch mark like the two at the top of the photo above, then it contains quartz and it is not a meteorite. If your rock does not make a scratch, then the rock is still probably not a meteorite because many terrestrial rocks do not contain quartz.
Super Hard (70 Rc) High Speed Steels - Maxamet, Rex …
2019/12/2· Those more recent carbide replacement steels coine high vanadium (5% or greater) along with high hardness (>69 Rc) for very high strength and wear resistance. However, the first of these carbide replacement steels, in my opinion, was ASP60 by Stora, the earliest reference to which I can find is from 1975 .
