Hardness evaluates a material's capacity to resist mechanical put on and abrasion. Alumina ceramics surpass steel and tungsten carbide resources in hardness. About the Rockwell hardness scale, alumina ceramics vary from HRA80-90, putting them just below diamonds and over stainless-steel. Alumina Ceramics have great electrical, don resistant, and significant temperature https://helena098iwk3.blogozz.com/profile
