Hardness evaluates a fabric's capacity to resist mechanical don and abrasion. Alumina ceramics surpass metal and tungsten carbide resources in hardness. Over the Rockwell hardness scale, alumina ceramics range from HRA80-90, inserting them slightly below diamonds and higher than stainless steel. Uniaxial pressing requires compacting alumina powder by applying pressure https://advanced-ceramics54729.life3dblog.com/33344770/the-basic-principles-of-aluminum-nitride-ceramics
