WA1 ceramic grade has a unique combination of superior wear resistance, toughness and flaking resistance as a result of adding SiC Whiskers to Alumina. WA1 is primarily used in machining continuous cuts of aerospace alloys because of its productivity and reliability characteristics. WA1 can also be used to machine gray cast iron and hardened steels because of its excellent thermal shock resistance.
