 It can be plastic with corundum. This part needs to have three physical properties: fire resistance, wear resistance and thermal shock stability. Because of the inconvenient construction of the parts, it is made of wear-resistant plastic. This material is composed of three reasons; (1) the alumina aggregate plays a role in fire resistance; (2) Al2O3 powder, which plays a role of thermal shock stabilization; (3) Corundum material, which plays a role in wear resistance.
