Ceramic Elemental Part Alumina Disc Automotive Pump Components Anti-corrosion Wear Resistance
Alumina or aluminum Oxide, Al2O3 is a major engineering material, and is the most widely used fine ceramics material. This material has superb material characteristics such as high electrical insulation, high mechanical strength, high wear and chemical resistance. Because of the universal existence of aluminum and oxygen, the price of alumina material maintain a comparatively lower price than other materials.
A well-formed crystal structure is formed for this metallic oxide during sintering. For this reason, the parts made from it have good performance of corrosion resistance, are insoluble in weak acid or alkaline solution, let alone normal water or medical fluid. The ceramic alumina parts are only slightly soluble in strong acid and alkaline solution.
It works with other alumina ceramic components in a gear-type oil pump of cars to transfer lubricating oil precisely and durably, without corrosion by the oil. It economically reduces the gas consumption for the lighter density comparable to metal parts.
