95 insulated alumina ceramic wear-resistant lining

95% insulating alumina ceramic wear-resistant lining is a high-performance ceramic material mainly composed of high-purity alumina (Al ₂ O3), with an alumina content of up to 95%. This material is made through high-temperature sintering process and has extremely high hardness, strength, wear resistance, and excellent electrical insulation performance. Its Rockwell hardness can reach HRA90 or above, second only to diamond, and its wear resistance far exceeds manganese steel and high chromium cast iron. At the same time, the material also has excellent corrosion resistance, thermal shock resistance, and electrical insulation, which can maintain stable performance under harsh working conditions.

95% insulating alumina ceramic wear-resistant lining is usually fixed on a metal substrate in the form of ceramic sheets or ceramic tubes through bonding, welding, embedding, etc., forming a composite structure. This structure combines the high wear resistance of ceramics with the high strength and processability of metals, and is widely used in various equipment linings that require high wear resistance and insulation properties.
