Alumina ceramic is a type of ceramic material mainly composed of aluminum oxide (AI2O3), used as an insulating material for electrical components. Alumina ceramic has good conductivity, mechanical strength, and high-temperature resistance. Its characteristics make it one of the most widely used ceramics in structural, wear, and corrosive environments.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n

Alumina ceramics<\/p>\n

1. High hardness<\/p>\n

Rockwell hardness is HRA80-90, the hardness is lower than diamond, far more than the wear resistance of wear-resistant steel and stainless steel.<\/p>\n

2. Excellent wear resistance<\/p>\n

Measured by professional research institutions, its wear resistance is equivalent to 266 times of manganese steel. Gaoming cast iron 171.5 times, according to our more than ten years of customer tracking survey, under the same working conditions, can extend the service life of the equipment at least ten times more.<\/p>\n

3. Light weight<\/p>\n

Its density of 3.5g\/cm3 is only half that of steel, which can greatly reduce equipment load.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n
