96 alumina ceramic substrate is a kind of ceramics widely used in structural ceramics. Because it has excellent electrical properties at high frequencies, its dielectric loss is small, volume resistivity is large, strength is high, hardness is large, linear expansion coefficient is small, and wear resistance and heat resistance are also very good.
The 96 alumina ceramic substrate is a special ceramic sheet made of Al2O3 as the main raw material, rare metal oxide as a flux, and roasted at a temperature of more than one thousand degrees. The 96 alumina ceramic refers to the oxidation with a content of 96% Aluminum ceramic substrate.
96 alumina ceramic substrate performance characteristics:
1. High hardness
As measured by the Shanghai Institute of Ceramics, the Chinese Academy of Sciences, its Rockwell hardness is HRA80-90, second only to diamond in hardness, far exceeding the wear resistance of wear-resistant steel and stainless steel.
2. Excellent wear resistance
As measured by the Powder Metallurgy Research Institute of Zhongnan Polytechnic University, its wear resistance is 266 times that of manganese steel and 171.5 times that of high-chromium cast iron. According to our customer tracking survey for more than ten years, under the same working conditions, the service life of the equipment can be extended by at least ten times.
3. Light weight
Its density is 3.5g/cm3, which is only half of that of steel, which can greatly reduce the equipment load.
4. Wide application
For example, coal, conveying systems, milling systems, ash discharge, dust removal systems, etc. of thermal power, iron and steel, smelting, machinery, coal, mining, chemical, cement, port and terminal companies can all be based on Choose different types of products for different needs.
