My factory looking for distributors
Alumina ceramic ring slice are a type of ceramic parts. Alumina ceramic ring slicehave all the excellent characteristics of alumina products.
The monthly output of Alumina ceramic ring slice is 2,000-3,000, and the shipment time is 5-30 days.
Features of wear-resistant alumina eramic ring slice:
1. Alumina ceramic ring slice Large hardness
Alumina ceramic ring slice Measured by professional research institutes, its Loss hardness is HRA80-90, second only to diamond, and Alumina ceramic ring slice wear resistance far exceeds wear-resistant steel and stainless steel.
2. Alumina ceramic ring slice good wear resistance
Alumina ceramic ring slice after research and determination, its wear resistance is equivalent to 266 times that of manganese steel and 171.5 times that of high-chromium cast iron. According to our ten-year customer follow-up survey, the service life of the equipment can be extended at least ten times under the same working conditions.
3. Lightweight
Its density is 3.5g/cm3, which is only half of steel, which can greatly reduce the equipment load.
4. Wide range of application
Alumina ceramics is a very wear-resistant precision ceramic material, which is widely used in electronics, steel, smelting, machinery, coal, mining, chemical, medical, military, aviation, photovoltaic semiconductor and other fields. Companies with a lot of mechanical equipment wear can choose different types of products according to different needs.
