Alumina Ceramic Ring Slice
My factory looking for distributors
Advantages of Alumina Ceramic 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 its wear resistance is equivalent to 266 times that of manganese steel and 171.5 times that of high-chromium cast iron.
3. Lightweight
Its density is 3.5g/cm3, which is only half of steel, which can greatly reduce the equipment load.
Applications of Alumina Ceramic Ring Slice
1. Alumina eramic ring slice is a very wear-resistant precision ceramic material.
2. Alumina eramic ring slice which is widely used in electronics, steel, smelting, machinery, coal, mining.
3. Alumina eramic ring slice which is widely used in chemical, medical, military, aviation, photovoltaic semiconductor and other fields.
4. Companies with a lot of mechanical equipment wear can choose different types of products according to different needs.
