Wearable Abrade-resist Aluminum Oxide Ceramic Brick, Bending
Strength ≥ 290MPa
Wearable ceramic is the special corundum ceramic that been sintered
under 1700℃ with the main raw material of Al2O3 and flux of rare
metal oxide. Using the high strength organic/inorganic bond to felt
together, and then grinding to the size as drawing required.
1. Big hardness, the ROHS hardness is HRA80-90, just inferior to
diamond, the wearable ability is much better than the wearable
steel and stainless steel
2. Wearable ability is excellent. Equal to 266 times of manganese
steel, 171.5 times of high chrome cast-iron. Under the same working
condition, can extend the equipment working life at least above 10
3. Light weight, the bulk density is 3.6g/cm3, only half of steel,
can alleviate the equipment burthen greatly.
4. Hard adhesives, good heat-resistant.
The enterprises of
field ,will choose the different products according to their
special requirements for the wearable mechanical instruments that
works in the system of coal transfer, material transfer, milling,
dust removing, and so on.
