High Pure Aluminum Oxide / Al2O3 / Alumina Ceramic Plunger, 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 times.
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.
Main Technical parameters:
Bulk Density≥3.6 g/cm3
ROHS Hardness HRA≥85
Compressive Strength≥850 Mpa
Fracture Toughness KΙC ≥4.8MPa•m1/2
Coefficient of thermal conductivity: 16W/m.K
Coefficient of thermal expansion:7.2×10-6m/m.K
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.
