The company specializes in zirconia ceramics and alumina ceramic parts production finishing manufacturers, can be customized according to customer drawings or samples, accuracy up to ±0.0001mm, surface finish can be polished up to mirror Ra0.1.
We mainly produce finishing ceramic rod, ceramic tube, ceramic cup, ceramic plate, ceramic sucker, ceramic blade and other special-shaped ceramic structural parts, ceramic materials are mainly alumina, zirconia, silicon carbide, silicon nitride, aluminum nitride ceramics.
High temperature resistance, wear resistance, corrosion resistance, acid and alkali resistance, antimagnetic, pressure resistance.
Alumina Ceramic Features:
1. High temperature resistance, up to 1600℃
2. High hardness, Vickers hardness of 1500HV0.5, its hardness is second only to diamond.
3. Light weight, density of 3.65g /cm3, only half of steel, can greatly reduce the load of equipment.
4. Environmental protection and insulation
Zirconia Ceramics Features:
1. Higher hardness, its density is 6.05g/cm3, higher hardness than alumina ceramics.
2. Excellent wear resistance, its wear resistance is equivalent to 266 times of manganese steel, can prolong the service life of equipment more than 10 times.
3. High toughness, high toughness, unbreakable, high bending strength and high compressive strength.
