ceramic Fluid handling components such as pump plungers, liners, tubes, shafts, pistons and cylinders
Ceramic Mechanical seals, ceramic valve seats, and ceramic control valve components
ceramic Thread guides, ceramic screws, ceramic spray nozzles
ceramic Industrial knives and blades
High purity alumina ceramics:
99.99% Alumina ceramic; 99.9% Alumina ceramic
Ordinary alumina ceramics:
99.7% Alumina ceramic,99.5% Alumina ceramic,99% Alumina ceramic,97% Alumina ceramic,96% Alumina ceramic,95% Alumina ceramic.
Alumina reliability:
Better wear resistance
Higher volume resistivity
Greater mechanical strength
More chemically inert
