1.Description
Our industrial ceramic parts include, tube, rod, plate, disc, wafer, ring, seal, bearing, valves, pump plunger, beam, roller, shaft, screw, washer, sleeve, hunger, spacer, holder, carrier, insulator, fixture, clamp, chuck, nozzle, guide, frame, lining, and grinding media, milling ball or beads.
These precision toleranced ceramic components or assemblies are used in a wide range of semiconductor, electronic, electrical, mechanical, chemical, automotive, textile and the other industrial engineering applications, due to their extreme hardness, more resistances to wear, heat, corrosion, high electric insulation, and low thermal expansion.
