alumina ceramic insulator ceramic heating element tube

Alumina ceramic insulator ceramic heating element tube Product Pictures   Product Details     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.        Product Features   -Heat resistance -Wear resistance -High strengh
-Good insulation
-Used in all electric products, electric heating products and wear resistant machinery parts. -OEM, ODM and OBM are welcomed   Alumina ceramic is kind of structural ceramics, with insulation resistance, voltage resistance, high strength,  good thermal conductivity, dielectric loss, stable electrical performance characteristics. Used in electronic ceramic substrates,  ceramic electrical insulation, vacuum devices, devices porcelain, spark plugs and other products.  We can make the part by hot injection pressing, dry pressing,  isostatic pressing and extrusion productive technology etc.
