The material of LED Lamp Base is mainly used for 95% or 99% alumina material . This is an eviromental material . For Car big lamp, we also usually used for Steatite material . We can design the lamp base according to our customer drawing .   Alumina Ceramic Part Introduction: Ceramic parts provides excellent high temperature resistance, size stability, electric insulation, thermal shock resistance, extremely corrosion and wear resistance.   Alumina Ceramic Part Application: Furnace process tubes Steel tube liners Coal handling wear resistance pads Thermocouple protection tubes Sandblasting nozzles Wire drawing dies Bushings and caps Crucibles Tool bits Saggers Kiln furniture Mechanical seals Fuel cell parts Rollers for hearth furnaces Welding nozzles Laser parts Gas igniters Electric insulator Ceramic guiders Ceramic screwdrivers Zirconia oxygen Sensors Medical and surgical components Alumina Ceramic Part Technical Date:

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
