Electric Thermal Aluminum Oxide Ceramic Sheet For Insulation , High Density
High temperature thin insulator alumina ceramic substrate for pcb use
1. Description
Alumina ceramic part is made from the most mature of the engineering ceramics, offering excellent electrical insulation properties together with high hardness and good wear resistance, but relatively low strength and fracture toughness. Alumina ceramics are generally white but may also be pink or ivory. The color is derived from either the sintering additives or impurities in the raw materials.
2.Alumina ceramic advantages:
-Heat resistance
-Wear resistance
-High strengh
-Good insulation
-Corrosion resistance
-Used in all electric products, electric heating products and wear resistant machinery parts.
-OEM, ODM and OBM are welcomed
