Product Description
Factory Price Al2O3 Insulating Alumina Ceramic Screw Cap
Product Description:
Alumina ceramic is Al2O3 as main raw material, in the rare metal oxide as flux, special ceramic sheets after one thousand degrees high temperature roasting into.
Alumina ceramic Al2O3 content is high, the structure is relatively compact, with special properties, it is known as the special ceramics. The Al2O3 ceramic materials are densely arranged six party structure for oxygen ion and aluminum ion, filled in 2/3 with eight sides in the gap, which is the same with natural corundum stable alpha Al2O3 structure, so the ceramics with high melting point, high hardness, good wear - resistance.
Alumina Insulating pellets are an insulating material that is used in conjunction with a thermal pad to insulate the screw and the metal sheet of the heating component to avoid short circuit between the shell of the electrical chip and the heat sink.
Feature:
1.High hardness
2.Extremely abrasive resistance performance
3.Light weight
4.Wide scope of application
Performance:
Physical properties: high insulation resistance, breakdown, high temperature resistance, abrasion resistance, high strength (three meters altitude fall not broken)
Fire rating: USA military standard MIL-F-51058 (the highest level)
Typical application: strong current, voltage, strong high temperature parts, IC MOS, IGBT power tube heat pipe insulation
