Alumina Ceramic Insulator Plates Machinable Ceramic Sheet For Transistor Heat Sink
Company Advantage
OEM factory, High quality, Precision processing, Pipelining assembly, 100% QC process, Plentiful stocks, Fast and Safe shipping.
Aluminum ceramic plate is suitable for the IC, MOS transistors, schottky, IGBT and so on need to surface heat source of heat.
Alumina ceramic plates can withstand high temperature and maintain high strength and hardness. Alumina plates also have superb performances in electrical insulation, high chemical resistance and low thermal expansion. We have various sizes of semi finished shapes in stock and are able to conduct custom manufacturing for all kinds of alumina components.
Applications:
• Alumina plates are hard enough to become armor for personnel or vehicles.
• The corrosion resistivity of alumina plates makes them a great material for chemical industry.
• Used as a material for industrial furnaces due to its ability to maintain its hardness at high temperatures.
• Used for making parts for CVD, ion implants, photolithography, and semiconductor parts.
• In traditional industries, alumina ceramics are ideal for products such as injector tubes, gas nozzles and insulators.
