Detailed Product Description

 

High Hardness Wear Resistance Alumina Ceramic Ceramic Insulator Sheet

 

 

Aluminum ceramic Sheet 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.

Product features : 

 

Applicable to make ceramic wrist watch, watch ctrap, bracelet, ring and necklace etc. With the property of abrasion resistance, invariant color, elegance and shining, ceramics are the ideal decorative material for watch and jewelry industry. All the ceramics can be customized.

 

1. High hardness.

2. High heat resistance : Alumina ceramic has excellent thermal stability,which means that it is

     widely used in areas where resistance to high temperatures is essential.

3. Good wear resistance : Alumina ceramic is the material of choice for alumina wear parts.

4. High electrical resistivity : Alumina is an electrically insulating material.

5. High corrosion resistance : It is insoluble in water and only slightly soluble in strong acid and

alkaline solutions. Good chemical stability of alumina leads to high corrosion resistance.

 

Quality assurance:

1. High heat resistance : Zirconia ceramic has excellent thermal stability,which means that it is widely used in areas where resistance to high temperatures is essential.
2. Good wear resistance : Zirconia ceramic is the material of choice for wear parts.
3. High corrosion resistance : It is insoluble in water and only slightly soluble in strong acid and alkaline solutions. Good chemical stability of alumina leads to high corrosion resistance.

Alumina ceramic is 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.
