Feature of alumina ceramics plates:

Alumina ceramics plates have good conductivity, corrosion resistance, mechanical strength and high temperature resistance

1. High purity: High purity alumina ceramics plate is a highly competitive and stable material with a purity of more than 99%, which is an ideal high purity material.

2. Wear resistance: high purity alumina ceramics plate have extremely high hardness and wear resistance, and can be used in extreme environments such as high speed, high temperature and high pressure.

3. Good insulation: high purity alumina ceramics plate have good insulation properties, suitable for high voltage, high frequency and other occasions.

4. Good chemical stability: high purity alumina ceramics plate have good corrosion resistance to most chemical substances.

5. Good thermal stability: The high temperature resistance of high purity alumina ceramics is very excellent, and can withstand the temperature of up to 1750℃.

6. Biological inertia: high purity alumina ceramics plate are non-toxic and harmless to biological tissues, and have good biological inertia.

Advantages of alumina ceramics plate:

1. the hardness is determined by the Shanghai Institute of Silicate of the Chinese Academy of Sciences, the Rockwell hardness is HRA80-90, the hardness is second only to diamond, far more than the wear resistance of wear-resistant steel and stainless steel,

2.the wear resistance is excellent measured by the Powder Metallurgy Institute of Central South University, its wear resistance is equivalent to 266 times of manganese steel, 171.5 times of high chromium cast iron, according to our more than ten years Customer tracking survey, under the same working conditions, can extend the service life of the equipment at least ten times more. 3. Light weight Its density is 3.5g/cm3, which is only half of steel, which can greatly reduce the load of equipment.

Application  of alumina ceramic round plate:

1.Mechanical: high bending strength, excellent wear resistance, widely used in tools, ball valves, grinding wheels, ceramic nails, bearings and so on.

2.Electronics, power: high purity alumina ceramics high frequency dielectric loss is small, excellent insulation performance, widely used in transparent alumina ceramics.

3.Medical aspects: good biocompatibility, mechanical properties and chemical stability.
