Product Description:
Electrical Insulation Al2O3 Alumina Ceramic Sheet / Plate
Alumina based ceramics are by far the largest range of advanced ceramics made by UNIPRETEC Ceramics. Due to the important combination of properties, we have thoroughly researched the behaviour and characteristics of our Alumina products to give you the best possible component. Typical Alumina characteristics include:
- Good strength and stiffness;
- Good hardness and wear resistance;
- Good corrosion resistance;
- Good thermal stability;
- Excellent dielectric properties;
- Low dielectric constant;
- Low loss tangent...
Alumina Ceramic Plate Advantage:
1.High purity: 99.7% alumina purity make sure high working temperature.
2. We can make very tight tolerance by machnning, surface polishing and glazing are available.
3.Very small and very big sized ones can be made.
4. Inspection: each single plate will be checked before shipping.
5.Low transportation cost: We have long time cooperated shipping agency, which can provide very low prices.
Properties Sheet:
The products are made of high purity zirconia ceramic and alumina ceramic material, which have
advanced and excellent performances, fabulously popular.
