Alumina Ceramic Disc
My factory looking for distributors.
First of all, the lower alumina ceramic sheet is introduced. Alumina ceramic sheet is also called wear-resistant alumina ceramic sheet, high alumina ceramic sheet, wear-resistant ceramic sheet, alumina ceramic patch. Alumina ceramic sheet is mainly made of AL2O3 as raw material, rare metal oxide as solvent and calcined at 1700℃.
Alumina ceramic disc is often used in water resources management, medical treatment, automobiles, telecommunications and household appliances applications.
Product Description:
1.High hardness.
2.High heat resistance: 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
5.High corrosion resistance: it is insoluble in water and only slightly soluble in strong acid and alkaline solutions.
