● High mechanical strength, insulation strength up to 18KV/mm at D•C
● Anti-chemical, anti-aging without corrosion and free of rust forever 

● Super wear resistance with long service life

Description of metalized ceramic insulator:

The metallization of alumina ceramics (min. 94.4% alumina) was performed by the molybdenum-manganese process in hydrogen and nitrogen reduced atmosphere under 1250℃ ~1450℃ cured. After the sintering, the metallic coating will adhere to the ceramic part, the typical metallized layers consist of tungsten as well besides for Mo/Mn. In order to enhance the brazing effect, certain electroplating will be covered by metallization layers, such as nickel, silver or glad plating, then the metallized ceramics can achieve ceramic to metal, ceramic to ceramic joining application well.

Jointing type of metallization

● Ceramic base + Molybdenum-Manganese ( Mo - Mn) metallization,   20 ~ 40um thick

● Ceramic base + Silver ( Ag) plating,   2~ 4um thick

● Ceramic base + Molybdenum-Manganese (Mo - Mn) + Nickle (Ni) plating, Mo/Mn: 20 ~ 40um thick, Ni: 2~6um thick

● Ceramic base + Tungsten ( W) + Gold (Au) plating, W: 20~40um thick, Au:  0.5um thick
