Product Description

High Purity Alumina Metalized Ceramic Base with Gold Plating for Electrical Coil

1. This metallized ceramic base is made of 95% or 99% aluminum oxide ceramics which has superb mechanical, electrical thermal properties.

2. The metallic layer will be applied to a certain surface of ceramic parts which cured by high temperature, then the metallic layer will adhere the section tightly to achieve ceramic to ceramic, ceramic to metal jointing. 

3. 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 

Main features of metallized ceramic insulators:

● High bonding/brazing strength                                   ● Min. electric resistance and vacuum tightness           

● High mechanical strength, insulation strength           ● Anti-chemical, anti-aging without corrosion             

● Super wear resistance with long service life
Key performance parameters of metallized ceramics

Leak rate

≤1×10-11 Pa•m3 / s Metal layer tensile strength ≥ 150Mpa

Volume resistivity

≥108Ω•cm CTE (6.5 ~ 8.0) × 10-6 /°C

Insulation strength
