Industry Pink Mo Mn Metallized Ceramic Body Refractory for Electronics
We use thick and thin-film technologies in our refractory metallising, depositing proprietary coating to our ceramic components according to different customers' specifications.
Utilizing a coating of molybdenum - manganese (Mo - Mn) based paints followed by nickel plating, tungsten paints followed by gold plating, afterward, an interface can be formed that helps to achieve ceramic to metal jointing by means of brazing with hermetically sealed. The typical thickness of Mo -Mn is 10 to 40 um after sintering, but the thickness of Au plating will be much thinner as 0.5um.
● Ceramic body + Silver (Ag) plating
● Ceramic body + Molybdenum-Manganese ( Mo-Mn) metallization
● Ceramic body + Molybdenum-Manganese ( Mo-Mn) metallization + Nickle ( Ni ) plating
● Ceramic body + Tungsten ( W ) metallization + Gold ( Au ) plating
Special types are available according to customer's drawings or samples
● Min. electric resistance and vacuum tightness, and less than 1×10-11 Pa•m3 / s
● High bonding/brazing strength, It can be up to 150 MPa after brazing
● High mechanical strength, flexural strength can be up to 338 MPa
● High insulation, anti-chemical and anti-aging. It will be free of rust forever
