Expertise Metal brazes

Brazing of metal for joining ceramic is one of Kyocera's core competences

Metal brazes in ceramic-metal composite components enable complex solutions

Physical-technical applications impose high requirements on the materials used. The outstanding properties of our ceramic-metal composite components such as excellent hardness, extremely tight seals, good wear properties, corrosion resistance, low density and good electrical insulation properties are optimally designed for the challenges of a wide variety of applications. Our many years of experience as a manufacturer of prototypes and standard components guarantee our customers superb solutions to a wide variety of challenges.

 

For the production of ceramic-metal composite components, high-purity brazes are used for bonding metallized ceramics to metal components. The brazes are matched with the prevailing technical requirements using decades of experience. Cost-efficient, high-quality silver-copper brazes that meet DIN 17672 are used to wet metal alloys with adapted thermal expansion and thus enable extremely tight bonds with high strength and simultaneous temperature load.

 

For ceramic bonds with stainless steel, molybdenum and many other special materials, palladium-containing and gold-based brazes are also used, which enable these materials to be wetted, and making them extremely resistant to corrosion. Special brazes with adapted melting ranges for special requirements and requests from our customers are also developed and manufactured individually.

 

For certain bonds, so-called active brazes can also be used, which enable ceramic to be brazed directly to the metal without the ceramic having to be metallized beforehand. Active brazes contain titanium or other active elements that react with the ceramic and thus enable brazing.

 

We have brazes for almost any application and we use the appropriate type and precisely the right amount for each one. In particular, we process wires, foils, moulded parts and pastes. Our qualified braze suppliers meet the highest quality requirements for vacuum suitability according to the standard. Each new batch is released for use in production after a complex internal test procedure. This enables us to offer our customers extremely high, constant quality and process reliability in their respective applications.
