Aliaxis Utilities & Industry Ceramics Division

For the most extreme offshore and subsea conditions we can provide you with custom-made solutions fitted to your special purposes. Whether you have problems with corrosive environment, high pressure, high abrasion, extreme erosion, high temperature or steep temperature changes, our FRIALIT ceramics can be a solution.

During the years, we have developed technologies for production of ceramic-to-metal assemblies. We can call ourselves specialists in connecting ceramics to metals, where metal parts are strengthened by the ceramics in zones exposed to abrasion, erosion and corrosion. Various connecting methods have been mastered, such as shrinking in, soldering, brazing, gluing and sintering in. By wrapping ceramics in metal, the fear of thrust and fracture vulnerability with ceramics will decrease considerably.

Ceramic electrical feedthroughs, connectors and insulators

Aliaxis Utilities & Industry / Friatec manufactures a wide variety of ceramic-to-metal seals for use as electrical feedthroughs and connectors. Our ceramic feedthroughs are designed to operate under high pressure together with high voltage, high power and high temperature in corrosive environments.

Our feedthroughs can be produced with one or more pins, a ceramic insulator and a metal housing, all brazed together to make a hermetically sealed electrical feedthrough or connector. The ceramic insulator consists of our highly insulating 99,7% aluminium oxide FRIALIT F99,7. Depending on the application parameters and if required any of our other ceramic materials may be used.

According to your application parameters we will carefully find the right material combination of our ceramics together with the best suited metals, layers and alloys. We use highly insulating ceramics of the utmost quality in our components. Our experienced teams in the assembly development and design departments have the required know-how and experience in connecting ceramics to various metals with different brazing technologies.

Our ceramic-to-metal assemblies are suitable in numerous applications including subsea systems, high-pressure oil systems, vacuum systems, and instrument systems where you have pressure up to 2,000 bar.

Ceramic components for sensors

We manufacture high-quality parts made from FRIALIT-DEGUSSIT ceramics for applications involving complex and demanding requirements. Sensor technology is an interesting, ever growing area often requiring the use of ceramics. To mention a few:

• Ceramic components for pressure sensors and pressure transducers
• Microwaves and radar sensors for contact free measurements as well as for interface measurement
• Magnetically inductive flow meters
• Capacitive sensors for level gauging systems used for pressure ranges of more than 1,000 bar

The particular features of the ceramic materials by FRIALIT-DEGUSSIT for sensors are:

• Small as well as large product dimensions
• Low hysteresis of the measuring signals up to the range of 0.05% resulting in high reproducibility of the measuring results
• Great natural stability
• High resistance to corrosive, erosive and abrasive attack
• Suitable for high pressure usage
• High temperature resistance

We achieve optimum and reliable problem solutions through continual development of materials and products in close co-operation with our customers.
