With the advances in technology today, you would think that joining ceramic to metal would be an easy process, however, as Keith Ferguson, Business Development Manager from Morgan Technical Ceramics Wesgo Metals explains, it is a little more tricky than that!

Successful ceramic-to-metal brazing requires careful attention to joint design fit up at braze temperature, and CTE mismatch considerations. Traditional atmosphere brazing with moly-manganese metallization of ceramics as a first step, would require a matching paint for the ceramic and several process steps, whereas using our active brazing process only requires one step. Beyond successful joining, some applications require the brazed seal to be vacuum tight or require a pressure test to prove it is successful for the end use.

Traditionally the brazing of technical ceramics has always involved Alumina, however active brazing, done at MTC Wesgo Metals utilizes a different process which allows strong bonds to virtually all the technical ceramics, and with fewer steps. We use our active brazing process to manufacture products such as sensors, RF powertubes, x-ray tubes, electrosurgical tools, implantable devices, heat sinks, gas turbine components, waveguides for industries such as medical, oil & gas, energy and aerospace.

We developed the active brazing process, and have been producing the alloys for decades. We are vertically integrated in alloy production from pour to final component making us uniquely qualified to take on critical brazing projects.

It also helps being part of Morgan Technical Ceramics as we can access a wide variety of materials and we work with our colleagues all over the world developing custom solutions for our customers. With this much vertical integration, we provide solutions others can’t offer.
