Our in-house turnkey assembly and braze capabilities are ideal for high reliability applications such as feedthrus, heat exchangers, vacuum interrupters, laser assemblies, electrosurgical tools, and waveguides.  These products are typically used within the aerospace, medical, nuclear, communications and energy markets. In addition to conventional metallized ceramic assemblies, we are able to provide highly differentiated Active Braze solutions. This process allows direct bonding of non-metal materials which typically require a metallization layer aiding alloy wetting before ceramic brazing can take place.

Active Brazing by MTC Wesgo Metals provides unique solutions for;

  • Brazing to low density materials
  • Highly corrosive environments
  • Complex joint configurations where metalizing can be cost prohibitive or too challenging to be of consistent high quality
  • Bio-compatible applications
  • High temperature applications up to 1200°C
  • Assemblies with high coefficient of thermal expansion (CTE)
  • Titanium, Zirconia, Macor, SiC and other non-metal materials

MTC Wesgo Metals Active Brazing allows robust joining in a single heat cycle saving time, energy, and decreasing fallout in production.

With our wide experience of combined brazing and alloy development, we have expanded our Active Braze Alloys’ unique features to solve other challenges, such as adding robust thick metallization pads and traces for electrical circuits. The electrical traces can withstand corrosive environments better than traditional inks, while the high-wear contact pads are many times thicker and better wearing than traditional thick film metallization. 

We work closely with our customers using their own designs and helping them with input for manufacturablity. Our experienced engineers will also assist with correct alloy selection and design options for complex joint configurations.

Our extensive facilities encompass vacuum brazing, atmosphere brazing (Hydrogen, Nitrogen, Argon), chemical etching and Helium leak detection. We also offer joint metallurgical analysis reports and cleanroom assembly which includes inspection, brazing and packaging.

Pre Sintered Preforms - PSP Preforms

PSP™ is a customized blend of superalloy and braze powders in either a plate form or specific shape allows selective build-up of worn surfaces to be achieved quickly and efficiently offering savings in time and cost. The porosity of custom performs is less than 2%, so little or no shrinkage occurs–this is a major advantage of MTC Wesgo Metals' PSPs™ over traditional brazing pastes and green tapes.

Active Brazing - Active Braze Alloys

ABA®’s are available in Gold, Silver, Titanium and Copper based materials and offer highly reliable hermetic seal between ceramic and metal for both oxide and non-oxide ceramics. Impurity Limits – All other metallic impurities having a vapor pressure higher than 10-7 mm Hg at 500°C are limited to .002% each. One-step brazing with ABA® replaces metallizing, firing and electroplating, offering savings in time and cost.
