High thermal conductivity ceramics we metallize and braze: beryllium oxide (BeO) & aluminum nitride (AlN)

Metallization & Brazing for BeO & AlN

Careful selection of metalizing paints is required during this process since high temperatures will affect the diffusion of metals that can degrade metallization adhesion strength at operating temperatures above 1100°C. In a hermetic braze application, careful selection of the right paint and braze alloy can make the difference between a successful bond and one that will suffer early failure via vacuum leaks or adhesion failure. Elcon manufactures custom paints with a 25-year history of reliably performing at elevated temperatures. Our unique capabilities allow us to turn around high-quality, leak-free parts both quickly and affordably for clients around the world.
