De-alloying or Selective Attack in Brazing

When you expose silver-brazed joints to water environments under specific conditions, dezincification of the brazing alloy can take place, leading to joint failure. What is dezincification? What are the influencing factors? Are there solutions? Let’s dive in and discover the answers.

Aluminum Brazing: Corrosive or Non-Corrosive Flux

Many automotive and HVAC/R manufacturers use all-aluminum or mostly aluminum components. When brazing aluminum, two families of fluxes are commercially available: corrosive and non-corrosive. Let’s talk about choosing the proper flux for your application, including the advantages of each.

The Effect of Joint Clearance on Braze Joint Strength

Having trouble with braze joint strength? Check your joint clearance. Brazing uses capillarity to distribute molten filler metal between base metals. When the clearance is narrow and you are brazing with flux, it is difficult for the flux to flow. Capillary action can be inhibited, resulting in reduced strength of the braze alloy. We will explore ideal clearances for various fillers and heating methods, plus base metal properties, joint design and metallurgical interaction.

Step Brazing

Does your process include the challenge of brazing or assembling components with two joints in close proximity—having one joint that cannot run the risk of being remelted due to quality requirements? You may need to resort to step brazing. Join us for a discussion on the applications and alloys involved, along with some common pitfalls and tips for prevention.
