Stop-Off Blog

Stop-Off: Controlling the Flow of Alloy In brazing, we focus much importance on cleaning parts to remove oils, dirt, and oxides. This is because braze alloy will not flow over areas not properly cleaned, and the quality of the braze joint will be compromised. BUT, what about situations where you DO NOT want alloy to flow or bond? Because of aesthetics, tolerances, or subsequent assembly steps, you sometimes need the flow of braze alloy to be contained or redirected—to STOP flowing or to stay OFF a surface. Examples include precise designs involving threads or holes. Read on for a discussion about the unique product called Stop-Off.

Interfacial Corrosion

Interfacial Corrosion The situation: When brazing stainless steel with flux, subject to a damp environment, you notice rust-like spots around the periphery of the braze metal. Rapid corrosion may begin within two days or even as soon as two hours. The brazing filler metal may eventually peel away from the stainless steel surface. Ultimately, complete separation of the filler metal from the stainless steel may occur, resulting in complete failure. Why does this happen? How can the problem be avoided? Join us for a discussion on the science behind this issue and the solutions that help avoid interfacial corrosion.
