The Right Flux for the Job High-temperature fluxes are used with brazing filler materials having melting temperatures of 1600°F (870°C) - 2000°F (1100°C), or 2200°F (1205°C) for boron-modified filler. These fluxes are useful for applications where higher-temperature alloys are needed for strength, ...

Flux is a chemical compound applied to the joint surfaces before brazing. Watch our new technical video for an in-depth look at the four functions of flux: 1. Protect from oxygen 2. Dissolve & absorb oxides 3. Help filler flow 4. Indicate temperature Then, we'll show you how Handy® Flux appears ...

How Stop-Off Works To understanding how Stop-Off works, let's review the brazing process. At Lucas Milhaupt, we preach six fundamentals of brazing: 1. Good fit & clearance 2. Clean metals 3. Uniform fluxing 4. Proper assembly 5. Brazing technique 6. Post-braze cleaning Let's focus on Step 2 - ...

In about four minutes, this new technical video from Lucas-Milhaupt will walk you step-by-step through this brazing process. We'll address procedures and alloy options that will help you successfully braze copper and aluminum components. Watch for the definition of a perfect joint gap! We'll share ...

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 ...

Traditional Braze Alloy and Flux Paste vs. Flux-cored Brazing Products In less than five minutes, this technical video clip below from Lucas-Milhaupt will show you the Handy® way to improve your process for brazing copper to steel. Handy One® flux-cored products offer these benefits: No separate ...

Welcome to our first video of 2013, featuring capillarity. We know the importance of capillary action in the brazing process. This scientific phenomenon allows molten alloy to be drawn into the joint between two metal parts. Our three-minute video will show you what capillary action is and how it ...

AWS Specifications and Classifications The American Welding Society (AWS) is a nonprofit organization whose purpose is to support the growth of knowledge and technological advances in the field of brazing and other forms of metal joining. They have put into place a list of standards and ...

Importance of Ring Volume One factor that may impact the strength of a brazed joint is the depth of alloy penetration into the joint. If an operator does not apply enough alloy to the assembly, the final part will not have the ideal strength and/or leak tightness characteristics for a brazed joint. ...

Reducing Alloy Consumption The use of flux-cored braze products (both in wire feed and ring form) can significantly reduce the alloy consumption for each braze joint. Lucas-Milhaupt Handy One® silver brazing products are an industry staple, improving manufacturing processes and cost containment for ...
