A comprehensive evaluation of the brazing process is necessary to improve results.

Braze quality consists of three interrelated concepts:

1. Establishing and documenting a brazing procedure
2. Understanding and applying correct braze principles
3. Post-braze inspection Guidelines

HARRIS                                        ALUXCOR ALUMINUM FLUX

Harris Aluxcor aluminum brazing alloys offer excellent strength and corrosion resistance for joining aluminum-to aluminum or aluminum-to-copper or brass. Aluxcor is free flowing with unequaled capillary attraction, ductility, and penetration.

Our ALUXCOR zinc aluminum alloys also have non-corrosive and non-hygroscopic cesium flux with a lower melting temperature and wider melting range than aluminum silicon alloys.

ALUXCOR 4047 has four different non-corrosive and non-hygroscopic flux combinations with no binder to fit your customer specific heating applications. The different formulas flux’s release at increasing speeds in order from 15.1 being the slowest, to 15.4 being the fastest. The 15.3 formula is our most common for hand brazing applications but Harris now offers different formulas to best optimize flux release in controlled auto brazing heat applications.

Pro Know How

What you need to know about soldering

Soldering is a joining process similar to brazing but occurs at a lower temperature, typically below 800°F, using a non-ferrous filler metal with a melting point below that of the base metal. The metals to be soldered dictate the flux, solder, and heating methods to be used. To achieve a sound soldered joint several factors should be considered.
