Brazing, Soldering and Welding Fluxes

Quality joints require flux to protect the joint during
heating and promote complete alloy flow. To ensure the best
connections Harris designed, developed and manufactures
a variety of brazing, soldering and welding fluxes for specific applications.

PRO KNOW HOW

Choosing the right flux.

A chemical flux is commonly used with many braze filler metals. Proper fluxing is important because the flux absorbs oxides formed during heating and promotes the flow of filler metal. Fluxes are chemical mixtures that contain varying chemical components. The mixture is blended to ensure smooth application and adherence.

Ever wonder about the different flux types and where each is used? Here's a crash course that explores the types of silver brazing flux we manufacture.

INDUSTRY EXPERTISE

The world’s first smart flux!

ECO SMART® is a unique, patent-pending flux that is designed with color change technology that lets you know when it is time to braze.
It's boric acid free environmentally friendly formula starts out as a green color that changes to clear when the flux becomes active.
