Our range of brazing fluxes is available in both powder and paste forms, offering versatility for various applications. Each product is formulated to provide excellent adhesion, reduce oxidation, and improve the overall quality of your joints, ensuring a professional finish every time. From HVAC repairs to industrial manufacturing, our brazing flux helps you achieve durable results in even the most challenging environments.

1. What is brazing flux, and why is it important?

Brazing flux is a chemical compound used during the brazing process to prevent the base metals from oxidising at high temperatures. It helps the filler material flow more smoothly and creates stronger, cleaner joints by removing impurities from the metal surfaces.

2. What types of metals can be used with your brazing flux?

Our brazing fluxes are suitable for use with a variety of metals, including copper, brass, steel, and certain alloys. We offer specific fluxes tailored for different metals to ensure the best results in your brazing projects.

3. How do I choose between powder and paste flux?

Powder flux is typically used for brazing applications where dry or solid forms are preferred, while paste flux is often more convenient for precise application in smaller or intricate areas. The choice depends on the specific requirements of your project. Both types are effective at reducing oxidation and improving brazing joint strength.

4. How should brazing flux be applied?

Brazing flux should be applied to the clean surfaces of the metals being joined, either before heating or during the brazing process. Ensure that the metal surfaces are free from grease, dirt, or oxide layers for optimal results. The flux will activate when heated, protecting the metal and aiding the flow of the filler material.

5. Is brazing flux safe to use?

Brazing flux should be used with care, as the fumes generated during the brazing process can be harmful if inhaled. Always work in a well-ventilated area and use appropriate personal protective equipment (PPE), including gloves, safety glasses, and a mask.

6. How should I store brazing flux to maintain its quality?

Brazing flux should be stored in a cool, dry place, away from moisture and direct sunlight. Make sure the container is tightly sealed when not in use to prevent contamination and preserve its effectiveness.
