Oxyfuel Gas Welding (OAW)

The important advantage of Stay-Brite® solders is the greater strength of the overall component. After joining, its lower working temperature eliminates the weakening of the base metals caused by annealment from high brazing heat. The result is a stronger, more economical joint.

Stay-Brite® silver bearing solders have the same excellent affinity as SafetySilv® alloys for bonding with most of the ferrous and nonferrous alloys (including stainless steel, nickel, copper, brass, etc.) It provides a considerably higher than necessary elongation for sound dissimilar metal joints and vibration applications.

Stay-Brite® alloys range in temperature from 430°F to 535°F. Stay-Brite® solder eliminates oxide scale formed from brazing heat. No nitrogen purge is required for HVAC/R tubes. They are cadmium free and nontoxic. Stay-Brite® is a eutectic alloy with a single melting point of 430°F (221°C).

Specifications:

The Harris Al-Solder 500 aluminum solder & flux kit for torch or iron is used all solder-able alloys to each other and to dissimilar metals. Also for zinc die-cast. Forms excellent, corrosion resistant joints on the tough to solder aluminum alloys. Also beneficial as a high temperature solder on most other metals. Not recommended for magnesium.

Forms excellent corrosion resistant joints on the tough-to-solder aluminum alloys. Joins all solder-able aluminum alloys to each other and to dissimilar metals, both ferrous and nonferrous. Also beneficial as a high temperature solder on most other metals.

Procedure:

1. Clean the area to be soldered
2. Apply Stay Clean aluminum flux
3. If using an open flame, heat indirectly with the torch in motion (do not direct the torch on the flux)
4. Heat until the flux becomes a nut brown color
5. Apply the alloy
6. Discontinue heat as soon as flow
7. Allow to cool. Remove flux residue with wire brush and hot water

Features:

·         Tensile strength – Up to 20,000 PSI

·         Solidus – 391ºF

·         Liquidus – 482ºF

·         Good color match on aluminum and zinc die cast
