Meta-Braze™ Silver / Copper Phosphorus Brazing Alloys
Principally used for HVAC&R applications where they are recommended for the flux-less brazing of copper pipes and tubes. Meta-Braze™ 284 can be supplied as a foil which is widely used for electrical engineering applications involving copper. The phosphorus in these alloys imparts a self-fluxing characteristic but also affects the ductility and flow of the product. The products in this range provide different ductility and flow characteristics. They should not be used on nickel or iron containing metals, including all grades of steel, because a brittle joint will result.
