Meta-Braze™ 286
Meta-Braze™ 286 is the eutectic composition for Ag-Cu-P and provides a low-melting, free-flowing alloy. The uses for this product are however limited.
Silver / Copper Phos Braze Alloys
Meta-Braze™ 284 Foil for Electrical Applications
Meta-Braze™ 284 foil is available from stock and is suitable for electrical engineering applications such as electric motors, switchgear. electrical contacts and lightening conductors.
Product Uses and Applications
The Meta-Braze™ silver / copper phosphorus product range provides a highly reliable solution for flux-less brazing in HVAC&R and electrical engineering applications. Brazing engineers have to be confident in the quality of the braze rod they are using every time they make a joint. This is particularly true for flux-less brazing of copper pipes and tubes for refrigeration, air-conditioning and medical gas pipework. Meta-Braze™ silver / copper phosphorus brazing alloys can be relied upon to flow consistently every time.

It is very free flowing and forms smooth neat fillets but is also not especially ductile. It requires a flux and is suitable for use where there is a need to join copper alloy parts which need a very smooth looking joint with a narrow joint gap. Product Forms× | ||
