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.

Meta-Braze 283

Meta-Braze 283 is a free flowing alloy which is suitable for tight fitting joint gaps. This alloy isn’t the most ductile in the group and should be used where a high level of ductility in the brazed joint is not required.

Meta-Braze 281

Meta-Braze 281 provides a good balance between the considerations of the cost, ductility and the flow of the brazing alloy. It is very commonly specified in refrigerated pipework applications, particularly in supermarket installations and is suitable for brazing K65 copper tube for carbon dioxide refrigerated systems.

It is now possible to provide a modified version of this alloy in foil form.

Meta-Braze 386

Meta-Braze 386 is a different type of alloy to the others in this group because it contains tin. 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.
