Argex Brazing Division

Argex Limited has expanded its range of products to offer a limited, bespoke, range of silver brazing alloys suitable for a range of industrial and technical applications. In offering this range Argex Limited is drawing off its three decades of experience of advising on difficult brazing solutions.

Silver brazing alloys can be utilised in a multitude of differing industries such as HVAC, Automotive, Aviation, Power and Electronics to name but a few. At Argex Limited we aim to be able to supply the perfect brazing solutions for the application required.

Please find below examples of our core industrial brazing range. But please forward any requests for bespoke brazing alloys directly to silver@argex.co.uk.

Argex SBA 55Sn.

This is the ultimate silver brazing alloy in terms of excellent corrosion resistance and fluidity. It is an excellent colour match to stainless steels and is also suitable for joining copper, copper alloys (i.e. brass and bronze) steel (mild and stainless) and nickel and nickel-based alloys. It is suitable for in service operating temperatures of between –150 °C to +150 °C.

Argex SBA 40Sn.

This is the preferred silver brazing alloy for use in the heat exchanger industry (HVAC) for joining ferrous and non- ferrous parent metals (i.e. copper-steel and brass-steel joints). It has good corrosion resistance and fluidity. It is suitable for in service operating temperatures of between –150 °C to +150 °C.

Argex SBA 49 MnNi.

Tool tipping applications require a high degree of brazer skill and specific brazing alloys to facilitate the successful joining of the parent materials with significantly different coefficients of expansion. For this application a nickel containing brazing alloy is preferred as this enhances the ‘wetting’ of the brazing alloy into the tungsten carbide. This specific alloy has an excellent wetting ability and is also useful with hard metals such as high-speed steels, tungsten, tantalum and molybdenum.

Argex SBA 40Ni.

For smaller carbide inserts for the tool tipping industry an alloy which only contains nickel as an addition is usually preferred as this offers improved joint shear strengths.

Brazing Flux.

Argex is able to offer its own specially formulated, technical brazing flux suitable for use with all of the brazing alloys listed above.
