Silver Brazing Alloys

MAS has an extensive stock of silver brazing alloys, with silver content ranging from 0-56 percent cadmium free rods, both bare and flux coated. This enabling us to offer our customers an “off the shelf” service for delivery to each customer’s requirements.
Silver alloys are used in all the industrial fields where high quality joints between similar or dissimilar metals are required, this is due to their great technical characteristics. These alloys are suitable for all of the common engineering materials with the exception of Aluminium and its associative alloys

MAS is also able to offer any quantity of silver brazing alloys, meaning we can meet the needs of all our customers. Although it is preferred and more common to offer our rods by weight, we will also supply specific quantities if necessary for our customers requirements. Other products that can be also be offered to a specific requirement are: solders, fluxes and torches.
As well as supplying to main line manufacturing we can also offer our smaller specific quantities of silver brazing alloys to model engineers, quantities upon request, either by weight or by rod.

All silver solders are manufactured using virgin metal, including no cadmium, therefore meeting the necessary new international standard ISO 17672. Although cadmium free, MAS still highly recommend that there are good levels of ventilation when in use, this limiting the chances of a build up of fumes from the brazing process.
Safety data sheets are available on all our below products.

Copper Phosphorous Alloys

MAS has an extensive stock of Copper Phosphorous brazing alloys, with silver content ranging from 0-15 percent, enabling us to offer our customers an “off the shelf” service for delivery to each customer’s requirements.

MAS has a stock range of Copper Phosphorus alloys which consists of alloys being, with and without Silver. Their outstanding feature is their ability to braze copper in air without the use of fluxes since, due to the presence of Phosphorus, these alloys have self-fluxing properties when brazing copper to copper. These characteristics are improved by the addition of Silver.

These alloys however are unsuitable for brazing Nickel, Nickel-based alloys, ferrous metals and copper alloys containing Nickel and Iron. The brazed joints will become inherently brittle due to the formation of inter-metallic compounds. Lower grade phosphorous alloys are recommended for when optimal mechanical strength or resistance to a vibration is required.

All products are manufactured using virgin metal, therefore meeting the necessary new international standard ISO 17672. MAS still highly recommend that there are good levels of ventilation when in use, this limiting the chances of a build up of fumes from the brazing process.

Data sheets for all the above are available when necessary.

Soft Solder

MAS soft solder is manufactured from a grade of solder alloy with purity levels far exceeding the requirements of all national and international standards. All of MAS’s soft solder wires are High Purity Solder Alloys, using the finest virgin materials available world-wide.

Soft soldering is typically used when working in electronics, plumbing, or the assembly of sheet metal parts.
We sell our soft solders as followed in the table below:

MAS also supply the relevant fluxes for the above products

Fluxes

MAS stock a wide range of Fluxes in different forms such as powder, paste, cream, gel and liquid, specially formulated to obtain perfect and clean joints due to their high quality.

The objective and purpose of the Fluxing in the brazing and welding processes is to prevent the formation, dissolve or facilitate the removal of the oxides or any other undesirable substances from the surfaces to be joined. Another fundamental objective of Fluxes is to assure the formation of a perfect brazed joint by protecting the base filler metal from oxidation and to reduce surface tension, allowing a free and perfect flow of the filler alloys.

The selection of the most appropriate flux must be done according to several indications and it is always recommended to choose the right product after a careful evaluation of all the different factors.
The table below shows the range of MAS fluxes, as well as the melting range the fluxes have:
