Copper-Phosphorous Brazing Rods – LOMYPHOS

More informationGet a quote

Copper-Phosphorus brazing rods, known as Lomyphos, are widely used today for a variety of assembly operations. They are dedicated to “hard” brazing and are used in a variety of applications. Lomyphos copper-phosphorus brazing rods are distinguished by their composition and melting temperature. Metaconcept is the place to get them.

Copper-Phosphorus Brazing Rods: A Versatile Solution

Lomyphos is a rod made from copper and phosphorus. It has solidus/liquidus temperatures of between 710°C and 805°C. Lower temperatures can be achieved by adding silver to the alloy. Adding 2% cadmium-free silver, for example, produces rods with solidus/liquidus temperatures between 650°C and 800°C.

Copper-Phosphorus-Lomyphos brazing rods are mistakenly called “false brazing rods”. In fact, “false” should be spelt “phos”, the abbreviation for phosphorus. For practical reasons, it would be more appropriate to use the name “Lomyphos”. Whatever its composition, this type of rod ensures good castability.

Copper-Phosphorus – Lomyphos brazing rods are a versatile solution for brazing. They are ideal for brazing copper, brass and bronze. You can also use them to braze sanitary and central heating pipes. They are used in a variety of sectors, including construction, mechanical and electrical assembly, plumbing, etc. Lomyphos come in a variety of forms: bare or coated rods, cored or bare wire, laminates and tapes.

Advantages of LOMYPHOS Rods for Quality Assemblies

Are you concerned about the quality and strength of your joints? If so, choose Lomyphos copper-phosphorus brazing rods made by Metaconcept. Our products are made from quality materials that come from recycling processes. Our “false soldering rods” enable you to ensure the quality of your soldering and carry out your work to the highest standards.

You can use our copper-phosphorus alloy filler metal on copper without having to use a stripper. This is due to the presence of phosphorus, an element that has anti-stripping properties on copper. Since you no longer have to use a stripper, your safety is optimised. It should be pointed out that to braze certain base metals, you need to apply a stripper. This is the case, for example, when assembling copper alloy parts. In this case, you need to use an external stripper or a rod coating.

The other advantage of copper-phosphorus alloy rods is that they are easy to apply and handle. They also enable you to carry out brazing in compliance with the requirements of the standards.

Use and Brazing Techniques with Copper-phosphorus Rods – LOMYPHOS

LOMYPHOS copper phosphorus rods are easy to use. To braze, first clean the areas to be joined with a workshop roller or steel wool pad. Once this is done, apply the stripper. As mentioned above, this depends on the nature of the metals or alloys to be joined. Next, fit the parts to be joined together and run the flame over them several times to heat the surface. Then apply the rod so that it melts. When a ring forms at the base of the joint, remove the copper and phosphorous filler metal. Wait for the metals to cool before removing the residue with a damp cloth. Please note that the “false brazing rod” cannot be used on nickel alloys, ferrous metals or copper alloys containing nickel.
