AWS A5.7 ERCuSn6P EN ISO 24373 Cu5180

C11 Phosphor Bronze TIG Brazing Wire 2.4mm 5kg pack.  Constructed from 93% Copper (Cu) and 7% Tin (Sn). Manufactured for joining phosphor bronze, tin bronze, cast iron, gunmetal and the repair of cast copper alloys.  Additionally these rods can be used for brazing of ferrous, stainless and dissimilar metals.  With many key benefits including excellent corrosion resistance, good electrical conductivity and high strength. Often used in shipbuilding and aeronautic industries due to its good corrosion resistance and ability to withstand high temperature exposure. Also, often used in oxy/acetylene welding.


The main advantages of C11 Phosphor Bronze TIG Brazing wire are -:

    • High Tensile Strength  – makes it the ideal option where the finished join must be able to absorb a great of pressure without the risk of compromising integrity and structure.
    • Good Corrosion Resistance – particularly important weld materials may come into contact with corrosive substances on a regular basis e.g. seawater for the shipbuilding industry.
    • Good Electrical Conductivity – as a result of all high copper content TIG welding rods, these rods have excellent capacity to conduct electrical current.

Conforms to industry standards AWS A5.7 ERCuSn6P EN ISO 24373 Cu5180.  The lead free composition makes this product a great environmentally friendly welding wire option.


C11 Phosphor Bronze TIG Welding Wire - Welding Positions


Due to the qualities of C11 Phosphor Bronze TIG brazing wire it is often used in industries such as marine and shipbuilding where corrosion from seawater exposure can be a major factor. Additionally, these rods also have excellent heat resistance which has made them a good choice for the aeronautic industry where high temperatures are often encountered.  Commonly used in oxy/acetylene brazing with materials such as phosphor bronze, cast iron, tin bronze, gunmetal and copper alloys.  While it is not necessary to use Flux Powder, it may be worth considering in situations where the material to be joined is either dirty or oxidised.

C11 Phosphor Bronze TIG Welding Wire - Chemical Analysis

Brazing Vs Welding

The first key difference between brazing and welding is in brazing the base materials being joined are not melted, only the filler wire. Conversely in the welding process the base materials are penetrated. This reason being that during the welding process temperatures reached are higher than the base materials melting point.  In brazing it is the opposite, temperatures reached are lower than the melting point of the base materials thus avoiding penetration.

While there is no need to change the consumables in your torch when brazing or welding, there maybe a requirement for changing the settings on your welding machine e.g. voltage control, wire feed speed and/or gas cylinder settings in order to accommodate any differences encountered when using brazing filler material.


Combining a number of good mechanical properties including excellent tensile strength which refers to a materials ability to withstand high levels of stress and pressure without breaking or deforming.  In addition, other mechanical properties include good yield strength, hardness and ductility.  Moreover, they also have excellent corrosion resistance making them a good for use in corrosive environments.
