A 4kg single spool of 0.8mm C11 Phosphor Bronze MIG Brazing Wire.  Constructed from 93% Copper (Cu) and 7% Tin (Sn). Manufactured for brazing phosphor bronze, tin bronze, cast iron, gunmetal and the repair of cast copper alloys. Additionally this wire can be used for brazing of ferrous, stainless and dissimilar metals. It can also be used for applying a bearing surface. With many key benefits including excellent corrosion resistance, good electrical conductivity and high strength. Often used shipbuilding and aeronautic industries due to its good corrosion resistance and ability to withstand high temperature exposure.

  • 0.8mm – Available in 4kg and 12.5kg Packs.
  • 1.0mm – Available in 4kg and 12.5kg Packs.
  • 1.2mm – Available in 4kg and 12.5kg Packs.

The main advantages of C11 Phosphor Bronze MIG wire are -:

  • High Tensile Strength  – makes it the ideal option where the finished weld 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 MIG welding wire, these product has an 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.

TYPICAL MECHANICAL PROPERTIESC11 Phosphor Bronze MIG Welding Wire - Mechanical Properties

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, C11 MIG wire also has excellent corrosion resistance making it good for use in corrosive environments.

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.
