We developed the bercoweld® series for brazing and welding copper and copper alloys. Our complex range of wire electrodes for brazing and welding provides the right product for every application.

bercoweld® wires for brazing and welding currently comprises more than 20 alloys of the following material groups:

  • Low-alloy copper alloys
  • Tin bronzes
  • Aluminum bronzes
  • Copper-nickel alloys
  • Special alloys

    Advantages of bercoweld® wires for brazing and welding

    bercoweld® wires for brazing and welding offers significant advantages. The automotive industry has impressively demonstrated how galvanized sheets can be joined with copper wire without the need for costly reworking. Here, so-called tailored blanks, tailor-made components made from thin sheets of different qualities are laser, hard or high-temperature brazed with bercoweld®. Subsequent treatment and galvanizing of the joint seam are no longer necessary, but the corrosion protection remains intact. This allows enormous cost and energy savings. The advantages of brazing with copper alloys at a glance:

    • Optimal gap bridging
    • Low joining temperatures
    • Low energy consumption
    • Low heat penetration reduces distortion of the base material
    • No galvanizing of the joint required

    In terms of numbers, working with copper brazing wires can result in savings of up to 30 percent in manufacturing costs compared to conventional steel wires. We can look similarly at energy demand: The savings potential here is up to 20 percent. In the context of rising energy prices, in particular due to the imminent taxation of CO2emissions, this area is of particular importance.

    bercoweld® brazing and welding wires are available in all common designs: Spools (plastic or wire basket), barrels, rods, and rings. Upon request, rods are also available in embossed versions – even in the smallest batch sizes and in special alloys according to customer requirements.

    With the innovative bedrabox you can further increase your productivity. If you opt for bercoweld® from the innovative bedrabox, the high filling quantity and continuous wire run-off speed mean that the time-consuming work of changing spools is no longer necessary. So downtimes in production can be enormously reduced.

    3D printing with bercoweld® brazing and welding wire

    3D printing, also known as additive manufacturing, offers unprecedented possibilities and great savings potential. This enables the individual and flexible production of components with completely new forms and functionalities without any loss of material as with classic manufacturing processes. 

    Our high-alloy aluminium bronzes are particularly suitable for 3D printing and deliver proven bercoweld® advantages of corrosion resistance and a high basic material hardness:

    Due to our own foundry and many years of expertise in the development of new copper-based materials, it is also possible for us to develop new materials far removed from the current product portfolios at any time.
