Flexible busbars

Flexible busbars are mostly used in the manufacturing industries, like e.g. in the energy and more recently in automotive industry to transport current between components, where high flexibility is required. Industrials may also use aluminium flexible busbars because of the weight and costs reduction.


Flexible busbars are traditionally in copper and welded by diffusion welding, applying high current and pressure over a long time. They offer excellent mechanical and electrical properties.

They are produced by stacking several strips of metals on each others and are an alternative solution to copper braids.


Flexible busbars offer a number of advantages over traditional busbars :


  • Flexibility : Flexible busbars can be bent and drilled, making them easier to install in tight spaces or for applications requiring changes of direction.
  • Weight reduction : Flexible busbars are lighter than traditional busbars, making them easier to handle and install.
  • Vibration reduction : Flexible busbars are more resistant to vibration than traditional busbars, making them more suitable for applications where vibration is present.

Aluminium flexible busbar laser welded


TECHNAX welds flexbusbars by resistance welding, which is faster and much more industrial than diffusion welding.

We offer complete solutions in the fabrication of flexbusbars. Starting from a coil, the metal strip is unwound and cut to length to obtain strips.

In a next step, copper strips are stacked and welded on their extremities, by resistance. Finally, strips are calibrated, sometimes bent and/or punched.

TECHNAX recently developed expertise in the fabrication of aluminium flexbusbars, using the laser welding technology.

By using the TECHNAX concept, flexbusbars can be produced in a matter of seconds. Our solutions also offer the advantage of considerably reducing wear parts compared to traditional solutions.
