At the cutting edge of technology in the manufacture of copper alloys products, Lebronze alloys retains its European leadership with more than 35 million caps produced and sold every year to almost every car builder worldwide, directly or indirectly throughout our distributor network.

We can answer all your requirements, from welding electrodes (spot welding electrodes or resistance welding electrodes) to the copper electrodes and from the smallest quantities of very specific electrodes to the largest volumes of cold formed electrodes.

We manufacture and supply male and female spot welding electrodes, caps, round bars, flat bars, plates, welding wheels and any kind of engineered part mainly from copper alloys.

Our group, is the only fully integrated manufacturer (casting, extrusion, cold forming, machining, stamping), with an indisputable advantage: we manufacture our own alloys to produce electrodes. This assures continuous quality and full traceability.
