Weight saving

A key challenge for LEONI

The number of functions in the vehicle is steadily increasing, at the same time the total weight should not increase. The lightweight construction is a key challenge for us. The use of alternative materials to copper conductor makes all the difference here. Especially aluminium is a relevant key factor. The variety of contact designs for aluminium cables is far greater than that of copper wires.

Whether aluminium specific contact parts with altered crimp geometries and different crimp zones or sono crimp technique – a combination of crimping and ultrasonic welding – our aluminium cables connect reliably every contact technology.
