Connector Strip

Aurubis supplies a large selection of strip of high uniform quality with the narrowest tolerances and homogenous product qualities according to customers' specifications and applications.

Aurubis offers high-quality connector strip with standard copper, copper alloys and High Performance Alloys (HPAs). The extensive portfolio includes bare and tin-coated surfaces* to the highest standards in the industry (*as coils, traverse wound and as ContiCoil®).


Connector strip is the pre-material for stamped grid products and connector applications such as automobiles, mobile phones, laptops, tablets, housing, medical instruments, industrial equipment and many other applications requiring the transfer of electricity, signals or power in a wide variety of industrial and consumer products.


On the one hand, connectors need to be easy to insert and remove for assembly, but on the other hand, they need to be corrosion-resistant to ensure a long-lasting connection for the components.


In order to meet the constantly increasing demands on connectors and stamped grids – such as low insertion forces, good corrosion resistance and good solderability – in very complex electrical and electronics systems such as modern vehicles, and as a result of the miniaturization trend, the strip used is required to have repeated surface treatments.
