Specialty Wire

In addition to round, square and hexagonal wires with a broad range of dimensions, Aurubis manufactures a large selection of special profiles for processors of sophisticated precision parts.

Customers benefit from a diverse portfolio of alloys and dimensions of drawn products from Aurubis. Delivery options on spools, in drums, as packaged coils or ring material provide a large selection of coil types and processing weights.


Blue Brass®: Lead-free. Machinable. Conductive.


Under the BlueBrass® brand name, Aurubis Stolberg is developing an alloy family that excellently combines the current standards in terms of machinability and cost-effectiveness with the increasing demand for lead-free products.

All alloys in the BlueBrass® family meet the requirements of the EU directives on lead-free products.

All BlueBrass® alloys are individually adapted to the customer's product and process requirements.

BlueBrass® is available as semi-finished strip and wire, as well as in rod format.

In addition to its strength, this alloy’s formability is much higher than brass alloys containing lead, to an extent that was previously only possible with lead-free alloys with poor machinability.
