Specialty Wire and Bars

In addition to round, square, (and) hexagonal wires and-bars 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.
