Research and Development

The Research and Development (R&D) division develops projects related to innovative topics for the Aurubis Group and works on sustainable process and product improvements.

Innovations from our Research, Development and Innovation division are very significant for us, as they help to secure our economic future. Our international team of 56 highly qualified employees from different fields develops successful innovations – together with internal and external partners.

Environmental protection is a key driver of our R&D strategy. The consideration of current and future environmental standards, a resource-efficient approach to raw materials, water and energy, and the continuous reduction of emissions are important targets in this respect. One example of a reaction to future environmental demands is the research in primary and secondary metallurgical slags, which we continued.

Examples of our work in R&D and Innovation

Excellent properties: “BlueBrass 42” at Aurubis Stolberg
When developing innovations, we also utilize our close contact with our customers to orient our R&D work to the demands of the market. One example can be found at Aurubis Stolberg. The site has developed the “BlueBrass 42” family of alloys, which combines the current standards of the electrical and automotive industries in terms of conductivity, machinability and formability with the increasing demand for lead-free products. There was a breakthrough towards series fabrication for key customers during the reporting period.

High-performance copper-bearing alloys: "Alloyed Wire"
In the “Alloyed Wire” project, we made progress in the fabrication of high-performance alloys made of wire with high copper contents. This top-quality wire is exceedingly stable with high electrical conductivity. It is used as a base material for connectors, press-in contacts and electrical conductors with special demands. These materials are also used in safety applications in cars, e.g. airbags and ABS. Nevertheless, additional process developments are necessary before a stable series production is possible. In the strip sector, the introduction of a high-performance alloy that is used to produce connectors was successfully concluded. The special feature is once again the good combination of strength and conductivity, paired with above-average resistance to softening at higher temperatures. The alloy is used in the automotive sector, among others. In addition to casting the alloy, production trials up to the initial sampling stage were successfully carried out with key automotive suppliers.
