Continuous Cast Copper Wire Rod – Aurubis ROD and RheinROD
Aurubis ROD | RheinROD is a cast and rolled oxygen-bearing copper wire rod from Aurubis. With its extremely high electrical conductivity, Aurubis ROD ensures the highest possible efficiency in converting and transmitting electrical energy and signals. Other excellent features such as outstanding drawability, uniform recrystallization behavior and excellent surfaces make our wire rod ideally suited for use in demanding processing methods and applications. The basis of these characteristic features of Aurubis ROD | RheinROD is not only its high chemical purity – a result of using cathodes that clearly exceed the LME Grade A quality standard – but also the state-of-the-art production technology at our four ROD plants.
Basis for sophisticated applications
Almost every copper wire – and thus almost every cable or enameled wire – starts out as wire rod, making it the most common copper intermediate in the world. About 75 % of global copper cathode production is processed into continuous cast wire rod. Depending on their intended use, copper wires must meet varying requirements which must be considered when determining the quality of the wire rod. Aurubis supplies the right quality for each application, customer and intended use.
Aurubis ROD | RheinROD is the ideal starting product for further processing by drawing or rolling. The combination of outstanding conductivity and formability makes our ROD the perfect choice for copper wires in various types of cables for infrastructure and enameled copper wires in electrical engineering.
The excellent surface quality of our wire rod, mainly created by production at our four ROD plants, is a basic requirement for high temperature-resistant, error-free insulation systems. For this reason, our production and quality control specialists make surface quality a top priority.
