Copper Rod

With its uniform high electrical conductivity Taalay Copper Rod ensures the highest possible efficiency in converting and transmitting electrical power. Whether as a conductor in underground and submarine cables or as enameled wire in transformers, generators and motors: its uniform high quality and purity mean that our rod is much sought after for these demanding applications. At the same time, excellent fine drawing properties, the uniform recrystallization behavior and the surface structure of our rod, which is particularly important to the makers of enameled wire, considerably simplify further processing by our customers.

In signal transmission and electronics, too, the very good physical and chemical properties of our products are extremely useful in assisting in continued miniaturization and weight reduction while maintaining the utmost reliability.

Production / Quality

Production

Cathodes and Mill Berry Scrap, which have a copper content of more than 99.95 %, are first melted down in a carefully monitored process and then cast continuously as an endless bar.

Still glowing, this bar is then fed into the hot-rolling mill where it is rolled into copper rod. This is followed by surface conservation before the rod is laid into coils weighing up to 5 ton each. Sampling, packing and labelling complete the production process. This efficient, energy-optimized and environmentally friendly continuous casting process is constantly being perfected and used by Taalay.

Quality

Every coil manufactured undergoes intensive testing by an independent department. Integrated “in-line” procedures are constantly on the look-out for surface defects and magnetizable inclusions.

At the same time, all the relevant parameters of the production process are monitored, documented and used for the detailed assessment of the products’ quality. Independently of this, two rod samples are taken from each coil, which are then used for destructive testing: properties such as electrical conductivity, surface, quality of the microstructure, tensile strength, chemical composition and recrystallization behavior are determined and compared with fixed target values. Only if the rod meets the defined criteria in every respect is it released for dispatch.
