Leading expert in wire manufacture
Aerumtec GmbH has many years of experience with the manufacture of wire products, the origins of which can be traced back to 1570 with the so-called Lyonese Wares (fine wire products made of copper and copper alloys). With the production of shiny gold and silver wire and the finest metal mesh, the company laid the foundations for a successful history.
In the 1920s, the first wires and round strands were produced for the rapidly growing electrical industry. Since the end of 2023 – after the spin-off from LEONI AG – Aerumtec has been an independent company and one of the market leaders for high-quality copper wire and technically sophisticated copper applications.
Our product range includes wires, strands, braids and ropes made of copper, electroplated copper, Histral® alloys and special materials that are both robust and flexible, as well as prefabricated wire solutions. We also develop innovative products for customer-specific applications.
Thanks to our extensive know-how and many years of experience in wire manufacture, we are able to meet the diverse requirements of various industries. Aerumtec’s main customers can be found in attractive and dynamic sectors such as the automotive industry (including e-mobility), aerospace, industrial applications, data communication, medical applications and renewable energies.
