Signal cables based on copper alloys for applications in the automotive sector

Using alternative materials in signal cables is a development leading to significant weight reductions in automotive applications, thereby rendering an important contribution to the husbanding of resources as well.

Will REACh regulations mean the end of the line for cadmium?

On 20th June 2013 the ECHA (European Chemicals Agency) published the latest list of substances of very high concern. In this update six new substances were added to the list, including cadmium (7440-43-9) which is still used today in a number of applications in the cable industry.  REACh therefore now imposes a requirement on suppliers to inform and notify customers regarding the use of cadmium.  In the long term in all applications cadmium will be replaced by other materials.

CU-ETP and CU-OF

At LEONI, we use two different types of copper (Cu) for electrical conductors:

  • ETP Cu (Copper electrolytic tough pitch, i.e. containing oxygen)
  • OFHC Cu (oxygen-free copper) for special applications

What are the differences between these two materials and which applications are they used for?

Flex Life

“Flex Life” – in German “Biegewechselfestigkeit” (bend strength) – describes a quality that is becoming increasingly important in the field of automation technology and many other industrial situations. The results that we have obtained from a series of experiments put us in a position to help you decide which alloy is most suited to your application, thereby possibly giving you a competitive advantage through the extended operational life of your products.

High-frequency (HF) technology in the cable industry

The term high-frequency is a fairly general one. Manufacturing electrical conductors for HF technology poses distinct challenges such as transmission loss, emission, crosstalk, wave impedance or skin effect, to name but a few. All of these and more will play a role in the main section below.

Miniaturisation

The label “miniaturised“ is attached to copper-based electrical conductors featuring a single-wire diameter of 0.05 mm or lower. They are mainly used in signal cables and data cables. Manufacturing miniaturised conductors poses a particular challenge.
