Replacing copper in automotive battery cables
LEONI Kabel is replacing copper with aluminium in its automotive battery cables to save money and reduce weight. There is no difference in performance.
Passenger vehicles have more cabling than you might imagine. Your car probably has about 25 kg in total. Copper is the material traditionally used in the cables.
Extruded solid aluminium rod
The wiring systems and cable technology leader LEONI has partnered with Sapa to come up with an aluminium solution that replaces copper in its automotive battery cables. The cable is an extruded solid aluminium rod that is HYCOT®-coated with either PA, PE or XPE coatings.
One-third the weight, same performance
It is one-third the weight of the copper cables and costs less. Their performance is the same.
LEONI is not the only large customer to substitute materials in its battery cables. Jaguar is also using aluminium instead of the heavier copper alternative.
These are individual, case-by-case processes with weight and cost savings as the incentives. And they are very successful cases, as well.
