in relation to copper prices. It wasn't just a case of cost, there wasn't enough supply and I believe there was a prioritisation of its use for wiring etc.
During this time vehicle radiators which had traditionally been made in copper and brass switched to aluminium. Volkswagen when switching from air cooled cars had to recognise the difficulties of copper shortages and the impact that would have on supplies so decided to make the radiators from aluminium, besides a cost advantage over copper it gave them greater assurance over future raw material supplies.
