A lot of things are made to move around. And whether you will push it, carry it, drive it or fly it, you most likely want it to be lightweight. In fact, you probably want it to be made in aluminium.
The density of aluminium, and thus weight, is a third of the density of steel and copper. That is why car producers, committed to reducing greenhouse gas emissions, is using more and more aluminium in cars.
Lighter cars consume less fuel, and less fuel means less emissions.
And here is today’s fun fact: For every kilo aluminium added to a car, the total weight of the car is reduced by more than 1 kilo!
15 years ago a European car contained about 120 kilo aluminium.
As more and more engine parts, tubes, body parts, doors and closures are made of aluminium instead of steel or copper, the aluminium intensity is close to 200 kilo today, and in the next ten years it may reach 280 kilo.
The light-weighting revolution in cars is about to make the automotive industry the most important global market for aluminum, and the motivation is to comply with legislation aiming to combat climate change.
No wonder we like to think that industry and environment can go hand in hand, being in the business of making the world lighter.
