The auto industry uses aluminum for the vehicle frame and body, electrical wiring, wheels, lamps, paint, transmission, air conditioner condenser and pipes, engine parts (pistons, radiator, cylinder head) and magnets (for speedometers, tachometers and air bags).
Are car bodies made of aluminum?
The third material that can be used in car bodies is aluminum. … Aluminum allows cars to be lighter, so they get better gas mileage and what’s even better is that it doesn’t rust. As a result, aluminum-based frames are more expensive than steel frames, so they are typically used for high-end vehicles.
What is aluminum used for in a car?
Because aluminum is lighter, it allows automakers to increase dent resistance—they can make body panels thicker while still lowering weight. And a lower weight vehicle has better acceleration, better braking and better handling.
How much of a car is made of aluminum?
* Cars have been increasing in weight since the 1970s when the average vehicle weighed about 800 kg. The average weight is now around 1300 kg, with aluminium accounting for around 10 percent.
Are car frames steel or aluminum?

Why is aluminum worth more than gold?
While aluminium is the third most abundant element and most abundant metal in the Earth’s crust, it was at first found to be exceedingly difficult to extract the metal from its various non-metallic ores. The great expense of refining the metal made the small available quantity of pure aluminium more valuable than gold.
Are BMW made of aluminum?
Looking to reduce weight and increase fuel efficiency, automakers around the world, including BMW, have begun using aluminum in the structure of their cars. Aluminum fits the bill as it is lighter than steel and sustainable because it can be recycled.
