Aluminum is not strong, it is not a good conductor of heat. The strongest variety of Aluminum have around 75,000 psi tensile strength and when compared to steel of the same strength, aluminum is more expensive.

Advantages: 1. Aluminum does not rust like iron (steel). 2. Aluminum is much lighter than steel, making the car more fuel efficient.

Disadvantages: 1. More expensive. 2. More damage in accidents. 3.Probably harder to reshape after the accident (more expensive to fix after an accident.)

Is it best to make cars from Aluminum or Steel?

I would suggest that Aluminum is preferable. It is lighter than steel, which can result in a higher performance vehicle (faster acceleration, better braking, improved fuel economy). Furthermore, unlike steel, aluminum will not rust. Aluminum is also easier to recycle. Aluminum cars have a stiffer feel- giving them a sportier feel, and absorb impact about 1.5 times as well as steel, making them safer. The downside, of course, is the high cost of aluminum compared to steel.
