5 metals used to make cars

Steel

Let’s start with the obvious one. Steel is everywhere in a car: chassis, body panels, structural elements. You name it, steel is there! It’s strong, relatively affordable, and does a great job of keeping you safe in a crash. No surprise it’s still the go-to for most manufacturers.

Aluminium

The lighter, more efficient option. As it’s lighter than steel, fuel efficiency and performance are top notch. You’ll often find it in bonnets, doors, and even full car bodies in some modern models.

Copper

You won’t always see it, but it’s there. It’s used in wiring, electronics, and increasingly in electric vehicles. Without it, your car’s tech simply wouldn’t function.

Magnesium

You use it for sleep, car manufacturers use it for shaving weight off.

Zinc

Zinc plays a key role in protecting cars from rust and it’s a level of protection that lasts. It’s often used as a coating on steel parts to stop corrosion, especially in areas exposed to the elements. Processes like zinc nickel plating take that protection a step further, helping components last longer under tough conditions.

If you’re interested in how that works in more detail, sites such as www.swmf.co.uk/surface-coatings/zinc-nickel-alloy-plating/ provide further detail.

A little insight

Cars are evolving fast, especially with the push towards lighter and more efficient designs. According to a BBC report on the future of electric vehicles, material choices are becoming more important than ever as manufacturers balance weight, safety, and sustainability.

So, while steel might still dominate, it’s really a mix of metals that create your car.
