The Top 5 Materials Used in Auto Manufacturing

Car Anatomy

Ever wondered what sort of materials your car is made of? It’s probably never crossed your mind before, but we here at Roberts AIMPC believe that it’s important for motorists to know the materials used in auto manufacturing. We hear a lot about the different parts that make up our vehicles, like the transmission, engine, exhaust system, but nothing about the actual raw materials.

Here’s a list of the five most popular materials in the auto manufacturing industry.


Did you know that the average sedan contains around 2,400 pounds of steel? And that’s not all. Most SUVs these days contain as much as 4,000 pounds of this heavy metal. Steel is used to form not just the main skeleton of the vehicle, but it’s also used in other parts such as the body panels and the steel tubes. And since steel manufacturing has greatly evolved over the years, car manufacturers have a wide array of different types of steel to choose from. That means more innovations that will ensure your safety on the road.


Although aluminium is said to be a new material in the world of auto manufacturing, it’s becoming increasingly popular because of its tough yet lightweight nature. Aluminium is used to create the body panels of the lighter and more performance-oriented modern models like the Acura NSX and the Audi R8. Over the past years, we’ve seen automakers switch from the traditional iron blocks to aluminium construction for engines. It may not be as durable, but it guarantees a big boost when it comes to overall performance.


This is a favourite raw material in the auto industry primarily for its durability and flexibility. Today’s modern cars use a tremendous amount of plastics, making up almost 50 percent of total construction. From your dashboard, to the gauges, dials and switches, and even seat belts and airbags, all these are made from some form of modern plastic. It’s also used in some parts of the body structure for its lightweight nature.


Apart from fuel, what does your vehicle need in order to run? Tires, of course! And this is why rubber deserves to be on our list of top 5 materials in auto manufacturing. Many people may take their cars’ tires for granted, but without it, the auto manufacturing industry will be in a standstill – literally. The rubber part of the tire is what protects the wheel and its internal parts from constant friction, making fuel mileage and road safety possible.


Lastly, let’s not forget glass. Can you imagine your car without glass? Because we ourselves sure can’t. Glass is one of the unsung heroes of auto manufacturing.  Without it, it would be either impossible or unsafe for us to see our surroundings as we operate our vehicle. Although its primary use can be found in windshields, you can also see traces of glass in the rear and side view mirrors. You’ll also find that’s it heavily used in the navigation screens for the more recent car models.
