Aluminum extrusions are highly valued for their unparalleled benefits in strength, while also remaining incredibly light in comparison to materials like steel. It should be no surprise, then, that a large variety of industries make use of aluminum’s benefits, and the automotive industry is no exception. Here’s how the auto industry uses aluminum extrusions to benefit and improve modern cars.

Weight and Fuel Efficiency

The first and foremost benefit of aluminum extrusions in the auto industry is how they allow cars to be much lighter without compromising the strength and durability of the car’s construction. The lighter the car, the more fuel-efficient it becomes, since the engine doesn’t have to work as hard to propel the car forward. This allows cars to have greater gas mileage and save the car’s owner a lot of money in the long run when they don’t have to refuel as often. As a side benefit, this allows cars to be more environmentally friendly as less fuel is burned, and the aluminum in the car’s chassis can be recycled and reused for other applications.

Malleability and Versatility

While fuel efficiency is one of the more tangible benefits of how the auto industry uses aluminum extrusions, an equally important advantage is how easily aluminum extrusions can be formed for any purpose. Aluminum is very malleable and versatile, capable of taking on many shapes and forms in order to fit any application, thanks to custom aluminum fabrication. This is harder to do with other materials that are more difficult to cut or bend, and that’s why older cars are often bulkier and heavier.

Constructing Vehicles

Aluminum extrusions in cars first saw widespread adoption in the 1990s, but at the time would only be used for bumpers and door beams. Since then, aluminum extrusions have become more favored and innovated upon, and you can find aluminum extrusions being used to construct a majority of a car’s chassis. To name a few examples, this includes:

• Roof rails

• Front and rear headers

• Roof support pillars

• Electronics housing

• Driveshafts

• Roof racks

Aluminum extrusions are one of the greatest innovations within the auto industry and have singlehandedly improved the designs of our cars. However, this is just one of the many industries aluminum extrusions benefits, and you can find aluminum extrusions almost anywhere.
