Aluminium a strong fit for automotive subframes

Subframes made with aluminium have the strength and stiffness that the application requires.

More than a million cars are driving around with rear and front subframes that use either rolled aluminium or extruded aluminium produced by Hydro. Or both. Because aluminium suits the application.

A subframe is a structural component that carries specific automotive components, such as the engine, and spreads the weight over a wider area of the body structure. They tend to be axle-type structures or perimeter frames, joined to the vehicle either with bolts or through welding.

Most light vehicles today utilize both front and rear subframes. They need to be stable to ensure excellent road contact, and light, to guarantee passenger comfort in all types of road and driving conditions.

The key is identifying the right material for the application.

Aluminium the right material

Subframes made with aluminium have the strength and stiffness that is required. These also help reduce the weight of the vehicle, benefiting consumers, and can help lower production and assembly costs, benefiting carmakers.

Interestingly, aluminium subframes can be found in various product forms: sheet, extrusions and castings. The common denominator is the light metal.

A cost-efficient solution for subframes

Whether in sheet or extruded solutions, subframes manufactured with the right aluminium alloy can withstand the complex temperature loadings found near heat sources like the engine, exhaust system or brakes. Strength, stiffness and corrosion resistance are also part of the package.

And aluminium is fully recyclable.

The fewer parts used in an aluminium frame, the stronger the frame.

The Norwegian company Alustar bases its offshore scaffolding concept on aluminium, because it weighs half as much as a steel-made concept and is just as strong. This makes it easier on installers.

True! When you construct and fit them properly, aluminium assemblies for offshore structures will not corrode.
