Aluminium is strong, but only 30% of the weight of steel, so means lighter cars with lower fuel consumption and less emissions. Components and systems include aluminium car roof panels, body applications, roof rails, finished trim, structural parts, radiators, structural components, tubing for heat exchangers, extrusions and engines. Aluminium is also increasingly used to make railway carriages.
Light vehicles need a body structure that is rigid to support weight and stress and to securely tie together all the components. Aluminium is well-suited for structural parts such as frames and sub-frames, impact beams and bumpers.
The growing trend for light weighting is aided by adding less grain refiner, reducing the number of inclusion related defects and allowing thinner aluminium sections to be produced without affecting grain size or other properties.
We have Optifine grain refiners that are particularly suited to the automotive industry with its challenging requirements for aluminium alloys that provide incredibly high tensile strength such as extrusion-based crash management systems, body-in-white structural components and battery enclosures.
