Aluminium used in transport reduces the weight, fuel consumption and greenhouse gas emissions.

Posted by: Alloy 2021-01-08 Comments Off on Aluminium used in transport reduces the weight, fuel consumption and greenhouse gas emissions.

As well as direct weight reduction by material substitution, there are additional possibilities for component light-weighting. Aluminium-specific fabrication techniques, such as complex, multi-hollow extrusions or thin-walled, high-strength, vacuum die castings, enable new design solutions.

When Audi designed the A8 model, they had to choose between a steel body-in-white with a mass of 441 kg and an aluminium alternative of 247 kg. Once Audi decided in favour of the aluminium alternative, they could also realise additional weight-saving measures, e. g. a smaller engine or a smaller fuel tank would fulfil the given requirements for the car (acceleration, mileage per tank filling). Audi reported such “indirect” weight savings as 45 kg which is 23% of the direct weight savings of 194 kg. This means that the 247 kg aluminium body-in-white effectively reduces the car weight by 239 kg.  Other vehicle studies suggest a secondary weight saving range of 50 – 100%.

Guest contributors are welcome at the Alloy Wiki.It is a weekly wiki and guide on alloy information and processing technology, while also about the vast array of opportunities that are present in manufacturing. Our team of writers consists of a Machining Material Supplier / Machinist / Tool and Die Maker, a Biomedical Engineer / Product Development Engineer, a Job Development Coordinator / Adjunct Professor, and a President and CEO of a manufacturing facility. The Jaguar XE brings new levels of aluminium-intensive lightweight construction and is projected to deliver fuel economy of over 75 mpg* (less than 4 litres/100 km) on EU combined cycle (*subject to certification). The XE uses aluminium-intensive monocoque which accounts for 75% of the vehicle’s structure. The reduction in weight ensures that the XE is the most fuel-efficient Jaguar yet with fuel consumption and CO2 emissions on the NEDC combined cycle of over 75 mpg and less than 100 g/km respectively. The Jaguar XE is also the first car in the world to make use of a new grade of high strength aluminium called RC 5754 which has been developed specifically for the XE. This new alloy features a high level of recycled material and makes a significant contribution to Jaguar’s goal of using 75% recycled material by 2020.
