Benefits to a Lighter, Aluminum Car Body

The automakers are looking for alternatives to produce lighter vehicles that help increase fuel efficiency, by replacing steel with aluminum, which is between 45% and up to 60% lighter. Car manufacturers estimate that an average vehicle will lose 181.4 kilos by 2025 by doubling the use of aluminum. Currently a car can weigh between one and two tons (1,000 to 2,000 kilos), depending on the format.

What are the benefits of lighter car body?

The use of steel, which now represents 56% of the average weight of a vehicle, is expected to decrease to 46% of the total weight. Aluminum is 45% lighter than steel and although it is twice as expensive. Car manufacturers now produce aluminum auto parts, engine heads, mono-blocks, transmission housings and SAF Aluminum structural parts which are 60% lighter than their comparable parts made of iron or steel. Weight reduction in cars is driven by the regulations of the automotive industry that seek to reduce emissions and make fuel efficiency or fuel efficiency more efficient. For every 100 kilograms less in the vehicle, 9 grams of CO 2 per kilometer can be reduced and gasoline consumption is reduced by 0.3 liters per 100 km.

Benefits of using Aluminum in Parts:

Expert manufacturers focus on weight reduction in two segments – in the powertrain components division where mono-blocks, engine heads and transmission components are located, and in the structural components segment for luxury cars. Currently, they works in two structural component programs and intends to invest to expand its manufacturing capacity.

The tendency to reduce weight continues beyond the powertrain and today they are concentrating efforts to replace the metal structure of the vehicle with aluminum, which will represent a very important market. By 2020, aluminum engine blocks are expected to represent 69% of global production of these components against 59% today.

Cost effective for consumer:

The cost of replacing steel with aluminum is one dollar per kilo less weight, but that consumers can recover in 2 years thanks to the fuel savings of a more efficient vehicle. The use of aluminum also requires greater investment in the production lines as it is more difficult to weld. Corrosion resistance, lightness and lower consumption are some of the advantages that this material provides.Thus, weighing less, fuel consumption (and consequently polluting emissions) would also be lower. Its high strength aluminum body that does not rust, is lighter and more resistant to bumps or dents. This cutting-edge technology in the use of new materials allows a more agile handling.

What are these brands looking for using Aluminum?

All of them agree that they want to reduce fuel consumption for customer satisfaction and favor environmental care. For this, Alusion provides the vehicle with lightness, strength and durability, in addition to being a 100% recyclable material. Customer satisfaction and environmental conservation are basic objectives. For this reason, it offers its customers the profiles of Aluminum with Thermal Break Bridge that allows its window to have excellent thermal performance, be very resistant and be durable.
