Aluminum can be used to increase the size and energy absorption capacity of a vehicle’s front and back crumple zones, enhancing safety without increasing weight. Vehicles made from lighter aluminum require shorter stopping distances, helping to prevent collisions.
Why do cars use aluminium?
The U.S. Aluminum Association states that, pound for pound, the light metal absorbs twice the crash energy of steel and performs as well in an accident. This is a significant benefit. A lighter vehicle also provides advantages in stopping distance, handling and performance.
Where on a motor vehicle would aluminum alloys be used?
Aluminium alloys are widely used in automotive engines, particularly in cylinder blocks and crankcases due to the weight savings that are possible. Since aluminium alloys are susceptible to warping at elevated temperatures, the cooling system of such engines is critical.
What aluminum alloy is used for cars?
The common aluminum alloy used in cars are mainly divided into 5xxx and 6xxx aluminum alloy for the car body and chassis: 1. After stamping, 5182 aluminum sheet has no cracks, and it is often used in car doors, car hoods, and car front and rear fenders.
Why are metal alloys used on cars?
Every pound of aluminum used in an automobile, in lieu of steel, reduces the overall vehicular weight by a pound. This metal allows for safer and more efficient vehicles to enter the roadways. Over the years, aluminum has continued to increase in its popularity within the automotive manufacturing industry.
Is aluminum and aluminum alloys are the best material for car manufacturing?
According to the Aluminum Association, aluminum has favorable properties for automobile manufacturing, and is now second only to steel as the most used material in vehicles.
How is aluminum used in transportation?
Originally indispensable for its lightweight for the aerospace industry, aluminium is now widely used in cars, buses, coaches, lorries, trains, ships, ferries, aircraft and bicycles. The aluminium industry supports the need to develop cleaner and more sustainable means of transportation.
Why is aluminium used for chassis?
High performance Aluminum alloys for chassis applications
Aluminum is extensively used for automotive chassis and engine applications. Properties like useful strength, low density, high thermal conductivity, excellent machining behavior and good corrosion resistance are the main reasons for using Aluminum.
