When it comes to automotive, vehicle size, not weight is the leading safety factor.
Aluminium is used to maintain or even increase the size and energy absorption capacity of the critical areas of the vehicle. Its unique strength versus weight ratio, allows for max energy absorption in front and back areas of a vehicle, thereby improving safety without increasing the weight in total.
The lowest the weight of a car or a vehicle, the less fuel or battery power is needed to move it.
The lowest the weight, the highest the distance range this can move with a single fill whether gasoline, petrol or battery pack.
As more hybrid and electric vehicles hit the roads, the need for heavy battery packs can be reduced in an aluminium intensive vehicle as less overall weight requires less power.
Less power, means fuel costs savings, better efficiency and less gas emissions
Aluminum Safety Advantages
- Aluminum can be used to maintain or even increase the size and energy absorption capacity of a vehicle’s critical areas for higher safety without increasing weight.
- Aluminum can absorb twice as much crash energy as steel.
- Aluminum components can be designed to fold predictably during a crash test, allowing the vehicle to absorb much of the crash energy.
- Aluminum allows vehicles to be lighter and as such to require shorter stopping distances to avoid crashes.
Aluminum´s Safety Advantages
- 5% – 7% fuel savings can be realized for every 10% weight reduction when traditional steel is replaced with aluminum.
- Weight reduction due to the higher use of aluminum frames and parts allow the use of smaller and more efficient engines.
- Using aluminum in electric vehicles has a clear effect on the driving range as more can be travelled with less weight.
