In addition, life cycle analyses suggest that the use of recycled metals for vehicle construction is associated with fewer emissions than those needed for production from raw materials. Ultimately, this helps ensure higher quality products with minimal environmental impact.
Design Complexity
The use of magnesium in automotive lightweighting has the potential to greatly reduce fuel consumption and emissions, increase performance, and reduce overall vehicle costs. As a result, it is essential that durability testing and thermal management be considered when designing a vehicle with magnesium components.
Durability testing is crucial for ensuring that the components are able to withstand the rigors of daily driving for extended periods of time. The tests should include both static and dynamic tests to ensure that the materials will hold up to both normal everyday driving conditions as well as more extreme conditions such as off-roading.
Thermal management must also be taken into account when considering a magnesium-based design due to its relatively low melting point. Special attention should be paid to areas such as engine compartments where temperatures can exceed those at which magnesium melts, leading to component failure. Furthermore, insulation may need to be used in order to keep temperatures low enough so that the components do not become damaged or fail prematurely.
By taking into account durability testing and thermal management requirements when designing a vehicle with magnesium components, automakers can ensure that their vehicles are safe and reliable while still benefiting from the weight savings offered by using this material.
