Automotive manufacturers emphasize automotive safety and lightweighting. This has driven the demand for innovative materials with superior energy absorption capabilities. Aluminum foam, with its unique properties, has become an ideal solution.
Aluminum foam is a lightweight aluminum alloy with a honeycomb structure. Its density typically ranges between 0.02 and 0.95 g/cm³, significantly lighter than traditional aluminum and steel.
Application of aluminum foam in automotive bodies
The low density of aluminum foam makes it ideal for automotive safety components. It is widely used in energy-absorbing bumper materials, crash beams, and door panels. High-end vehicles, including the Audi A8, have successfully adopted aluminum foam, enhancing vehicle safety and crashworthiness.
Performance advantages of aluminum foam
Tests by Tsinghua University have shown that aluminum foam's energy absorption capacity ranges between 2-25 J/cm³, with efficiency exceeding 0.8. Under equivalent weight conditions, its compressive strength is five times that of traditional steel and twice that of aluminum.
Experimental data shows aluminum foam has five times energy absorption capacity.

Additionally, the elastic modulus of aluminum foam ranges from 0.7-1.4 GPa, providing stiffness 50-100 times higher than traditional aluminum alloys. Its absorption efficiency increases by 20%-100% during high-speed impacts, further demonstrating its effectiveness in demanding safety scenarios.
Uses in electric vehicles and special-purpose vehicles
In electric vehicles, aluminum foam is integral for lightweight yet sturdy battery housings, reducing battery weight by 30%-60%, while providing excellent flame-retardant and explosion-proof characteristics. It is also widely used in armored and security vehicles to enhance protection.
