Metal foams are a category of advanced materials with properties which make them promising for a number of applications. In the case of aluminum foams, these include:

low density, good strength, impact resistance, noise absorption and sound proofing, fire-resistance, vibration damping, electromagnetic shielding, humidity and corrosion resistance, and environmental friendliness. 

Above features have attracted the attention of many engineering designers around the globe so that this family of materials is now in use in numerous fields such as: transportation, construction, smart cities, decorative as well as many other applications.
