Abstract:

Open-cell metallic foams or porous metals have a distinctive combination of excellent structural performance and superior functional characteristics, such as their light weight, energy absorption, sound absorption, heat dissipation, and electromagnetic shielding. As a primary representative of metallic foams, aluminum foam has developed into a new engineering material with many unique applications in the fields of aerospace, automotive industry, petrochemical industry, building materials, and etc. This paper summarizes the fabrication methods, properties, and applications of open-cell aluminum foams. The current status and development trends are also introduced.

Key words: Open-cell aluminum foam, Fabrication method, Property, Application
