Abstract: Foam aluminum, as a new material with lightweight, porous structure, and multifunctional properties, has shown broad application prospects in the field of green buildings. This paper systematically reviews its preparation process advancements, including the optimization of foaming agents and parameter control in melt foaming, precise pore design in powder metallurgy, innovative preforms in infiltration casting, and emerging technologies such as 3D printing. It emphasizes achieving performance enhancement and environmental friendliness through green preparation and composite processes. Performance studies indicate that foam aluminum possesses excellent thermal insulation, soundproofing, and energy absorption characteristics, making it suitable for constructing efficient insulated walls, acoustic barriers, and seismic structures to replace traditional building materials. In innovative applications, its potential for artistic decoration and modular rapid assembly has promoted sustainable development in temporary buildings and post-disaster emergency scenarios. Economic and environmental analyses show that although initial costs are high, the energy-saving benefits and recyclability over the entire lifecycle reduce its carbon footprint compared to traditional materials. Combined with policy support and increased social acceptance, it offers significant competitive advantages. Future research needs to overcome production scale bottlenecks, develop intelligent responsive structures and interdisciplinary integration technologies, to promote foam aluminum as a core material for “carbon-neutral” buildings, contributing to urban ecological transformation and the construction of resource recycling systems.
