  • Metallic melts can be foamed in one of three ways: by injecting gas into the liquid metal from an external source, by causing an in-situ gas formation in the liquid by admixing gas-releasing blowing agents to the molten metal, or by causing the precipitation of gas which was previously dissolved in the liquid
  • Aluminium foam originates by solidification of liquid aluminium in which fine gas bubbles are dispersed. Aluminium foam possesses high stiffness at very low density. It absorbs high impact energies regardless of the impact direction. It is highly efficient in sound absorption, electromagnetic shielding and vibration damping.
  • Aluminium foam is a highly porous cellular material were pores represent 65 - 90 % of the total volume. The foaming process principally does not affect the properties of the cell-wall material.
  • The production process begins with the mixing of metal powders - elementary metals, alloys or powder blends - with a foaming agent, after which the mix is compacted to yield a dense, semi-finished product.This mixture may be compacted by various powder consolidation processes such as extrusion, hot pressing, or hot isostatic pressing, to produce a semi-product having a gas tight metallic matrix.
  • Foaming a piece of precursor material in a furnace results in a lump of metal foam with an undefined shape unless the expansion is limited in certain directions. This is done by inserting the precursor material into a hollow mould and expanding it by heating.
  • Lost foam cast aluminium A356 is increasingly used in the automative industry for engine block and cylinder head applications due to its combined properties of excellent castability, corrosion resistance and in particular, high tensile and fatigue strength after heat treatment.
  • Solid metallic foams exhibit many unusual combinations of physical and mechanical properties that make them attractive in a number of engineering applications. For instance, when used as cores of structural sandwich panels, they offer high stiffness in conjunction with low weight. Their use in energy absorption devices exploits their capacity to undergo large deformations at almost constant stress.
  • Metal foams, full of tiny air bubbles like a sponge cake, are gradually making inroads in industrial applications. Lightness and high energy absorption are two demanded material characteristics. Less known is the use of open-pored variants for decorative purposes.
  • The closely related closed-pore metal foams are already making headway in numerous applications. Their low weight predestines them for use in light but rigid assemblies in machines with moving parts.
  • Metal foams made of grains and pores only nanometers or billionths of a meter wide are lighter than Styrofoam, enough to float on water. The extraordinarily high surface areas these unprecedented foams possess suggest they could serve as excellent platforms for chemical reactions that for instance help generate electricity or remove pollutants, experts told UPI's Nano World.
