- Aluminum foam
originates by solidification of liquid aluminum in which fine gas
bubbles are dispersed. Aluminum 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.
- Aluminum 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
aluminum A356 is increasingly used in the automotive industry for
engine block and cylinder head applications due to its combined
properties of excellent cast ability, 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.
