Aluminium foams are the frontiers of new light weight materials. They are created by gas injection foaming, that is by injecting gas bubbles into the metal melt through an orifice. We developed an original metal foaming technology which resulted in a new type of metal foam called ALUHAB, which can be produced with controlled bubble size and mechanical properties. It is manufactured from a special foamable aluminium alloy containing ultrafine particles (80-3000 nm sized). The technique relies on a direct gas injection with a loud-nozzle, and the bubbles are regulated by the frequency and power of the sound (so called acoustic radiation pressure). The size of the bubbles is depending on the applied sound pressure. The oscillation induced external force (acoustic radiation force) modifies bubble formation mechanism and helps bubble detachment in its early stage. This extra force can significantly decrease the bubble size into the sub-millimetre range and it can be kept uniform. This technology provides extremely stable re-meltable metal foams, which can be casted into complex shape while the material properties do not change. The ALUHAB once made can be transported and re-melt at the place of the use (for example at a foundry).
