What is Aluminium foam, and how strong is Aluminium foam?

Aluminum foam is a material made of Aluminium, which is also populated with a large volume of pores or cavities. It is a solid material filled with pores such that up to 95% of the volume consists of gas-filled voids in two different structures.

Like other metal foams, Aluminium foam is extremely durable and lightweight, with a large surface area to volume ratio. In addition, the non-flammable material inherits all of the excellent properties of its parent metal, Aluminium, such as recyclability, heat and corrosion resistance, strength, electrical and thermal conductivity, etc., but at a fraction of the weight.


How strong is Aluminium foam?


Aluminum Foam is extremely strong and can absorb a great deal of mechanical energy when deformed, making it an attractive material for impact energy absorbers. In addition, unlike polymeric foams, which tend to spring back, Aluminium foams do not do this, preventing any secondary damage.

An especially strong format of Aluminium foam is Aluminium foam sandwich (AFS) panels, where two metallic dense face sheets enclose within them a core made of metal foam, of Aluminium or Aluminium alloy.


How is Aluminium foam made?


Open-cell and closed-cell foams can create in one of two ways. The first method injects gas into metallic melts, and as gas bubbles through the molten metal, a foam is created, which is then removed and allowed to cool.


What is Aluminium foam used for?


Closed-cell Aluminium foam is widely used as a lightweight construction material in its original format and as sandwich panels, which are valued for their low density and very high stiffness.


Is Aluminium foam expensive?


Metal foams, as a whole, are less inexpensive than sheet metals or other polymeric counterparts. It is because of the number of processing steps and specific raw materials needed to facilitate their manufacture. In addition, they are expensive due to complicated and energy-intensive manufacturing procedures. To buy aluminum foam substrates, get reliable foam substrate suppliers online.
