INTRODUCTION


Metal foam is a dispersion of gas bubbles in a metallic bulk material
These are extremely lightweight materials
It contains 50% or more holes
They have some very promising properties

Structure o f metal foam
In metal foams cells are divided into distinct cells. the boundaries of these materials are made of solid material, the interior are voids.

METAL FOAM
BY cloud2511

Metal foam is a cellular structure consisting of a solid metal, frequently aluminium, containing a large volume fraction of gas-filled pores. The pores can be sealed (closed-cell foam), or they can form an interconnected network (open-cell foam). The defining characteristic of metal foams is a very high porosity: typically 75-95% of the volume consists of void spaces. The strength of foamed metal possesses a power law relationship to its density; i.e., a 20% dense material is more than twice as strong as a 10% dense ....etc
