Features metal foam

Metal foam is a new material , although already in the military and the battery industry has been widely used , but is widely used in other industries has just started, it is not enough on its deep understanding , following a brief summary about the basic features of metal foam :

Because of the special structure of metal foam , it has many excellent properties different from traditional materials , such as :

1 the through hole of the high : through hole ratio of 98% or almost entirely transparent structures as a filter material , the pressure drop is small, a high flow rate ;

(2) specific surface area : the through hole at the same rate , the porous material and the other has the largest surface area in comparison ;

3 porosity, pore structure uniformity : more than 95% porosity , permeability porous three-dimensional structure , and has a good metal strength , the same size, lighter weight materials , but is also able to accommodate a maximum , and there good sound absorption , energy absorption , electromagnetic shielding performance ;

4 has metallic properties : metal foam may be made from nickel , copper, iron , or an alloy material , the type of metal substrate having different properties, such as fire , non-toxic , non- residue falling , recyclable , thermal conductivity , etc., for a wide range ;

5 can be welded , cut, pressed thin, rolls and other mechanical processing , and metal materials can be recycled , environmentally friendly while saving costs.
