Foam metal is a new type of material. Although it has been widely used in the military and battery industries, its wide application in other industries has just started, and people still don’t have a deep understanding of it. Here is a brief summary of the basic characteristics of foam metal:

Due to the special structure of foam metal, it has many excellent properties that are different from traditional materials, such as:

1.  High through porosity: almost fully permeable structure with a through porosity of more than 98%. As a filter material, it has small pressure drop and high flow rate;
2.  Large specific surface area: under the same through-hole rate, it has the largest specific surface area compared with other porous materials;
3.   High porosity and uniform pore structure: the porosity reaches more than 95%, which is a three-dimensional porous and transparent structure, and has good metal strength, the same volume, lighter material weight, the highest accommodation, and good sound absorption, energy absorption and electromagnetic shielding properties;
4.   metal properties: foam metal can be made of nickel, copper, iron or alloy materials. Different substrates have different metal properties, such as fire protection, non-toxic, no drop residues, recyclable, heat conduction, etc., and have wide application scope.
5.  It can be welded, sheared, thinned, rolled and other mechanical processing. At the same time, metal materials can be recycled, which is conducive to environmental protection and cost saving.
