The special three-dimensional three-dimensional structure of foam metal makes it have many excellent properties that are different from traditional materials, such as:

1. high porosity: the porosity can reach more than 98% of the almost fully permeable structure, as a filter material, small pressure drop, high flow rate, excellent permeability.
2. large specific surface area: with the same porosity, it has the largest specific surface area compared with other porous materials, up to one square meter per gram or more.
3. high porosity and uniform pore structure: the porosity is more than 95%, three-dimensional porous and permeable structure, and has good metal strength, the same volume, the material is lighter in weight, and also has the highest capacity, and has good sound absorption, energy absorption, electromagnetic shielding properties.
4. has metal properties: foam metal can be made of nickel, copper, iron, or alloy materials, different substrates have different metal properties, such as fireproof, non-toxic, no falling residue, recyclable, thermal conductivity, etc., a wide range of applications.
5. can be welded, sheared, pressed thin, rolled and other mechanical processing, while the metal material can be recycled, which is conducive to environmental protection and cost savings at the same time.
