Metal foam is a new type of material, although it has been widely used in batteries and other industries, the following briefly summarizes the basic characteristics of metal foam:
Due to the special structure of metal foam, it has many excellent properties that are different from traditional materials, such as:
1. High porosity: almost fully transparent structure with a porosity of more than 98%, as a filter material, the pressure drop is small and the flow rate is high;
2. Large specific surface area: In the case of the same porosity, compared with other porous materials, it has a large specific surface area;
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, the material is lighter in weight, and has high accommodating capacity. Good sound absorption, energy absorption and electromagnetic shielding performance;
4. Possess metal properties: Foam metal can be made of nickel, copper, iron, or alloy materials, different substrates have different metal properties, such as fire resistance, non-toxic, no falling residue, recyclable, thermal conductivity, etc., suitable for wide range;
5. It can be welded, cut, thinned, rolled and other mechanical processing, and metal materials can be recycled, which is beneficial to environmental protection and saves costs.
