Metallic foams can be made of aluminum, steel, copper or nickel. They are the new generation porous functional materials with unique structure and properties. E.g. high specific surface area, small density, ultra lightweight, good thermal & sound insulation and able to absorb electromagnetic waves. These porous foam metals have been widely applied in aerospace, aviation, transportation, environmental protection, energy, biological and other high-tech or general industrial fields.
As a professional supplier, we can offer metallic foam materials of the following types:
Aluminum foam is made of pure aluminum or aluminum alloy by foaming process after adding additives. Thanks to its excellent physical, chemical, mechanical properties and recyclability. Aluminum foam is regarded as one of the most promising engineering materials, especially in the transportation, aerospace and building construction.
Steel foam (foam iron) and its alloy are made of nano- or micro-scale iron powder or iron alloy powder. The microstructure is in the form of open-cell three-dimensional structure with good mechanical and processing properties. Steel foam has micro-nano pore size, and the porosity ranges from 40% to 95%. Besides, the thickness of the material can be as thin as 0.1 mm.
Nickel foam is an excellent sound absorbing material, especially at high frequencies. The sound absorption performance in low frequency can be improved by designing the sound absorption structure. Nickel foam is also one of the best electrode materials for making cadmium-nickel batteries and hydrogen-nickel batteries.
The copper foam has good electrical conductivity and ductility. And its preparation cost is lower than that of nickel foam. Copper foams are ideally used as the material for production of battery negative electrode (carrier), catalyst carrier and electromagnetic shielding.
