Metal foam, also known as porous metal, is a material composed of solid metal with a large number of interconnected pores. These pores not only give metal Foam its characteristic lightweight and porous structure, but also its unique properties, such as a high strength-to-weight ratio, excellent impact resistance, and superior energy absorption capabilities. These properties make metallic foams an attractive material for a variety of applications, including the aerospace, automotive, military and biomedical industries.
So why is foam metal so expensive? Several factors contribute to the high cost of this material. First of all, the production process of foam metal is complex and the technical requirements are advanced. The most common method of producing metal foam is to use metal powder and a foaming agent, mix them together, and then heat them to create bubbles in the metal matrix. The process requires precise control of temperature, pressure and chemical composition, which increases production costs.
Additionally, the materials used to produce metal foams are often expensive. High-quality metal powders and foaming agents are essential to create metal foams with the required properties, and these materials are expensive. In addition, the production of metal foam often involves multiple steps such as powder metallurgy, foaming and sintering, all of which require specialized equipment and skilled labor, further increasing overall costs.
