I believe that many people may not know what kind of material it is when they hear foam metal? In fact, the special feature of metal foam is that it is a metal material with a special structure, and there is a porous structure with a large number of foam pores on this metal material. This also makes the metal foam very lightweight during use; it also has good thermal and sound insulation properties, as well as shielding from electromagnetic signals.
1. Composition of porous structure
As a special metal material, metal foam has a structure very similar to that of sponge and is highly breathable. The porosity of the overall surface of the metal foam is more than 90%, and these pores have a diameter of millimeters. Although the metal foam itself has many pores, this does not greatly affect its strength and stiffness; on the contrary, the porous structure causes the metal material to collapse after encountering pressure, causing the pore structure to collapse, resulting in greater stress. force area, which makes this metal material have good shock absorption.
2. Metal foam is widely used
This metal foam has a very wide range of applications. As a special metal with high hardness and high rigidity, metal foam is widely used in aerospace, petrochemical, construction, transportation and other industries. Because of the good heat transfer properties of metal foam itself, it is very light and stiff, so you can almost see it on the landing gear and wing shells of spacecraft. Due to the looseness and porosity of metal foam, its sound absorption and sound insulation properties can also be used to make artificial bones, which also ensures that metal foam can be used as a noise reduction material; it has a very wide range of applications and application prospects.
3. Development prospects
Metal foam can be said to be a special metal material with good application prospects. Currently, in scientific research, metal foam is used in the military field. A military body armor that can block armor-piercing bullets is developed; at the same time, according to the characteristics of the foam metal itself, the foam metal is made into a lightweight stainless steel composite material for the protection upgrade of the armored vehicle, which also further reduces the weight of the armored vehicle itself.
