Application prospect of foam metal

Foamed metal has been widely used in a series of industrial development such as aerospace, petrochemical, environmental protection, construction and traffic protection. According to the problems it is aimed at, we divide its application direction into four directions:

Sandwich: Because metal foam has certain strength, ductility, low density and low weight, it is often used to make multiple laminated composite materials. Applications. For example, sandwich materials for aircraft, mobile buildings, spaceships, sleds, etc.

Support form: foam is light, hard, bearing capacity, heat transfer performance is good, widely used in wing shell, missile nose stack, spacecraft landing gear and other fields. In addition, it is also necessary to use foam metal for components or railings in buildings that require light, hard, and fire-resistant properties, as well as for the reinforcement of some thin-walled cylindrical shells.

Cushioning: Metal foam has the ability to absorb energy and reduce the external force to a safe range. Its strength is controlled by adjusting the density of the foam metal, which can be adapted to cushioning applications of a variety of materials. Under constant stress, metal foam can withstand large compressive strains and absorb a large amount of energy. As far as the manufacture of artificial bones is concerned, metal foams have high mechanical properties and can also meet the large pore size required by human bones.

Noise reduction: Foam metal has good sound absorption and sound insulation effects, and is suitable for highways, automobile internal combustion engine cylinders, high-speed train power generation rooms, radio recording, etc.

The development and utilization of new energy has been a hot topic in the scientific community in recent years, and clean and renewable energy has become a hot topic. Hydrogen is an environmentally friendly energy source. In addition to electricity, scientific research activities around the preparation and storage of hydrogen are also very active. And hydrogen production is also a major application of foam metal. It can be said that the application of foam metal has a wide range of prospects, involving almost all planned future industries, including batteries, new energy vehicles, aerospace and so on.
