The new aluminum foam material is a new type of lightweight functional-structural integrated material composed of aluminum or aluminum alloy matrix and pores. The special structure of the new aluminum foam material determines its lightness, high porosity, High specific surface area and other characteristics, thus obtaining excellent characteristics that many dense metals do not have, such as strong energy absorption, impact resistance, high specific strength, electromagnetic shielding, sound absorption performance, high damping, low thermal conductivity, Low conductivity, etc. The performance of the new aluminum foam material mainly depends on the pore structure parameters such as porosity, pore diameter, through porosity, pore structure type, specific surface area and the metal matrix.

Compared with dense metal materials, new aluminum foam materials can be used as functional materials as well as structural materials. Usually, new aluminum foam materials have dual functions of function and structure, and are durable and easy to recycle. It has huge application prospects in the fields of industry, military, aerospace and construction.
The application of new foamed aluminum material as a structural material, due to the existence of a large number of pores in the foamed aluminum, it has the characteristics of light weight and high specific strength, making it an ideal filling material for lightweight composite sandwich panels or sandwich tubes. The new foamed aluminum material is used as the filler of the sandwich composite board, which is not only light in weight, but also has high strength and stiffness. The compressive strength, stiffness and energy absorption properties have been greatly improved. Compared with the traditional honeycomb sandwich material, the new foamed aluminum material has higher performance and better formability, and overcomes the disadvantage of the anisotropy of the honeycomb sandwich material. Using a new foam aluminum material to replace the expensive honeycomb interlayer material can greatly reduce the cost while obtaining higher performance. In the construction industry, new foamed aluminum materials or other foamed metals can be made into light, hard, and fire-resistant components, railings or supports, such as high-frequency and high-speed acceleration and deceleration of modern elevators. quality foam metal material to reduce energy consumption.
