Why metal foam provides cushioning protection?

Principle of making Metal foam
Metal foam is a material with a microporous structure made by mixing metal powders, blowing agents, and other additives and sintering them at high temperatures. During the sintering process, the blowing agent produces bubbles, which causes the material to form tiny pores, thus forming a foamy metal material.

Characteristics of metal foam
1. Lightweight: Since the volume of metal foam consists mainly of micropores, its density is low and it is very lightweight.
2. High strength: the microcellular structure of the metal foam increases its strength, making it highly resistant to compression.
3. Good energy-absorbing performance: Since the pores of metal foam can absorb impact energy, it can play a good role in cushioNing protection.

The application of metal foam in the field of cushion protection
Metal has a wide range of applications in the field of cushioning protection due to the foam's lightweight, high strength, good energy absorption performance, and other characteristics. For example, in the field of transportation, foam metal can be used for automobiles, trains, and other means of transportation buffer devices, which play a role in protecting passengers and vehicles. In the field of electronic products, metal foam can be used in cell phones, tablet PCs, and other electronic products cushioning protection, to prevent the equipment from accidental fall damage. In the field of sporting goods, foam metal can be used in helmets, protective gear, and other protective equipment, to play the role of cushioning protection.

In summary, metal foam can play an important role in the field of cushioning protection due to its lightweight, high strength, good energy absorption performance, and other characteristics.
