Metal foam is a hollow metal material composed of a special structural metal network, thus it has strong toughness, lightweight, high surface hardness, low noise, good heat insulation, and other excellent properties. At present, the application of metal foam is getting wider and wider, widely used in a variety of fields, with broad potential and a promising future.

In the 21st century, with increasingly advanced military equipment, both offense and defense must rely on scientific, powerful and lightweight body armor systems (helmets, undershirts, shoulders, face masks) to stop themselves from being turned into cannon fodder.
What body armor is safer now that military technology has advanced? The latest breakthrough is bulletproof undershirts made with composite metal foam that can disintegrate a happy-flying bullet.
It's not just any metal, but made by melting aluminum around a hollow metal ball. The composite metal foam is more than 70% lighter than regular sheet metal - and absorbs 80 times more energy than steel. The body armor is made of composite metal foam and boron carbide ceramic, while the back plate is Kevlar.

Nickel foam is a highly permeable, low-density, three-dimensional reticulated foam metal material, which is a new and rapidly developing material in current materials science. The foam structure gives nickel metal an open-cell structure, which gives it excellent permeability and significant heat transfer and dissipation properties.
Nickel foam is made by electroplating on a skeleton of special polymers with a three-dimensional network structure, such as polyurethane, polyester polyurethane and other special polymers (sponges). After plating, the final metal foam product is made by burning off the internal polymer material and reducing the metal oxides, and is mechanically shaped by chemical heat treatment.
Nickel foam, with its lightweight and electrically conductive properties, is one of the key building blocks of AEM's hydrogen electrolyzers, providing an ideal solution for efficient and sustainable hydrogen production.
