Open cell aluminum metal foam is a porous material with numerous bubbles distributed in the metal aluminum matrix.Its special structure determines that it has many special properties that compact metals do not have, such as:
The properties of aluminum foam mainly depend on the pore structure parameters such as porosity, pore diameter, through-hole ratio, pore type and specific surface area, and the pore structure parameters mainly depend on the preparation process.
Foamed aluminum preparation process: solid metal sintering, liquid metal solidification, metal deposition.
Application of Open cell aluminum foam in the automotive industry mainly include lightweight structure, energy absorption structure and heat transfer, such as the structure damping foam aluminum can also be applied to the front longitudinal beam of the car, after the carling, the impact energy absorbing structure between bumper and chassis, internal gear with decoration, fender, top cover plate, the top girder, after partition, connecting rod, piston, control arm, transmission gear, cylinder block, brake cylinder piston, muffler, etc.
