Product Details
Pore ​​shape: The hole connecting part of the sphere opening type is composed of small round holes in the bubble chamber and the bulkhead, which is equivalent to hollowing out dense aluminum with a plurality of tightly packed hollow spheres, forming a structure that can allow gas or liquid substances to penetrate the aluminum. The space through which the body flows, therefore, aluminum foam is also called metal sponge. The bubble chamber of the sphere open-cell aluminum foam is spherical, relatively regular, and the spheres are arranged very closely. Small round holes are opened on each bulkhead to connect other spheres, and they open to 6 directions, with a connectivity rate of more than 90%. .

The structure in which the spheres are connected by pores is conducive to the absorption and filtration of energy. Since it is not a straight hole, the energy will undergo repeated conversion between the sphere and the pores when passing through, and the flow rate and flow rate will undergo progressive attenuation changes.

Product Features
For sound absorption and noise reduction, the ideal application effect can be obtained through the design and process control of the size of the sphere (diameter 2-13mm), the size of the wall hole (diameter 0.5-4mm), the thickness of the hole wall and the thickness of the plate. Bulk density: about 0.8g/.

Product Usage
For impact resistance and energy absorption, the circular close-packed structure has unparalleled advantages: spherical bubble chambers, round wall holes, and relatively regular bulkheads, making the spherical open-cell type more resistant to energy absorption and impact resistance. Compared with the closed-cell type produced by gas foaming and slow-release foaming, it has a longer buffer time and no rebound when receiving impact energy. Compared with other types of open-cell aluminum foam, the compressive (44Mpa) and bending (27Mpa) strengths of the spherical open-cell type are much higher, which is significantly improved.
