Sphere Open Cell Aluminum Foam

Sphere open-cell aluminum foam with the characteristics of both of open-cell and closing cell aluminum foam, Hole shape is circular, aperture relative rules, hole wall open a small round hole connected to the ball, to six directions, avoid the square hole, is advantageous to the amount of sound absorption, sound filter, and attenuation.

In actual use, can get the ideal effect of noise reduction through design to the sphere size (diameter of 2-11 mm), wall hole size (0.5 2 mm in diameter), and thickness and making process control.

Sphere open-cell aluminum foam for the current domestic aluminum foam sound-absorbing material at the top of the product, suitable for all kinds of the vehicle body and mechanical equipment deadened the noise reduction;

Due to the sphere uniform distribution, pore shape, the same rules of hole wall, also longer than absorb energy, has excellent impact resistance.
