Products Description
Sphere Open-Cell Aluminum Foam
Sphere open-cell aluminum foam is an advanced porous material that combines the benefits of both open-cell and closed-cell structures. It features spherical cavities with regular, circular apertures, where each cavity wall includes small interconnecting holes in six directions. This unique structure avoids straight-through channels, enhancing sound absorption, filtration, and acoustic attenuation.
Key Features
Spherical Cell Structure
Circular and regularly shaped holes with internal interconnections improve acoustic performance by scattering and attenuating sound waves effectively.
High Sound Absorption Efficiency
The non-linear path of the interconnecting pores enhances the material’s ability to absorb and reduce noise, making it ideal for soundproofing applications.
Customizable Parameters
Noise reduction performance can be optimized by adjusting:
Sphere diameter: 2–11 mm
Wall hole diameter: 0.5–2 mm
Material thickness
Processing technique
Superior Mechanical Strength
The uniform distribution and regular shape of the spherical pores provide excellent energy absorption and impact resistance, making it suitable for damping and protective applications.
Applications
Vehicle Body Panels
Used in automotive, rail, and aerospace industries for lightweight sound insulation and vibration damping.
Mechanical Equipment
Effective in noise reduction and acoustic shielding in heavy machinery and industrial environments.
Advanced Energy Absorption Components
The regular pore structure and spherical design contribute to superior crashworthiness and energy dissipation, ideal for impact protection systems.
