Description
1. Basic Product Information
- Product Name: 3D Open-Cell Foam Aluminum
- Core Definition: A type of foam aluminum with interconnected internal pores, combining metallic properties and a porous structure. Its core advantages lie in excellent sound absorption performance and fire resistance.
2. Core Performance Parameters
2.1 Structural Parameters
- Pore Size: 0.5-1.0mm (corresponding to pore size specifications of 10PPI, 20PPI, 30PPI; customization available)
- Porosity: 70%-90%
- Open-Cell Rate: 98% (Note: Marked based on the product’s actual performance to ensure alignment with application characteristics)
- Purity: 93%
- Standard Thickness: 10mm
2.2 Functional Performance
- Sound Absorption Performance: The noise reduction coefficient (NRC) is ＞0.75. Sound absorption is achieved through the abrupt cross-sections formed by internal micro-channels and pores, as well as a large number of side-branch Helmholtz resonance cavities. Its sound absorption effect on medium and low frequencies is significantly better than that of traditional materials. (Sound Absorption Mechanism: Breaks through the limitations of conventional viscous sound absorption and heat conduction sound absorption, and enhances resonant sound absorption.)
- Fire Resistance: Fire rating reaches Class A1 (the highest fire rating, suitable for scenarios with high safety requirements).
3. Standard Specifications (Length × Width × Thickness)
- 100mm × 100mm × 10mm (pore size: 20PPI)
- 50mm × 50mm × 10mm (pore size: 20PPI)
