2.Electrical characteristics of materials.
The conductivity of aluminum foam material is much smaller than that of solid aluminum material.
The thermal conductivity of aluminum foam is much smaller than that of solid aluminum, which is about 0.1 – 0.2 times of solid aluminum.
In addition, the foam aluminum also has a rigid, non flammable, not easy to oxidation, not easy to produce aging, good weather resistance, good recovery and regeneration characteristics.
Excellent electromagnetic shielding performance: when the electromagnetic wave frequency is 2.6-18GHZ,
the electromagnetic shielding capacity of aluminum foam can reach 60-90dB.
3.Corrosive characteristics materials.
Corrosion resistance: in Marine atmospheric environment exposure for a year, no obvious abnormality:
accelerated corrosion condition, the water salt spray experiment 2 years without exception.Show that corrosion resistance of aluminum foam is very good.
To do spraying anti-corrosion surface treatment, further improve the corrosion resistance.
4.Acoustic characteristics.
20-40dB
5.Vibration characteristics.
Strong absorption of impact energy, energy efficiency can basically reach more than 50%, the platform area energy efficiency of 80% to 90%, can be a good absorption of external energy, reduce the impact of damage.
Foam aluminum damping mainly refers to its good absorption of shock or impulse energy capacity. Shock absorption or impact resistance is of particular importance to transport vehicles. Foam aluminum is better than other foam materials to absorb the impact energy capacity, is isotropic in performance, is the ideal buffer material.
High damping performance and impact energy absorption rate: damping capacity of metal aluminum 5-10 times.
Aluminum foam with a porosity of 50% is capable of absorbing more than 2.5MJ/M3C of energy when it has a variant of 84%.
