Properties of aluminum foam
1. Ultra light
The density of 0.2-0.4/cm3 is 1 / 30 of iron, 1 / 10 of aluminum and 1 / 4 of wood
2. Sound absorption
The porous structure has good sound absorption. The aluminum foam sound absorbing material can be used for building interior decoration (walls, ceiling, floor), railways, highways, factories, mechanical equipment and other places. Suitable for large noise occasions (which can replace the original harmful sound absorbing materials), perforating the closed cell aluminum foam plates can be made into sound absorbing boards with high sound absorption rate. When the opening rate is 1% ~ 3%, the sound absorption rate is higher. The sound absorption rate measured by standing wave method is 40% ～ 80% in the range of 1000Hz to 2000Hz.
Soundproof effect of aluminum foam: sandwich board made of foam aluminum, made of sound insulation board, 20mm thick, sound insulation: 20～40dB。
3.fire resistance
It is a metal material with 100% fire resistance and does not produce toxic gases in case of fire. According to the experience of the National Center for quality supervision and measurement of fireproof building materials, the flame performance of the product meets the requirements of A1 level. According to GB8624-2012, the combustion performance of the product reaches a (A1) level. Heat resistant / non flammable characteristics: aluminum foam is softened at 600 degree high temperature and is a non combustible material.
Thermal insulation performance: the thermal conductivity of aluminum foam is 0.25~0.62W/m.K, which is equivalent to marble and has better thermal insulation performance.
Thermal stability: linear expansion coefficient of aluminum foam 1.934*10 ℃ ， Similar to concrete, it is not easy to deform when heated.
4. Energy absorption
The porous structure can absorb energy effectively, and it can absorb energy in high impact deformation rate. Sb5 grade is the first in China
5. Wave absorption
The aluminum foam screen has the power to absorb electromagnetic waves. It can be used in military (stealth material), TV station, hospital and other electromagnetic radiation occasions,
Electromagnetic shielding: the electromagnetic shielding (below 200MHz) is 90dB, with excellent electromagnetic shielding performance.
6. Environmental protection
Aluminum foam is non-toxic, tasteless and dust-free. It produces no harmful gas in the fire, and 100% recycle and reuse.
Nontoxic: aluminum foam is a composite material composed of metal and air holes. It is non-toxic and does not escape toxic gas at high temperature.
The main chemical composition of aluminum foam is aluminum alloy and its oxide. It can be used without any pollution to the environment.
7. Mechanical properties:
Mechanical properties: compressive strength: 3-17mpa; Bending strength: 3 ~ 15MPa; Tensile strength: 2-7 MPa;
Cushioning performance: energy absorption can reach 8J/cm3 ~ 30J/cm3. Foam aluminum can absorb energy through deformation. It is an excellent energy absorbing material for impact energy.
Damping performance: tested by Institute of solid state physics, Chinese Academy of Sciences,The internal friction factor Q-1 of foam aluminum reached 6. × 10-3
8. Machinability:
Foamed aluminum is widely used in various fields. It is based on a porous lightweight silver white metal material, which has the characteristics of easy processing. It can be sawn, cut, planed, and milling. It is easy to be processed into plates, bars, bars and various special-shaped parts.
9. Weather resistance:
Corrosion resistance: exposed in marine atmospheric environment for one year without obvious abnormality; Under the accelerated corrosion condition, there was no abnormality in the spray salt spray test for two years; It shows that the corrosion resistance of aluminum foam is very good.
Non moisture absorption: the moisture absorption rate of foam aluminum is 0%. There is no moisture absorption phenomenon, and the acoustic performance will not be reduced due to moisture
Product application field
Because of its many special properties, aluminum foam can be widely used in aerospace, aviation, high-speed trains, city rail trains, shipbuilding, high speed rail, construction, tunnel and noise barriers along the way. It has light weight, high absorption, high shock absorption, high absorption energy, high electromagnetic shielding performance, excellent heat insulation, high temperature resistance and non inflammable fire characteristics. It has unique environmental friendliness.
