1. Ultralight
The density is 0.2~0.4g/cm3, which is about 1/10 of the density of aluminum, 1/20 of the density of titanium, 1/30 of the density of steel, 1/30 of the density of steel, and 1/3 of the density of wood.
2. Sound absorption
The new material of foam aluminum can absorb the energy of sound through the vibration of the pore wall to remove noise. The principle of sound-absorbing performance is: after the sound enters the foamed aluminum, diffuse reflection occurs, which interferes with each other, so that the sound energy is converted into heat energy, thereby reducing the noise. Compared with other sound-absorbing materials, the average sound absorption coefficient can reach 0.4~0.52, and the low-frequency absorption performance is excellent.
3. Heat resistance
The new aluminum foam material has high heat resistance. Generally, the dissolution temperature of aluminum alloy is about 560-700 ° C. Even if the single foamed aluminum is heated to 1400 ° C, it will not dissolve, and no harmful gas will be released at high temperature. The non-flammable, non-toxic, heat-resistant and anti-biological corrosion properties of aluminum foam new material products determine that it will not be damaged under the action of combustible oily materials, solutions, ultraviolet rays and radiation.

4. Electromagnetic wave shielding
The skeleton of the new aluminum foam material is connected, which has good shielding for high-frequency electromagnetic waves, and has good electromagnetic absorption and reflection capabilities, which can reduce electromagnetic interference by more than 80%. The electromagnetic shielding performance of foamed aluminum (foamed aluminum) can play a good shielding effect in the space with complicated signals such as office buildings. As the new foamed aluminum material has excellent electromagnetic shielding performance and sound absorption properties, it is suitable for use in the ceiling and walls of telecommunications, electronic instruments, computer rooms, and TV broadcasting equipment rooms as electromagnetic shielding materials.
5. High damping shock absorption and good buffering effect
When the new aluminum foam material is compressed to its yield point, the strain value exceeds the critical strain, the bubble diaphragm is deformed, continuously deformed layer by layer, the bubbles are destroyed, resulting in great compression deformation, the deformation is large and the flow stress level is low, Thereby, the impact energy is absorbed, showing a good buffering effect.
6. Easy to process
The new material of foamed aluminum has good ductility and plasticity, and it is easy to perform mechanical processing such as cutting, drilling, bending and embossing. The new foam aluminum material can be cut into different specifications and sizes with a saw, which can be easily drilled and riveted, can also be bent and embossed, and can be bonded to each other with adhesive. paste.

7. Convenient construction
Due to the light weight of the new foam aluminum material, it can be installed manually without mechanical lifting equipment, which is especially suitable for high-level operations such as ceilings, walls and roofs. Due to the convenience of processing and the possibility of bonding and riveting, it is extremely easy to connect with other structures. Therefore, it is convenient to combine on-site construction and installation.
8. Good surface decoration effect
Using a special process, the surface of the new foam aluminum material can be painted with paint. Painting hardly damages the sound-absorbing effect of the new foam aluminum material, and can improve the surface decoration effect. It can be widely used in the building decoration of shopping malls, hotels, gymnasiums and other venues.
9. Can be used as a sandwich
The new foam aluminum material is bonded with aluminum, copper, titanium and other thin plates on both sides to make a sandwich board. It is a lightweight and high-strength plate. It can be used as a structural material with excellent performance Floor, ceiling, door, wheel guard material and building curtain wall material, roof material.
