New Aluminum Material-Aluminum Foam Application Summary

Aluminum Foam [https://www.beihaicomposite.com/aluminum-foam-tag/] Characteristics

Ultra-lightness

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.

Sound Absorbability

Aluminum foam [https://www.beihaicomposite.com/about-us/] can be used to muffle and reduce noise by absorbing sound energy through the vibration of the pores' walls.

Heat resistance

It has high heat resistance; the general dissolution temperature of aluminum alloy is about 560-700. Single-foam aluminum does not dissolve even when heated to 1400 and does not release harmful gases at high temperatures.

Electromagnetic wave shielding

Aluminum foam has good shielding against high-frequency electromagnetic waves, and can reduce electromagnetic interference reduce more than 80%.

Aluminum foam is most widely used in automobile industry: it can be used to manufacture automobile bumpers, bumper beams, and other energy-absorbing parts, which can effectively absorb the energy in the collision and reduce the damage to the drivers and passengers. It can also be used for thermal and acoustic insulation of the automobile engine compartment to reduce the engine noise into the car and improve the comfort of the car.

Aerospace: Due to its lightweight and high strength, it can be used to manufacture airplane wings and fuselage structural parts to reduce the weight of airplanes and improve fuel efficiency. At the same time, its good thermal insulation performance also helps to maintain the temperature stability inside the aircraft.

Construction: As a heat-insulating material for the exterior walls of buildings, it can effectively block external heat from being transmitted to the interior and reduce the energy consumption of buildings. It can also be used to make sound-absorbing ceiling and sound-insulating wall panels to improve the acoustic performance of buildings and create a quiet indoor environment.

Electronic equipment: With good electromagnetic shielding performance, it can be used to manufacture the shell of electronic equipment to prevent external electromagnetic interference and ensure the normal operation of the equipment.

Performance of aluminum foam

Aluminum foam is a new type of lightweight functional, structural integration material with both metal and bubble characteristics, and its special structure determines that it has many special properties that dense metal does not have. Such as:

1, ultra-lightweight nature: foam density of 0.2 ~ 0.4g/cm3, the density of only 10% to 40% of the metal aluminum, titanium density of 5%, 4% of the density of steel, as well as wood density of 30%.

2, electromagnetic wave shielding performance, foam aluminum has a good shielding effect on high-frequency electromagnetic waves, which can reduce electromagnetic interference reduction of more than 80%.

3, high bending resistance: its bending resistance is 1.5 times that of steel;

4, heat-resistant performance, the general aluminum alloy dissolution temperature is 560-700 or so, a single foam aluminum, even if heated to 1400 , also does not dissolve, and at high temperatures, does not release harmful gases;

5, good Sound insulation performance (closed cell) and sound-absorbing performance (through-hole): aluminum foam can be used to muffle sound by absorbing the sound energy through the vibration of the pore wall. Sound wave frequency between 800~4000Hz, closed-cell foam aluminum sound insulation coefficient of 0.9 or more; sound wave frequency between 125 ~ 4000HZ, through the foam aluminum sound absorption coefficient of up to 0.8.

6, not moldy, not easy to dirty. Indoor use does not change color, and outdoor rainy areas can be free of cleaning.

7, corrosion resistance: aluminum itself has good corrosion resistance, and the porous structure of aluminum foam makes it more resistant to corrosion, which can be used in harsh environments.

At the same time also has a small density, high impact absorption capacity, filtering capacity, easy processing and installation, forming precision, and other advantages, but also surface coating.

Future applications of aluminum foam

Aluminum foam can be designed by changing its density and pore structure to the desired comprehensive performance. It has a lightweight and high strength, sound absorption and noise reduction, fire performance, corrosion resistance, low thermal conductivity, high electromagnetic shielding, easy processing and installation, beautiful texture, and other characteristics.

There are so many "home skills" foam aluminum in the actual design will be applied to where to go?

Aluminum foam is used in many fields, including construction, aerospace, transportation, electronics, energy, and so on. It can be used as a structural material, thermal insulator, energy absorber, filter, sound and vibration absorber, and more. At the same time, the sustainable and environmentally friendly properties of aluminum foam make it one of the options that can be used as an alternative to traditional materials.
