Product Description:

Aluminum foam is a new concept metalmaterial which is foamed in sponge shape after melting aluminum ingot withvarious chemical ingredients and has many bubble layers inner structure.

Porous material is much lighterthan original one, which is the characteristic of porous. And, it improves the ability of energy absorption and reduces the abilityof thermal and electrical conductivities than original metal materials. Inaddition, porous material has wide applications as well as excellent ability ofsound absorption and permeability of liquid, air, etc.

Aluminumfoam, a metal itself, can be applied to aerospace aviation required the  thermostability over 200℃. It is a 100% recyclableeco-friendly material and absolutely will not produceharmful substances no matter in the process of producing, using or abandoning.


Density is 0.2~0.4g/cm3 (Aluminium1/10,Iron1/30, and Wood 1/4)


Porous structure has a good soundabsorption.

Aluminum foam sound-absorbing materialcan be used in the inner decoration of buildings (walls, ceiling and floor),railway, highway, factories, mechanical equipment and any other fields.

Suitable for noisy place.


100%non-flammability and no toxic gas released when burning.

Non-combustibility TEST verified to be qualified. <KIMM; IMO A.799 (19)>

Ⅰgrade Non-flammability TEST ofaluminum foam surface verified to be qualified. <KICT; KS F2271>


Porous structure can effectively absorbenergy.

Have a great effect on energyabsorption after a high impact.

Firstly acquired the national SB5class (Guard rail shock-absorber)

Electromagnetic wave shielding ability

Aluminum foam has a function ofabsorbing electromagnetic wave

Widely used in military (stealth materials),TV station, hospital and any other electromagnetic shielding places.


100% recyclable Aluminum foam is nonpoisonous, odorless andharmless, no toxic gas released when burning.

Aluminumfoam can be produced by recycled aluminum and its scraps.

Q:What is the best sound insulation decoration
In some places due to the weight of the problem, can not use brick or other wall approach, can only use light steel keel gypsum board approach is recommended to add a layer of gypsum board outside the hardness of a relatively high cement board, this Cement board appearance and gypsum board the same (size is also similar), but the hardness is much higher than the gypsum board, is a good sound insulation material, should pay attention to the construction process, especially the part of the gap must be sealed.
Q:Can do those sound insulation materials Under the wooden floor
Damping noise board, rockwool noise board,
Q:What is the structure of the sound barrier?
The board is the main sound insulation component, which through the high-strength spring clip to be fixed in the H-shaped column groove, the formation of sound barrier. Sound barrier design has been more fully considered the elevated highways, urban light rail, subway wind load, traffic vehicle impact safety and all-weather open air corrosion problems. It is beautiful, beautiful, easy to install, low cost, long service life, especially for high-speed highway and urban light rail, the use of subway noise, is the ideal modern city noise noise reduction facilities.
Q:What is the principle of noise board?
A kind of transmission of sound is called intermediation. That is, from one medium through the critical contact surface of the two media into another medium, at this time, the transmission of acoustic energy is the transmission of vibration amplitude. Cross-media propagation, the greater the difference between the density of the two media, the greater the loss of sound energy. In practice, the air is the human normal space, so the greater the density of the material with the density of the material is generally a very high density material (much lower than the air density of the material in addition to vacuum, really not much), that is, Can be regarded as sound insulation material. The higher the density, the better the sound insulation. Such materials made of sheet metal, known as sound insulation board. Sound insulation method is to use a soundproof material to isolate the sound source from the surrounding environment, so that the radiation noise can not be directly transmitted to the surrounding area, so as to achieve the purpose of noise control. The essence of sound insulation is to minimize the sound from the sound source radiation, commonly used measures are sound insulation and sound insulation structure.
Q:What is the soundproofing between the bedroom and the bedroom?
Practice has proved that the noise of various frequencies have a good absorption effect.
Q:Home improvement sound insulation materials which?
Construction is very convenient and fireproof soundproof material.
Q:How easy it is for the soundproof wall to be soundproof
The thickness of the noise wall is determined by the size of the noise source. The larger the noise source is, the more the thickness of the noise wall will be increased. Generally, the thickness of the noise wall will be sacrificed at about 5-10 cm.
Q:What soundproof material can be attached to the window
In order to prevent their own home TV, stereo, piano interference neighbors, you can in the TV, audio background wall with ultra-thin glass sound-absorbing cotton, local soft bag and fabric sofa also has a good sound absorption effect.
Q:What is the best choice for sound insulation?
Damped soundproof vibration pad
Q:What can be placed on the floor noise?
Floor noise insulation materials are mainly used for KTV, disco, factories, home theater and other places with strong noise source sound insulation. Sound insulation, light, black finish, tensile strength; construction convenience, low cost; flame retardant, moisture, moth; in high temperature and low temperature conditions should not be broken and soft
