What is Aluminium foam?
Aluminum metal foam, also known as the aluminum foam sheet, is made by adding additives to pure aluminum or aluminum alloy through a foaming process. Simply put, it is a metal plate with N holes
According to the different control of foamed aluminum in the production process, there will be surface styles such as single-sided open cell, double-sided open cell, and closed-cell.
At the same time, foamed aluminum can also have a variety of colors. In addition to the true color of aluminum, like other aluminum plates, the color of foamed aluminum can be rendered colorful through metal treatment processes such as spraying.
Thanks to the special production process, there are more styles of foamed aluminum and a wider range of applications. It can be used to cover exterior walls, interior walls, ceilings, floors, and stairs required for architectural decoration. area.

Performance Characteristics of Aluminum Metal Foam
The aluminum foam density is about 1/5~1/10 of pure aluminum, 1/20 of iron, and 1/4 of wood and plastic. Its bending stiffness is 1.5 times that of steel. The unique lightweight panel is very suitable as a building skin, and the aluminum foam panels are completely recycled, which is very environmentally friendly.
Before being used in the field of architectural decoration, foamed aluminum began to be used in the field of automobile manufacturing, which can reduce the weight of vehicles and improve fuel efficiency.
Thanks to the strong weather resistance of foamed aluminum, the cost-effectiveness of aluminum foam is still very high in terms of building life and service life, as well as maintenance costs.
According to relevant laboratory data, aluminum foam has been exposed to the ocean atmosphere for one year without any obvious abnormality. The surface can be sprayed with anti-corrosion treatment to further improve the anti-corrosion ability
The aluminum metal foam has a moisture absorption rate of 0.0%, no moisture absorption, and will not reduce the acoustic performance due to moisture.
Tested by the National Fireproof Building Material Quality Supervision and Inspection Center, the combustion performance has reached A1 level. At the same time, the linear expansion coefficient of foamed aluminum is 19.34*107°C, which is equivalent to concrete and is not easily deformed when heated.
As a foam material, foamed aluminum has excellent thermal insulation effect. The insulation effect of closed-cell aluminum foam is equivalent to that of marble, and the weight is less than half of marble.
At the same time, it has a good acoustic function. The sound insulation coefficient of closed-cell aluminum foam is above 0.9. The sound absorption coefficient of through-hole aluminum foam can reach 0.8.
For office buildings, a space with more cluttered signals can have a good electromagnetic shielding effect. When the electromagnetic wave frequency is between 2.6-18GHZ, the electromagnetic shielding ability of foamed aluminum can reach 60-90dB.
Aluminum Foam Applications
Aluminum foam is a new type of light metal material produced by using bionic structure principles and using aluminum alloy foam. It is light and strong, has low density, high specific strength, and has sound insulation and noise reduction, electromagnetic shielding, energy absorption buffering, and resistance. Many excellent properties such as combustion and explosion protection are widely used in aerospace, equipment manufacturing, transportation facilities, building decoration, civil panels and other fields.
How to Make Aluminum Foam?
Aluminum foam is a lightweight, porous material that has many useful properties, such as high strength-to-weight ratio and good thermal and acoustic insulation. Here is a general process for making aluminum foam:
Preparing the aluminum: The first step is to melt the aluminum using a furnace or other heating method. Once the aluminum is melted, any impurities or gases must be removed to ensure a high-quality foam.
Adding a foaming agent: A foaming agent is added to the molten aluminum to create gas bubbles within the liquid metal. There are several different types of foaming agents that can be used, including titanium hydride, calcium carbonate, and aluminum powder.
Casting the foam: The foamed aluminum is then poured into a mold or shaped using other methods, such as extrusion or injection molding. The foam can be made in a variety of shapes and sizes, depending on the application.
Cooling and solidification: Once the foam is cast, it must be allowed to cool and solidify. The cooling process can be controlled to achieve a desired level of porosity and density.
Finishing: The foam may require some finishing, such as trimming or sanding, to achieve the desired shape and surface finish.
Overall, the process for making aluminum foam can be complex and requires specialized equipment and expertise. However, the resulting material can be extremely useful for a wide range of applications.
