Aluminum foam is formed by adding additives to pure aluminum or aluminum alloy profiles and then foaming, and at the same time, it has the characteristics of metal materials and bubbles. It has low relative density, high digestion and impact absorption ability, heat resistance, fire safety performance, corrosion resistance, sound insulation, low thermal conductivity, strong magnetic shielding material, strong aging resistance, filtering ability, easy production and processing, easy installation , High precision molding, can carry out surface spraying. 
Sound-absorbing and sound-insulating materials: Aluminum foam can be used for noise control of light rail stations, elevated highways, underground passages, industrial equipment, and acoustic material rooms, multi-functional conference rooms and other rooms. The sound-absorbing aluminum foam is pasted to the concrete or steel frame structure, and erected on both sides of the overpass and light rail station as a large and medium-sized sound-absorbing wall, which can alleviate the environmental noise of the big city. The sound insulation foam aluminum can be used for noise protection in the main engine room, mechanical equipment, and outdoor construction of the processing plant, and solves many limitations of the widely used sound-absorbing materials such as glass fiber wool and asbestos. 
Aluminum foam can design the comprehensive properties required for the chamber by changing its relative density and pore structure. This is precisely where the style of this distinctive raw material belongs. Therefore, it is widely used in many industries:
