Foamed aluminum is made of metal aluminum or aluminum alloy after adding additives during reprocessing, and then undergoes a foaming process, and has the characteristics of both metal and air bubbles. Metal aluminum or aluminum alloy is put into the foaming box when it is molten, and gas is injected to form bubble cavities. After the liquid metal solidifies, a new material—aluminum foam. It has low density, high impact absorption ability, high temperature resistance, strong fire resistance, corrosion resistance, sound insulation and noise reduction, low thermal conductivity, high electromagnetic shielding, strong weather resistance, filtering ability, easy processing, easy installation, and high forming accuracy , Can carry out surface coating. Aluminum foam, also known as foamed aluminum, is used in a wide array of applications and industries.Sound-absorbing and sound-insulating materials: Aluminum foam can be used for urban light rail, elevated highways, underground tunnels, noise control of mechanical equipment, and improvement of acoustic rooms, multi-functional halls and other indoor sound effects. Sound-absorbing foamed aluminum is pasted on concrete or steel structures, and erected on both sides of viaducts and light rails as large sound-absorbing walls, which can reduce urban traffic noise. Sound-insulating aluminum foam can be used for noise isolation in factory computer rooms, machinery and equipment, and outdoor construction sites, solving many limitations of widely used sound-absorbing materials such as glass wool and asbestos.1. Ultra-light characteristics, the foam density is 0.2~0.4g/cm3, 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 1/30 of the density of wood 1/3. 2. Sound-absorbing performance. Aluminum foam can absorb sound energy through the vibration of the air hole wall to eliminate sound. 3. Heat resistance. Generally, the melting temperature of aluminum alloy is about 560-700°C. Even if the single foam aluminum is heated to 1400°C, it will not dissolve, and it will not release harmful gas at high temperature. 4. Electromagnetic wave shielding performance. Aluminum foam has good shielding effect on high-frequency electromagnetic waves, which can reduce electromagnetic interference by more than 80%. 5. Plasticity, which can be divided into three specifications: large aperture, medium aperture, and small aperture. Each specification is divided into single-sided opening, double-sided opening, and natural casting state (double-sided closed), diversified specifications It can provide designers with more space to play in diversified designs.Looking closer, it is easy to find that aluminum foam is the characteristic of metal + bubbles, which is very obvious. Therefore, it also has the advantages of very superior metal materials, and because of the air bubbles, it will have the characteristics of ultra-light, sound absorption, heat resistance, and electromagnetic wave shielding.Anna Yang Export Manager sales9@dzxtech.cn   +86 13270911653 Changzhou DZX/DLX Alloy.
