Ultra-lightweight fireproof and anti-collision aluminum foam 80mm thick
Product Description
Closed cell aluminum foam is a new type of ultra-light structure-function integrated material. Due to its unique porous structure, closed-cell aluminum foam exhibits many outstanding properties, such as high specific strength/stiffness, energy absorption, sound absorption, sound insulation, damping and vibration damping, heat-resistant and heat preservation, electromagnetic shielding and so on. Because of this, closed-cell aluminum foam has a wide range of applications in the automotive industry, transportation facilities, construction materials and other fields.
Product Advantage
1, light weight: density of 0.2-0.4g/cm3, density of 10% -40% of the metal aluminum; density of 0.2-0.4g/cm3, about 1/10 of the density of aluminum, titanium density of 1/20, and steel density of more than 1/30;
2, fire and heat resistance: closed-cell aluminum foam insulation effect and marble is comparable to a high degree of heat resistance, the general dissolution temperature of the aluminum alloy in the 500-700 degrees Celsius or so, even if the foam aluminum heated to 1400 degrees Celsius also does not dissolve;
3, sound insulation and noise reduction: through-hole aluminum foam sound absorption coefficient of up to 0.8; aluminum foam can be through the vibration of the pore wall to absorb the sound energy, used for anechoic, remove noise. The noise reduction coefficient is close to 0.9%.
4, ductility and plasticity: easy to cut, drill and glue; can be bent into the required shape by molding;
5, non-combustible and heat-resistant: good corrosion and weather resistance, low moisture absorption, no aging;
6, easy to install: can be connected and fixed by mechanical methods or directly with screws, can also be pasted on the wall or ceiling with adhesive;
7, electromagnetic shielding: aluminum foam sheet belongs to the superior grade of electromagnetic shielding materials, RF 200MHz electromagnetic waves, shielding effectiveness of 90dB. thickness of 20mm iron plate, with foam, its shielding electromagnetic waves for 50dB. 20mm foam aluminum alone, shielding electromagnetic waves for 90dB, the weight of 1/50 of the iron plate;
Product Application
1. Automobile protection: but its bending ratio height can reach 1.5 times of steel. Whether Japanese low-strength longitudinal beam cars, or Europe and the United States high-strength longitudinal beam cars, need to solve the problem of collision avoidance, foam aluminum impact beam to meet the requirements of absorbing the kinetic energy of the impact, caused by the automobile body of the big change;
2. Marine manufacturing industry: common tugboat, cargo ship engine room noise reduction needs, engine room acoustic lining, spacer, hatch, high-performance deck, lightweight and high-strength ship structural parts;
3. Aerospace: the density of aluminum foam is only about 0.1 and 0.4 times that of metallic aluminum. In the current aerospace field, before the aerospace field, the cellular structure material application is relatively When a wide range.
