Lightweight Aluminium Metal Foam Sound Absorption for Shipbuilding Applications

Aluminium foam core roof panels in highspeed railway, sound barrier, Pore Size: 0.5-10 mm
Aluminium foam, anew light-weight structural material, is an isotropic highly porous metallic material with a cellular structure.We can provide the world's largest aluminium foam ingots with size(3000mm x 1000mm x H) and can make different products upon cunstomer'srequest.
Aluminium foam prepared by a powder metallurgical method is very efficient in sound absorption, electromagnetic shielding, impact energy absorption, and vibration damping. AluminiumFoams exhibit a reduced conductivity for both heat and electricity.It is non-flammable and form-stable at elevated temperature.The strength is lower than conventional dense aluminum and declines with decreasing density.Aluminium foam,this remarkable metallic material is recyclable and thus environmentally friendly.

2. Product Display
Aluminium foam sandwich panels
It can be combined with metal (aluminum plate, steel plate) and non-metal (wood, marble, carbon fiber, rubber, PE) materials as needed. The layers are bonded by high temperature hot pressing or normal temperature.
With light weight, high specific stiffness, aging resistance, good energy absorption, impact resistance, fire and explosion protection, it can be widely used in indoor and outdoor decoration materials, thermal and acoustic insulation walls and fireproof explosion-proof doors, energy-saving buildings, road sound barriers, ships, high-speed rail, motor train equipment, car structure and engine room sound insulation panels.
3. Application case
Shipbuilding- Noise Reduction in the Engine Room
It can maintain sound absorption performance for a long time than the existing glass wool. It is a non-combustible metal material and will not cause fire. Water proof does not affect sound absorption performance and maintains performance for a long time.
4. about us
Wehavea new production plant and supporting facilities of 40,000 square meters, with more than 130 employees and 39 research and development personnel, including 3 academicians, 15 professors, 10 experts and 11 other technicians. based on the development of aluminum-based materials, our company has increased research on advanced composite materials to achieve cross-border integration andresearch.
