Foam Aluminum: An innovative solution for diverse industry verticals

Jul 7th 2015 at 2:39 AM

The spongy-looking foam aluminum is best recognized for its soundproof, energy absorption and vibration damping abilities. The very nature of this metal enables it to protect electromagnetic radiation. The foamed aluminum is considered eco-friendly also as it is recyclable. And since it has amazing tensile, mechanical, thermal and acoustic strength, its applications across aerospace, naval, automobile, construction, and science and research fields are noteworthy. If you have to buy this metal foam Panel , you can check its quality on some of these following parameters:

· Cell type (open or closed)

· Density

· Chemical construction

· Heat conductivity

· Tensile power

· Soundproof ability

· Electromagnetic wave protection capability

· Compressive strength

Aluminum foam is a type of metal featuring random, typically roundish pores spread all over it. These pores can be open or closed. Both these constructions have their own characteristics, hence it is essential to determine the purpose of use first so that you can accordingly take your decision. Just to make your choice slightly easy, closed foamed aluminum panel, aluminum foam board, aluminum foam bulkheads and aluminum foam partitioning walls can absorb impact energy and has great stiffness; that’s why their use is widespread in the railway, construction and aviation sectors. The open cell foams, on the other hand, are used in heat exchangers, light weight optics and flow diffusion because of their air ventilation and acoustic properties.

A reputed foamed aluminum factory uses advanced methods to manufacture high-end metal foam for different needs. In the foam making process, usually gas bubbles are injected into liquid metal so that these remain in the surface after the metal is cool. However, if the viscosity of the liquid metal is increased keeping in mind the pressure and temperature conditions, the bubbles do not make it to the surface and solidify much before. For this, either a foaming agent is used or gas is injected directly. Mostly, titanium hydride or calcium carbonate types of compounds are used as foaming agent while working with aluminum. According to experts, titanium hydride is costly and also risky to handle.

Whatever process is used in making this, one thing is clear that aluminum foam energy absorption, vibration stifling, soundproofing and such other properties make it a favorite choice across different industries. Some people may argue when glass wool and asbestos like materials are already doing well when it comes to noise absorption then why this new material should be given preference.

The reason for this is simple. Aluminum foam can offer better tensile strength, temperature resistance, and low moisture absorption. It’s an extra light porous material and its power of absorbing sound in urban settings and improving the acoustics in multi-purpose settings is excellent. Today, its application in workshops, construction sites and machines is much appreciated.
