Aluminum Foam Panels
Aluminum foam panel (also known as aluminum foam plate or porous aluminum sheet) is a lightweight, energy-absorbing, and sound-dampening material featuring a unique cellular structure. How to make aluminum foam: it is produced by injecting gas or adding a foaming agent like TiH₂ into molten aluminum, then cooling and solidifying the structure to trap air bubbles inside. The resulting foam is shaped into plates, panels, or blocks, and can optionally be bonded with face sheets such as aluminum skins to form high-strength sandwich panels. Combining low density with mechanical strength and multifunctional properties, aluminum foam panels are ideal for advanced applications in aerospace, automotive, construction, and sound insulation industries.

Main Applications of Aluminum Foam Plate:
Acoustic and Noise Control
Aluminum foam wall panels and foam insulated aluminum panels effective in highways and railway walls noise control applications.Architectural and Interior Design
Aluminum foam sandwich panels and aluminum clad foam roof panels suitable for decorative panels, ceilings, and partitions etc. those functional building facades and interior elements.Automotive, Rail, and Aerospace
Used in crash protection, insulation, and structural reinforcement to reduce weight while enhancing safety and energy absorption. Aluminum foam core roof panels contribute to lightweight roofing solutions in these industries.Industrial and Mechanical Use
Serves as heat- and vibration-resistant panels in machines, enclosures, and equipment with high thermal and mechanical stability. Foam aluminum backed panels provide durable protection and insulation for heavy machinery.Military and Fireproofing
Suitable for blast protection, thermal insulation, and fire-resistant paneling, as it withstands high temperatures and absorbs impact energy.Sustainable Construction
Recognized as a recyclable, lightweight material that supports green building initiatives and energy-efficient design.
