Boeing and Lockheed Martin have signed agreements with Aerofoam Metals to explore aerospace and defence applications for the Canadian company's foamed-aluminium material Aerometal. Ontario-based Aerofoam says Aerometal has the same physical properties as aluminium, but is 16% lighter. When placed in a mould and heated, the material will foam and expand to fill the mould. Potential uses include impact absorption, blast mitigation, sound insulation and electrical shielding.
