Transparent Aluminum Composite TransAlu Enters Mass Production: 5x Stronger Than Steel, 60% Visible Light Transmission
TransAlu material uses nano-scale alumina whisker reinforcement to achieve 60% visible light transmission with ultra-high strength, with initial applications in bulletproof glass and spacecraft windows.
US materials science company AluClear announced on February 26 that its transparent aluminum composite TransAlu has entered mass production. By embedding nano-scale alumina whiskers in an aluminum matrix, the material achieves 60% visible light transmission and tensile strength exceeding steel by a factor of five.
TransAlu's first commercial customers include Boeing and Lockheed Martin. Boeing plans to use it for next-generation aircraft cabin windows, reducing weight by 40% compared to existing polycarbonate windows. Lockheed Martin is applying it to satellite protective shields.
Currently, TransAlu's production cost is approximately 8 times that of traditional tempered glass, but AluClear expects costs to drop to 3 times within two years as production lines expand.
