NASA’s Marshall Space Flight Center originally developed a high-performance piston alloy to meet U.S. legislative restrictions on vehicular exhaust hydrocarbon emissions. NASA 398 aluminum alloy exhibits excellent tensile and fatigue strength at elevated temperatures. NASA 398 alloy also offers superior wear resistance, surface hardness, dimensional stability, and lower thermal expansion compared to conventional aluminum alloys.

NASA 398 has been used in mass production, and has enabled innovative commercial products. MSFC’s Technology Transfer Office is seeking new licensees that may also benefit from its adoption.

NASA’s Technology Transfer Program offers commercial licensing agreements to ensure its pioneering research finds secondary uses that benefit the economy, create jobs, and improve quality of life.
