High-performance aluminum-cerium alloy

By Scott Jenkins |

A newly developed aluminum-cerium alloy is exceptionally stable at high temperatures, and is highly corrosion-resistant, allowing its use in components for advanced engines and for other aerospace, automotive and power-generation applications. Co-developed by Eck Industries (Manitowoc, Wis.; www.eckindustries.com) and Oak Ridge National Laboratory (ORNL; Oak Ridge, Tenn.; www.ornl.gov), with funding from the U.S. Dept. of Energy’s Critical Materials Institute (CMI; Ames, Iowa; cmi.ameslab.gov), the castable Al-Ce alloy is being used to make cylinder heads and pistons for advanced gas and diesel engines, as well as turbocharger components and aircraft engine parts. The addition of cerium to molten aluminum leads to the formation of Al11Ce3 intermetallics that are stable at over 1,000°C which renders the alloy stable at temperatures up to 500°C. Typically, Ce levels of 8–12% are used to develop sufficient high-temperature strengthening. “The alloy’s ability to recover from damage at high thermal loads over time means it can extend the performance range of aluminum alloys beyond where it currently stands,” explains David Weiss, vice president of engineering and R&D at Eck Industries. The aluminum-oxides and cerium-oxides…
