AlBeMet® and E Materials are engineered materials made principally of beryllium. AlBeMet® comes in two formulations, AlBeMet® 140 and AlBeMet® 162, with 40% and 62% beryllium by weight, respectively. Aluminum-beryllium was originally developed for the SR-71 aircraft in the 1960’s and dubbed “LockAlloy”. Aluminum-beryllium under the AlBeMet® trade name was reintroduced in the early 1990’s by Brush Wellman.
