Abstract : The importance of an uninterrupted supply of beryllium metal for the U.S. military and aerospace effort is described and the means by which the single supplier in the western world could meet present and future environmental requirements is examined. Cooperation between government and related activities is suggested. Major recommendations are directed toward upgrading existing facilities and processes for extracting beryllium; use of the gas atomization process in lieu of the current beryllium powder-production method; utilization of near-set-shape technology in making beryllium hardware; establishment of a separate facility for electrorefining, scrap recycling, gas atomization and near-net-shape consolidation; Control of DOD scrap; Improving the beryllium monitoring system; and the continuation of efforts to reduce worker exposure to beryllium particulates. Keywords: Beryllium, Production facilities, Metallurgical extraction techniques, Metallurgical unit processing, Scrap recycling, Health considerations & monitoring, NMAB, Low weight, High strength, Stiffness, Corrosion resistance.
