Chemistry:Lockalloy

From HandWiki

Lockalloy is an alloy that consists of 62% beryllium and 38% aluminum. It was used as a structural metal in the aerospace industry because of its high specific strength[1] and stiffness.[2] The alloy was first developed in the 1960s by the Lockheed Missiles and Space Company.[3][4] The material was used in the Lockheed YF12 and LGM-30 Minuteman missile systems. In the 1970s production difficulties limited the material to a few specialized uses and by the mid 1970s Lockalloy was no longer commercially available.[5][2] In 1990, Materion Beryllium & Composites re-introduced the material into the commercial marketplace as a powder-sintered composite under the trade name of AlBeMet.[2]
