Beryllium-aluminum alloy an alloy that consists of 62% beryllium and 38% aluminum, by weight, corresponding approximately to an empirical formula of Be 2 Al. It was first developed in the 1960s by the Lockheed Missiles and Space Company, who called it Lockalloy, [1] [2] and used as a structural metal in the aerospace industry because of its high specific strength [3] and stiffness.

Many gases have toxic properties, which are often assessed using the LC 50 (median lethal concentration) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.
