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.

According to the International Resource Panel's Metal Stocks in Society report, the global per capita stock of aluminium in use in society (i.e. in cars, buildings, electronics, etc.) is 80 kg (180 lb). Much of this is in more-developed countries (350–500 kg (770–1,100 lb) per capita) rather than less-developed countries (35 kg (77 lb) per ...
Aluminium (British and IUPAC spellings) or aluminum (North American spelling) combines characteristics of pre- and post-transition metals. Since it has few available electrons for metallic bonding, like its heavier group 13 congeners, it has the characteristic physical properties of a post-transition metal, with longer-than-expected interatomic ...
Similarly to the nucleophilic carbon center in the carbene, the lone pair on the aluminium center binds to the first azide equivalent. Nitrogen gas is liberated. With the second equivalent of azide, a five-member ring is formed. Aluminium (I) systems undergo reactions with azides in the same fashion as carbenes. [10]
6105 aluminium alloy is an alloy in the wrought aluminium-magnesium-silicon family (6000 or 6xxx series). It is one of the least common of the alloys in this series. While most wrought aluminium alloys are covered by multiple standards (from any mixture of ASTM, EN, ISO, and national standard bodies), 6105 is only dealt with in ASTM B221: Standard Specification for Aluminum and Aluminum-Alloy ...
Typically, recyclers in the U.S. can expect aluminum can prices to hover around $0.56, on average, per pound of cans. As the table below illustrates, though, the monetary reward will mostly depend ...
Straumsvik aluminum smelter, operated by Rio Tinto Alcan in Iceland. Aluminium smelting is the process of extracting aluminium from its oxide, alumina , generally by the Hall-Héroult process . Alumina is extracted from the ore bauxite by means of the Bayer process at an alumina refinery .
