  2. Beryllium-aluminium alloy - Wikipedia

    en.wikipedia.org/wiki/Beryllium-aluminium_alloy

    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.

    en.wikipedia.org/wiki/Aluminium_compounds

    Aluminium's electropositive behavior, high affinity for oxygen, and highly negative standard electrode potential are all more similar to those of scandium, yttrium, lanthanum, and actinium, which have ds 2 configurations of three valence electrons outside a noble gas core: aluminium is the most electropositive metal in its group.

  5. Aluminium - Wikipedia

    en.wikipedia.org/wiki/Aluminium

    Aluminium (or aluminum in North American English) is a chemical element; it has symbol Al and atomic number 13. Aluminium has a density lower than that of other common metals, about one-third that of steel. It has a great affinity towards oxygen, forming a protective layer of oxide on the surface when exposed to air.

    The mineral industry of Mozambique plays a significant role in the world's production of aluminium, beryllium, and tantalum. [1] In 2006, Mozambique's share of the world's tantalum mine output amounted to 6%; beryllium, 5%; and aluminium, 2%. [1] Other domestically significant mineral processing operations included cement and natural gas. [1]

  8. 7075 aluminium alloy - Wikipedia

    en.wikipedia.org/wiki/7075_aluminium_alloy

    It is one of the most commonly used aluminium alloys for highly stressed structural applications and has been extensively used in aircraft structural parts. [ 2 ] 7075 aluminium alloy's composition roughly includes 5.6–6.1% zinc , 2.1–2.5% magnesium , 1.2–1.6% copper , and less than a half percent of silicon, iron, manganese, titanium ...

  9. Aluminium alloy inclusions - Wikipedia

    en.wikipedia.org/wiki/Aluminium_alloy_inclusions

    Particles of refractory material in contact with aluminium can detach and become inclusions. We can find graphite inclusions (C), alumina inclusions (alpha-Al 2 O 3), CaO, SiO 2, … After some time, graphite refractory in contact with aluminium will react to create aluminum carbides (harder and more detrimental inclusions).
