  2. 6061 aluminium alloy - Wikipedia

    en.wikipedia.org/wiki/6061_aluminium_alloy

    Electrical properties. Volume resistivity (ρ) 32.5–39.2 nOhm·m. 6061 aluminium alloy ( Unified Numbering System (UNS) designation A96061) is a precipitation-hardened aluminium alloy, containing magnesium and silicon as its major alloying elements. Originally called "Alloy 61S", it was developed in 1935. [ 2]

  3. Corundum - Wikipedia

    en.wikipedia.org/wiki/Corundum

    Corundum is a crystalline form of aluminium oxide (Al 2 O 3) typically containing traces of iron, titanium, vanadium, and chromium. [ 3 ] [ 4 ] It is a rock -forming mineral . It is a naturally transparent material, but can have different colors depending on the presence of transition metal impurities in its crystalline structure. [ 7 ]

  4. Aluminium - Wikipedia

    en.wikipedia.org/wiki/Aluminium

    Aluminium ( 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.

  5. Autoinducer-2 - Wikipedia

    en.wikipedia.org/wiki/Autoinducer-2

    Autoinducer-2 ( AI-2) is a furanosyl borate diester or tetrahydroxy furan (species dependent) that—as the name suggests—is an autoinducer, a member of a family of signaling molecules used in quorum sensing. [ 1] AI-2 is one of only a few known biomolecules incorporating boron. First identified in the marine bacterium Vibrio harveyi, AI-2 is ...

  6. 6060 aluminium alloy - Wikipedia

    en.wikipedia.org/wiki/6060_aluminium_alloy

    6060 aluminium alloy is an alloy in the wrought aluminium-magnesium-silicon family (6000 or 6xxx series). It is much more closely related to the alloy 6063 than to 6061. The main difference between 6060 and 6063 is that 6063 has a slightly higher magnesium content. It can be formed by extrusion, forging or rolling, but as a wrought alloy it is ...

Ultimate tensile strength: 190 to 480 MPa, or 28 to 70 ksi. Thermal Conductivity: 130 to 190 W/m-K. Thermal Expansion: 23 μm/m-K.

  8. Lepidolite - Wikipedia

    en.wikipedia.org/wiki/Lepidolite

    Lepidolite is a lilac -gray or rose-colored member of the mica group of minerals with chemical formula K (Li,Al)3(Al,Si,Rb)4O10(F,OH)2. [ 2][ 3] It is the most abundant lithium -bearing mineral [ 4] and is a secondary source of this metal. It is the major source of the alkali metal rubidium .

  9. 7075 aluminium alloy - Wikipedia

    en.wikipedia.org/wiki/7075_aluminium_alloy

    7075 aluminium alloy. 7075 aluminium alloy ( AA7075) is an aluminium alloy with zinc as the primary alloying element. It has excellent mechanical properties and exhibits good ductility, high strength, toughness, and good resistance to fatigue. It is more susceptible to embrittlement than many other aluminium alloys because of microsegregation ...
