  2. Aluminum building wiring - Wikipedia

    en.wikipedia.org/wiki/Aluminum_building_wiring

    The use of larger gauge stranded aluminum wire (larger than #8 AWG) is fairly common in much of North America for modern residential construction. Aluminum wire is used in residential applications for lower voltage service feeders from the utility to the building. This is installed with materials and methods as specified by the local electrical ...

  3. American wire gauge - Wikipedia

    en.wikipedia.org/wiki/American_wire_gauge

    AWG is colloquially referred to as gauge and the zeros in thick wire sizes are referred to as aught / ˈ ɔː t /. Wire sized 1 AWG is referred to as "one gauge" or "No. 1" wire; similarly, thinner sizes are pronounced "x gauge" or "No. x" wire, where x is the positive-integer AWG number. Consecutive AWG wire sizes thicker than No. 1 wire are ...

  4. Osmium - Wikipedia

    en.wikipedia.org/wiki/Osmium

    Osmium is a hard, brittle, blue-gray metal, and the densest stable element—about twice as dense as lead. The density of osmium is slightly greater than that of iridium ; the two are so similar (22.587 versus 22.562 g/cm 3 at 20 °C) that each was at one time considered to be the densest element.

  5. IEC 60228 - Wikipedia

    en.wikipedia.org/wiki/IEC_60228

    Comparison of SWG (red), AWG (blue) and IEC 60228 (black) wire gauge sizes from 0.03 to 200 mm² to scale on a 1 mm grid – in the SVG file, hover over a size to highlight it. In engineering applications, it is often most convenient to describe a wire in terms of its cross-section area, rather than its diameter, because the cross section is directly proportional to its strength and weight ...

  6. Wire gauge - Wikipedia

    en.wikipedia.org/wiki/Wire_gauge

    Each notch is stamped with a number, and the wire or sheet, which just fits a given notch, is stated to be of, say, No. 10, 11, 12, etc., of the wire gauge. The circular forms of wire gauge measurement devices are the most popular, and are generally 3 + 3 ⁄ 4 inches (95 mm) in diameter, with thirty-six notches; many have the decimal ...

  7. Ductility - Wikipedia

    en.wikipedia.org/wiki/Ductility

    Gold is extremely ductile. It can be drawn into a monatomic wire, and then stretched more before it breaks. [12]Ductility is especially important in metalworking, as materials that crack, break or shatter under stress cannot be manipulated using metal-forming processes such as hammering, rolling, drawing or extruding.

  8. Electrical conductor - Wikipedia

    en.wikipedia.org/wiki/Electrical_conductor

    The flow of negatively charged electrons generates electric current, positively charged holes, and positive or negative ions in some cases. In order for current to flow within a closed electrical circuit, one charged particle does not need to travel from the component producing the current (the current source) to those consuming it (the loads).

  9. Standard wire gauge - Wikipedia

    en.wikipedia.org/wiki/Standard_wire_gauge

    A standard wire gauge. The British Standard Wire Gauge, often referred to as the Standard Wire Gauge or simply SWG, is a unit used to denote wire gauge (size) as defined by BS 3737:1964, a standard that has since been withdrawn. It is also known as the Imperial Wire Gauge or British Standard Gauge. Although its use has significantly declined ...
