  2. Sheet metal - Wikipedia

    en.wikipedia.org/wiki/Sheet_metal

    Sheet metal is metal formed into thin, flat pieces, usually by an industrial process. Thicknesses can vary significantly; extremely thin sheets are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate, such as plate steel, a class of structural steel. Sheet metal is available in flat pieces or coiled strips.

  3. Continuous casting - Wikipedia

    en.wikipedia.org/wiki/Continuous_casting

    Metal is drained from the tundish through another shroud into the top of an open-base copper mold. The depth of the mold can range from 0.5 to 2 metres (20 to 79 in), depending on the casting speed and section size. The mold is water-cooled to solidify the hot metal directly in contact with it; this is the primary cooling process. It also ...

  4. Copper foil - Wikipedia

    en.wikipedia.org/wiki/Copper_foil

    Copper foil is a thin sheet of copper metal that is widely used in various applications due to its excellent electrical conductivity, malleability, and corrosion resistance. It is an essential material in the electronics industry, especially for manufacturing printed circuit boards (PCBs) and other electronic components.

  5. Coil winding technology - Wikipedia

    en.wikipedia.org/wiki/Coil_winding_technology

    In practice, this is hardly possible at high winding speeds since, e.g., at 18.000 windings per minute, the wire guide for a wire with a thickness of 0.3 mm would need to perform a winding pitch in only 0.7 ms. The problem is amplified by the fact that in practice the ideal wire is never absolutely straight.

  6. Bending (metalworking) - Wikipedia

    en.wikipedia.org/wiki/Bending_(metalworking)

    U-shaped openings cannot be used. Space is left between the sheet and the bottom of the V opening. The optimum width of the V opening is 6 T (T stands for material thickness) for sheets about 3 mm thick, up to about 12 T for 12 mm thick sheets. The bending radius must be at least 0.8 T to 2 T for sheet steel.

  7. Sheet resistance - Wikipedia

    en.wikipedia.org/wiki/Sheet_resistance

    Sheet resistance is a special case of resistivity for a uniform sheet thickness. Commonly, resistivity (also known as bulk resistivity, specific electrical resistivity, or volume resistivity) is in units of Ω·m, which is more completely stated in units of Ω·m 2 /m (Ω·area/length). When divided by the sheet thickness (m), the units are Ω ...

  8. Rolling (metalworking) - Wikipedia

    en.wikipedia.org/wiki/Rolling_(metalworking)

    Rolling (metalworking) In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of ...

  9. Standard wire gauge - Wikipedia

    en.wikipedia.org/wiki/Standard_wire_gauge

    A standard wire gauge. British Standard Wire Gauge (often abbreviated to Standard Wire Gauge or SWG) is a unit for denoting wire size given by BS 3737:1964 (now withdrawn). It is also known as the Imperial Wire Gauge or British Standard Gauge. Use of SWG sizes has fallen greatly in popularity, but they are still used as a measure of thickness ...
