  3. Electronic color code - Wikipedia

    en.wikipedia.org/wiki/Electronic_color_code

    A 2.26 kΩ, 1%-precision resistor with 5 color bands (), from top, 2-2-6-1-1; the last two brown bands indicate the multiplier (×10) and the tolerance (1%).. An electronic color code or electronic colour code (see spelling differences) is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, diodes and others.

  4. Tempering (metallurgy) - Wikipedia

    en.wikipedia.org/wiki/Tempering_(metallurgy)

    Tempering is a heat treatment technique applied to ferrous alloys, such as steel or cast iron, to achieve greater toughness by decreasing the hardness of the alloy. The reduction in hardness is usually accompanied by an increase in ductility, thereby decreasing the brittleness of the metal.

    en.wikipedia.org/wiki/Gray_iron

    Malleable iron. Wrought iron. Micrograph of grey cast iron. Gray iron, or grey cast iron, is a type of cast iron that has a graphitic microstructure. It is named after the gray color of the fracture it forms, which is due to the presence of graphite. [ 1] It is the most common cast iron and the most widely used cast material based on weight.

    A common application of the 25-pair color code is the cabling for the Registered Jack interface RJ21, which uses a female 50-pin miniature ribbon connector, as shown in the following table. The geometry of the pins of the receptacle (right hand image) corresponds to the pin numbers of the table.

  8. Cast iron - Wikipedia

    en.wikipedia.org/wiki/Cast_iron

    Cast iron is a class of iron – carbon alloys with a carbon content of more than 2% and silicon content around 1–3%. [ 1] Its usefulness derives from its relatively low melting temperature. The alloying elements determine the form in which its carbon appears: white cast iron has its carbon combined into an iron carbide named cementite, which ...

  9. Steel casting - Wikipedia

    en.wikipedia.org/wiki/Steel_casting

    Steel casting. Steel casting is a specialized form of casting involving various types of steel cast to either final/net or near-net shape. Steel castings are used when iron castings cannot deliver enough strength or shock resistance. [ 1]
