    en.wikipedia.org/wiki/Circular_mil

    The conversion factor from square mils to circular mils is therefore 4/ π cmil per square mil: 4 π c m i l m i l 2 . {\displaystyle {\rm {{\frac {4}{\pi }}{\frac {cmil}{mil^{2}}}.}}} The formula for the area of an arbitrary circle in circular mils can be derived by applying this conversion factor to the standard formula for the area of a ...

    While CUP and LUP numbers were intended to be comparable to the crushing power of a given pressure, the numbers are not equivalent. Since a longer duration, lower pressure pulse can crush the cylinder as much as a shorter duration, higher pressure pulse, CUP and LUP pressures frequently register lower than actual peak pressures (as measured by a transducer) by up to 20 %.

    en.wikipedia.org/wiki/Resolution_copper

    Resolution Copper (RCM) is a joint venture owned by Rio Tinto and BHP formed to develop and operate an underground copper mine near Superior, Arizona, U.S. The project targets a deep-seated porphyry copper deposit located under the now inactive Magma Mine .

  7. As he climbed up the 500-foot rockface El Matador, wedging small pieces of metal into the rock in the hope they would catch his fall, Jesse Dufton was almost entirely alone.

  8. Oxygen-free copper - Wikipedia

    en.wikipedia.org/wiki/Oxygen-free_copper

    The method of producing OFHC copper ensures an extra high grade of metal with a copper content of 99.99%. With so small a content of extraneous elements, the inherent properties of elemental copper are brought forth to a high degree. In practice the oxygen content is typically 0.001 to 0.003% with a total maximum impurity level of 0.03%.

  9. Mineral-insulated copper-clad cable - Wikipedia

    en.wikipedia.org/wiki/Mineral-insulated_copper...

    Mineral-insulated copper-clad cable is a variety of electrical cable made from copper conductors inside a copper sheath, insulated by inorganic magnesium oxide powder. The name is often abbreviated to MICC or MI cable, and colloquially known as pyro (because the original manufacturer and vendor for this product in the UK was a company called ...
