  2. Oxygen-free copper - Wikipedia

    en.wikipedia.org/wiki/Oxygen-free_copper

    Oxygen-free copper is typically specified according to the ASTM/UNS database. [3] The UNS database includes many different compositions of high conductivity electrical copper. Of these, three are widely used and two are considered oxygen-free: C10100 – also known as oxygen-free electronic (OFE). This is a 99.99% pure copper with 0.0005% ...

    en.wikipedia.org/wiki/Copper_in_heat_exchangers

    Copper has a thermal conductivity of 231 Btu/(hr-ft-F). This is higher than all other metals except silver, a precious metal. Copper has a 60% better thermal conductivity rating than aluminum and has almost 30 times more thermal conductivity than stainless steel. [5]

  4. Copper zinc water filtration - Wikipedia

    en.wikipedia.org/wiki/Copper_zinc_water_filtration

    Copper zinc water filtration is a high-purity brass water filtration process that relies on the redox potential of dissolved oxygen in water in the presence of a zinc anode and copper cathode. It uses dissolved impurities within water as constituent substrate, which are reduced to more physiologically inert compounds.

  5. Copper oxide - Wikipedia

    en.wikipedia.org/wiki/Copper_oxide

    Copper oxide is any of several binary compounds composed of the elements copper and oxygen. Two oxides are well known, Cu 2 O and CuO, corresponding to the minerals cuprite and tenorite, respectively. Paramelaconite (Cu 4 O 3) is less well characterized. [1] Copper oxide may refer to: Copper(I) oxide (cuprous oxide, Cu 2 O) Copper(II) oxide ...

  6. Copper(I) oxide - Wikipedia

    en.wikipedia.org/wiki/Copper(I)_oxide

    Copper(I) oxide or cuprous oxide is the inorganic compound with the formula Cu 2 O. It is one of the principal oxides of copper , the other being copper(II) oxide or cupric oxide (CuO).The compound can appear either yellow or red, depending on the size of the particles. [ 2 ]

  7. Copper(II) oxide - Wikipedia

    en.wikipedia.org/wiki/Copper(II)_oxide

    Copper(II) oxide or cupric oxide is an inorganic compound with the formula CuO. A black solid, it is one of the two stable oxides of copper, the other being Cu 2 O or copper(I) oxide (cuprous oxide). As a mineral, it is known as tenorite, or sometimes black copper.

  9. Oxygen compatibility - Wikipedia

    en.wikipedia.org/wiki/Oxygen_compatibility

    In an oxygen system the presence of oxygen is implied, and in a sufficiently high partial pressure of oxygen, most materials can be considered fuel. Potential ignition sources are present in almost all oxygen systems, but fire hazards can be mitigated by controlling the risk factors associated with the oxygen, fuel, or heat, which can limit the ...
