  2. List of copper alloys - Wikipedia

    en.wikipedia.org/wiki/List_of_copper_alloys

    Copper alloys are metal alloys that have copper as their principal component. They have high resistance against corrosion . Of the large number of different types, the best known traditional types are bronze , where tin is a significant addition, and brass , using zinc instead.

  3. Copper conductor - Wikipedia

    en.wikipedia.org/wiki/Copper_conductor

    An example of a copper alloy conductor is cadmium copper wire, which is used for railroad electrification in North America. [5] In Britain the BPO (later Post Office Telecommunications) used cadmium copper aerial lines with 1% cadmium for extra strength; for local lines 40 lb/mile (1.3 mm dia) and for toll lines 70 lb/mile (1.7 mm dia). [23]

  4. Copper - Wikipedia

    en.wikipedia.org/wiki/Copper

    Copper used in buildings, usually for roofing, oxidizes to form a green patina of compounds called verdigris. Copper is sometimes used in decorative art, both in its elemental metal form and in compounds as pigments. Copper compounds are used as bacteriostatic agents, fungicides, and wood preservatives.

  5. Copper tubing - Wikipedia

    en.wikipedia.org/wiki/Copper_tubing

    Soft (or ductile) copper tubing can be bent easily to travel around obstacles in the path of the tubing. While the work hardening of the drawing process used to size the tubing makes the copper hard or rigid, it is carefully annealed to make it soft again; it is, therefore, more expensive to produce than non-annealed, rigid copper tubing.

  6. Oxygen-free copper - Wikipedia

    en.wikipedia.org/wiki/Oxygen-free_copper

    The CuOFP capsule used as overpack for spent nuclear fuel disposal in the KBS-3 concept (Swedish version). Oxygen-free copper (OFC) or oxygen-free high thermal conductivity (OFHC) copper is a group of wrought high-conductivity copper alloys that have been electrolytically refined to reduce the level of oxygen to 0.001% or below.

  7. Cupronickel - Wikipedia

    en.wikipedia.org/wiki/Cupronickel

    Cupronickel or copper–nickel (CuNi) is an alloy of copper with nickel, usually along with small quantities of other metals added for strength, such as iron and manganese. The copper content typically varies from 60 to 90 percent. (Monel is a nickel–copper alloy that contains a minimum of 52 percent nickel.)

  8. Magnet wire - Wikipedia

    en.wikipedia.org/wiki/Magnet_wire

    Inductor made with magnet wire wound around a toroidal core. Magnet wire [1] or enameled wire is a copper or aluminium wire coated with a very thin layer of insulation.It is used in the construction of transformers, inductors, motors, generators, speakers, headphones, hard disk head actuators, electromagnets, electric guitar pickups, and other applications that require tight coils of insulated ...

  9. LME Copper - Wikipedia

    en.wikipedia.org/wiki/LME_Copper

    LME Copper contracts trade on the London Metal Exchange, which began trading in the metal at the start of the exchange in 1877. [1] The contracts require physical delivery of the asset for settlement, and deliverable assets for the contracts are 25 tonnes of Grade A copper cathode. The contracts prices are quoted in US dollars per tonne.
