2. Copper tubing - Wikipedia

   en.wikipedia.org/wiki/Copper_tubing

   Rigid copper is a popular choice for water lines. Rigid or "Hard" copper tubing is generally referred to as "pipe". Copper "piping" is referred to by nominal pipe size, or the inner diameter. It is joined using a solder/sweat, roll grooved, compression, or crimped/pressed connection. Rigid copper, rigid due to the work hardening of the drawing ...

3. List of copper alloys - Wikipedia

   en.wikipedia.org/wiki/List_of_copper_alloys

   The discovery and exploitation of the Bolivian tin belt in the 19th century made tin far cheaper, although forecasts for future supplies are less positive. There are as many as 400 different copper and copper alloy compositions loosely grouped into the categories: copper, high copper alloy, brasses, bronzes, cupronickel, copper–nickel–zinc ...

4. Copper conductor - Wikipedia

   en.wikipedia.org/wiki/Copper_conductor

   Copper is the electrical conductor in many categories of electrical wiring. [3][4] Copper wire is used in power generation, power transmission, power distribution, telecommunications, electronics circuitry, and countless types of electrical equipment. [5] Copper and its alloys are also used to make electrical contacts.

5. Pipe (fluid conveyance) - Wikipedia

   en.wikipedia.org/wiki/Pipe_(fluid_conveyance)

   The history of copper pipe is similar. In the 1930s, the pipe was designated by its internal diameter and a 1 ⁄ 16-inch (1.6 mm) wall thickness. Consequently, a 1-inch (25 mm) copper pipe had a 1 + 1 ⁄ 8-inch (28.58 mm) outside diameter. The outside diameter was the important dimension for mating with fittings.

6. Oxygen-free copper - Wikipedia

   en.wikipedia.org/wiki/Oxygen-free_copper

   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. [1][2] Oxygen-free copper is a premium grade of copper that has a high level of conductivity and is virtually free from ...

7. Copper in heat exchangers - Wikipedia

   en.wikipedia.org/wiki/Copper_in_heat_exchangers

   Copper heat exchangers are important in solar thermal heating and cooling systems because of copper's high thermal conductivity, resistance to atmospheric and water corrosion, sealing and joining by soldering, and mechanical strength. Copper is used both in receivers and in primary circuits (pipes and heat exchangers for water tanks) of solar ...
