2. List of copper alloys - Wikipedia

   en.wikipedia.org/wiki/List_of_copper_alloys

   Example of a copper alloy object: a Neo-Sumerian "Foundation Nail" of Gudea, circa 2100 BC, made in the lost-wax cast method, overall: 17.5 x 4.5 x 7.3 cm, probably from modern-day Iraq, now in the Cleveland Museum of Art (Cleveland, Ohio, USA) Copper alloys are metal alloys that have copper as their principal component.

3. Copper - Wikipedia

   en.wikipedia.org/wiki/Copper

   Copper. face-centered cubic (fcc) (cF4) Copper is a chemical element; it has symbol Cu (from Latin cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity ...

4. Salt spray test - Wikipedia

   en.wikipedia.org/wiki/Salt_spray_test

   The salt spray test (or salt fog test) is a standardized and popular corrosion test method, used to check corrosion resistance of materials and surface coatings.Usually, the materials to be tested are metallic (although stone, ceramics, and polymers may also be tested) and finished with a surface coating which is intended to provide a degree of corrosion protection to the underlying metal.

5. Aluminium–copper alloys - Wikipedia

   en.wikipedia.org/wiki/Aluminium–copper_alloys

   Aluminium–copper alloys (AlCu) are aluminium alloys that consist largely of aluminium (Al) and traces of copper (Cu) as the main alloying elements.Important grades also contain additives of magnesium, iron, nickel and silicon (AlCu(Mg, Fe, Ni, Si)), often manganese is also included to increase strength (see aluminium-manganese alloys).

6. Copper cladding - Wikipedia

   en.wikipedia.org/wiki/Copper_cladding

   Copper cladding is very durable, lightweight compared to other materials and techniques, and at the end of the building life is also 100% recyclable. Depending on metal prices, copper may be a very cost-effective cladding and roofing material. With good building design, materials choice and craftsmanship, copper roofing or facade cladding may ...

7. List of thermal conductivities - Wikipedia

   en.wikipedia.org/wiki/List_of_thermal_conductivities

   Let K0 is the normal conductivity at one bar (10 5 N/m 2) pressure, Ke is its conductivity at special pressure and/or length scale. Let d is a plate distance in meters, P is an air pressure in Pascals (N/m 2), T is temperature Kelvin, C is this Lasance constant 7.6 ⋅ 10 −5 m ⋅ K/N and PP is the product P ⋅ d/T.
