2. Monel - Wikipedia

   en.wikipedia.org/wiki/Monel

   Monel is a group of alloys of nickel (from 52 to 68%) and copper, with small amounts of iron, manganese, carbon, and silicon. Monel is not a cupronickel alloy because it has less than 60% copper. Stronger than pure nickel, Monel alloys are resistant to corrosion by many aggressive agents, including rapidly flowing seawater. They can be ...

3. Beryllium copper - Wikipedia

   en.wikipedia.org/wiki/Beryllium_copper

   Beryllium copper (BeCu), also known as copper beryllium (CuBe), beryllium bronze, and spring copper, is a copper alloy with 0.5–3% beryllium. [1] Copper beryllium alloys are often used because of their high strength and good conductivity of both heat and electricity. [2] It is used for its ductility, weldability in metalworking, and machining ...

   Example of a copper alloy object: a Neo-Sumerian foundation figure 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.

6. Non-ferrous metal - Wikipedia

   en.wikipedia.org/wiki/Non-ferrous_metal

   In metallurgy, non-ferrous metals are metals or alloys that do not contain iron (allotropes of iron, ferrite, and so on) in appreciable amounts.. Generally more costly than ferrous metals, non-ferrous metals are used because of desirable properties such as low weight (e.g. aluminium), higher conductivity (e.g. copper), [1] non-magnetic properties or resistance to corrosion (e.g. zinc).

7. Bezel (jewellery) - Wikipedia

   en.wikipedia.org/wiki/Bezel_(jewellery)

   Other types of bezel settings, less used in modern jewelry, are swivel bezels where the bezel, perhaps just formed of a stone with a metal rod through it, can rotate, and box bezels, where a "box" or cage forms the bezel, often sitting on the main ring hoop, and perhaps open at the top where there is a stone.
