c. 5000 BCE
Native copper
Hammered native copper in the Balkans and Near East precedes true smelting.
铜 did not arrive as a finished commodity. Chalcolithic / industrial electrorefining 1860s around Cyprus / global still explains who makes it and which tests it sits in.
Ten dated points, five eras and three milestones below are the spine — not a complete industrial history.

c. 3500 BCEBronze age
Tin bronzes raised hardness for tools and weapons.
c. 2500 BCECyprus mines
The island’s name is entangled with the metal’s European word-hoard.
1660sFalun / Cornish
Early modern European mining scaled sheet and coinage.
1865Electrorefining
James Elkington’s electrorefining made 99.9% Cu for telegraphy.
1870sEdison / Siemens wiring
Buildings and grids became copper-shaped.
1913IACS
Annealed copper defined the conductivity standard.
1982US penny zinc
Coinage debased; plumbing and wire stayed copper.
2000sData-centre busbars
High-current DC and EV inverters revived thick copper.
2020sCu crunch talk
Grid and EV forecasts collide with mine permitting, not with chemistry.

Knowing this timeline is how to read a mill certificate without treating 铜 as timeless.
