Quick answers
Is Copper non-combustible?
Declared reaction class in this atlas: A1 metal. Assemblies still need resistance tests.
Does Copper insulate?
Thermal mark 6/100 versus the atlas. Conductivity note: ~400 W/m·K.
What is the density band?
8.96 g/cm³
How is it made?
Origin story: Chalcolithic / industrial electrorefining 1860s (Cyprus / global).
Can it be recycled?
Circularity mark 78/100 — editorial, route-specific.
Typical melting or failure heat?
1085 °C

Copper 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.

Timeline
c. 5000 BCENative copper
Hammered native copper in the Balkans and Near East precedes true smelting.
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.
