01 Feedstock
Ore, monomer, fibre, mineral or scrap that can legally become Copper.
Copper · The first industrial conductor — wiring, heat exchangers, roofs that go green.
Making Copper is a chain: feedstock, conversion (Chalcolithic / industrial electrorefining 1860s), forming, heat, finish, install.

Ore, monomer, fibre, mineral or scrap that can legally become Copper.
Chalcolithic / industrial electrorefining 1860s
Cast, spin, weave, sinter, foam, laminate or coat — the step that sets anisotropy.
Temper, vulcanise, calcine or dry: skip it and the datasheet is fiction.
Coatings, sizings, facers, galvanizing, anodising, painting.
Fasteners, adhesives, DFT, compression, dryness — site quality is a material property.
Virgin route around Cyprus / global.
Copper has a real loop when sorting is honest.
High-spec grades leave the commodity mill.
Coatings, sprays, casts — the factory is sometimes a jobsite.
Feedstock to installed product.
Energy in, class out.
Melting/softening 1085 °C; conductivity ~400 W/m·K.
Moisture, UV, chlorides, alkalis or oxygen — pick the one that actually kills Copper.
Fire class A1 metal is a starting letter, not a wall rating.
Process energy and scrap quality belong in the carbon passport, not in a footnote.
The iron–carbon workhorse of buildings, ships, rails and tools — endlessly recast.
Overall 66 🥫Light structural metal from Hall–Héroult cells — aircraft skins, cans and façades.
Overall 59 ✈️High specific strength and chloride-tolerant films — airframes, implants and seawater.
Overall 58 🍴Chromium passive films that keep kitchens, chemical plant and façades from rusting like carbon steel.
