Scrap glossary
What is Bare bright copper?
Bare bright copper is clean, unalloyed, uncoated copper wire with a shiny surface, no insulation, paint, solder or green oxidation. It is the top grade of copper scrap and earns the highest price per kg.
Wire must usually be thicker than a hair-thin strand; very fine wire and tinned wire are graded lower.
Any burnt insulation residue, tarnish, solder or attached fittings moves it down to No.1 or No.2 copper.
Stripping insulation with a stripping tool rather than burning keeps the copper bright and avoids toxic smoke.
