#1 copper wire: the clean scrap grade.

What #1 copper looks like when we buy it

These are real loads Sonny bought — not stock photos. #1 copper comes in as clean stripped wire, nests, cuttings, and clean unalloyed fittings.

The Berry spec, in plain English

The trade code name for #1 copper wire is Berry: clean, untinned, uncoated, unalloyed copper wire and cable, free of brittle burnt wire. Note what the spec does not require: brightness. Tarnished or dulled-but-clean wire lands here by design. So do bare-bright rejects — stripped welding cable, for example, is bright but far too fine-stranded for Barley, and falls to #1. The test is cleanliness, not shine.

What #1 looks like in the real world

Stripped cable with a dulled, weathered finish. Heavy wire gone brown from sitting in a yard. Clean busbar drops with a patina. And bright, fine-stranded wire — welding lead, battery cable, portable power cord — stripped clean. It's a mixed-looking pile, but everything in it shares one thing: clean, uncoated, unalloyed copper with nothing burnt or brittle in the mix.

Where #1 comes from

Demo tear-outs and panel upgrades (weathered but clean wire), electrician cutoffs and scrap ends, welding shops (spent leads), and motor and generator tear-down wire that comes out clean. Anywhere copper worked hard and came out dull but honest, #1 is the likely grade.

The line between #1 and bare bright

Three tests separate them: is it shiny? — dull wire stops at #1. Is it thick enough? — about 12 AWG and larger, in yard practice. Is it coarse-stranded? — hair-fine strands fail even when bright. Fail any one test and bright-looking wire steps down a rung. That stepping-down is exactly why sorting pays: the shiny thick stuff in one pile, the dull and fine stuff in another. See what qualifies as bare bright for the top-shelf test.

What keeps wire in #1

#1 earns its grade by what it isn't: no burnt or brittle wire, no solder, no tinning or plating, no oil, and no hardware left attached. Cut the ends and clips off, keep the soldered and painted pieces in their own pile, and your clean wire grades like it should. One contaminated handful can drag a whole load down to #2 copper — sort before you haul.
