High-purity Copper Wire Scrap (commonly labeled as Millberry) is defined by a minimum 99.9% copper content, often reaching 99.99% purity. It consists of clean, untinned, uncoated, unalloyed, and unburnt wire, usually 1.6mm or thicker, typically packed in 50kg bales or 1000kg bundles for electrical, melting, and recycling industries.

High-purity copper scrap (99.9%–99.99%) is sold in grades like #1 Millberry (bright, unalloyed wire/pipe), #2 (slightly oxidized/solder-coated), and insulated wire, typically priced based on LME, FOB, or CIF terms. Key details include 99.9% minimum copper content, 0.5–2mm diameters, and clean, uncoated, or mechanically stripped, high-conductivity material.

Key Copper Scrap Grades & Descriptions

#1 Copper Wire (Millberry): Clean, untinned, uncoated, unalloyed copper wire, pipe, and tubing. No insulation, paint, or solder allowed. Often described as "bright and shiny".

#2 Copper Wire: Slightly oxidized, tarnished, or dirty copper, often with small amounts of solder or paint. Must have a minimum of 94%–96% copper content.

Insulated Copper Wire: Various types of insulated wires, typically priced on the estimated copper recovery percentage.

#3 Copper (Roofing/Light): Roofing copper, gutters, or copper with excessive solder or tar, holding a nominal 92% copper content.
