Bare Bright, Copper Wire Recycling No. 1 , 2, 3 Copper, Copper Recycling Insulated Copper Wire, Brass and Copper Recycling

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.

Copper Bearing Scrap

Consists of miscellaneous copper-containing skimmings, grindings, ashes, irony brass and copper, residues, and slag. Shall be free of insulated wire, copper chlorides, and unprepared tangled material.

Brass Recycling

Yellow Brass

Contains a minimum of 60% copper and maximum 5% iron. Shall be free of insulated wire, grindings, electrotype shells and non-metallics.

Copper Recycling

Red Brass

Consists of red brass valves, machinery. Shall be free of semi-red brass castings. No piece to measure over 12” over any part or weigh more than 100 lbs.

Brass Recycling

Brass Clips

Consists of brass alloy stamping or sheet material. Purchase agreed by the buyer and seller based on the alloy type of the material.

Brass and Copper Recycling

Brass Turnings

Consists of scrap borings or turnings alloyed with copper, tin, bismuth, and zinc. Turnings shall be unmixed and less than 0.2% alloyed lead.

Brass Turnings Recycling

Brass Shells

Consists of clean fired 70/30 brass shell cases free of primers and any other foreign material. All shells must be sufficiently mutilated to prevent reuse and reloading.

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.

Example Sales Descriptions & Specifications

Premium Millberry Wire: 99.99% purity, electrolytic grade, 0.25mm–2mm diameter, low oxygen, high conductivity.
