Scrap Copper (encompassing bare bright copper wire scrap Millberry, heavy copper scrap Birch/Cliff, high-purity copper granules, and clean copper tubing) serves as a vital recycled non-ferrous raw material for global copper smelting, wire rod manufacturing, brass/bronze alloy ingots, and secondary metallurgical production. Delivering exceptional electrical and thermal conductivity, high recycling yield, and identical metallurgical performance to primary copper, recycled copper scrap is essential for sustainable manufacturing.

As a trusted global manufacturer and supply chain partner, XQJ Metal (xqjmetal.com) provides a consistent, high-purity supply of industrial scrap copper tailored for remelting, foundry casting, and international trade. Processed in strict accordance with ISRI (Institute of Scrap Recycling Industries) standards, our copper scrap undergoes rigorous sorting, magnetic separation, and quality control to ensure minimal impurities and zero radiation.

Core Scrap Copper Categories & ISRI Specifications:

• Bare Bright Copper Wire Scrap (Millberry / ISRI Berry): Clean, unalloyed, uncoated bare copper wire (minimum 16 gauge / 1.6 mm thickness) boasting a minimum copper purity of 99.9%. Free of insulation, tin coatings, oxidation, or solder joints.

• Heavy Copper Scrap (Candy / Birch / Cliff): Unalloyed clean heavy copper solids, thick plates, busbars, and clean copper tubing. Free of excessive scale, iron attachments, solder joints, or foreign oil residue.

• Copper Granules & Chopped Cable Scrap (ISRI Clove/Cobra): Mechanically processed high-purity copper granules derived from stripped electrical cables. Features uniform particle size, fast furnace charging, and high thermal efficiency during remelting.

• Brass & Bronze Alloy Scrap: Recycled brass solids, radiator scrap, valve bodies, and turnings categorized for secondary copper alloy ingot manufacturing and precision sand casting.

Frequently Asked Questions (FAQ):

Q: What is the copper purity level and standard for Millberry bare bright copper wire scrap?

A: Our Millberry copper scrap maintains a minimum copper purity of 99.9% Cu (conforming to ISRI Berry specifications). It consists of clean, uncoated, unalloyed copper wire with a gauge thicker than 1.6 mm, completely free of varnish, insulation, oxidation, or tinning.

Q: How is the copper scrap packaged and loaded for international container shipping?

A: We compress copper scrap into high-density hydraulic bales (approx. 500–800 kg each) securely strapped on pallets, or pack them in 1-ton heavy-duty jumbo bags. This maximizes payload efficiency up to 25 metric tons per 20ft container and facilitates fast forklift unloading.

Q: Do you provide third-party SGS or CCIC inspection and radiation test certificates?

A: Yes, every XQJ Metal copper scrap shipment can be inspected by independent third-party agencies (such as SGS or CCIC) to certify chemical purity, net weight, and zero-radiation safety prior to container sealing.

Q: What is the MOQ and commercial trade terms for wholesale copper scrap export?

A: Our standard MOQ for copper scrap export is 20 to 25 metric tons (one full 20ft container). We support flexible international trade terms including FOB, CFR, and CIF.
