Copper scrap primarily consists of refined or unrefined copper materials recovered from electrical, plumbing, and industrial waste. It may contain traces of other metals such as tin, zinc, or nickel depending on its source. The purity of the scrap determines its recyclability and value in the market.
Pure copper boasts an electrical conductivity rating of over 100% IACS (International Annealed Copper Standard), making it the preferred choice for electrical wiring and components. Its high thermal conductivity, ductility, and resistance to corrosion also make it ideal for mechanical and industrial applications. Importantly, copper retains all its physical and chemical properties even after multiple recycling cycles — a key factor in supporting the circular economy.
At Sakthi Metals, we deal with a broad spectrum of copper scrap grades as per ISRI (Institute of Scrap Recycling Industries) standards. The main categories include:
Millberry Copper (ISRI Code: BIRCH / BERRY)
Bright, uncoated, unalloyed copper wire with a minimum purity of 99.9%. Commonly used in electrical and electronic manufacturing industries.
Berry / Candy Copper
High-grade, clean copper wire and bus bars, free from insulation, coatings, and impurities. Highly sought after by refineries for remelting.
Birch / Cliff Copper
Mixed unalloyed copper scrap containing various grades of uncoated and coated wire. Ideal for refining and secondary copper production.
Copper Cathode Scrap
Sheets or plates of pure copper used in high-conductivity applications. Often recovered from industrial manufacturing waste.
Copper Turnings and Granules
By-products of machining and cutting operations, processed and refined to meet remelting specifications.
Mixed Copper Scrap
A blend of different copper forms such as pipes, sheets, and insulated wires, sorted according to purity and grade.
Recycling copper scrap is a highly efficient process that significantly reduces energy use and greenhouse gas emissions compared to primary production. At Sakthi Metals Waste Trading LLC, we ensure that our copper recycling follows the highest standards of quality and environmental responsibility.
Collection and Sorting:
Copper scrap is sourced from trusted suppliers, industries, and demolition sites across the globe. It is then sorted manually or using automated systems based on grade and purity.
Cleaning and Stripping:
Non-metallic materials such as insulation, plastic, and rubber are removed from wires and cables to ensure clean, high-quality copper output.
Shredding and Separation:
The scrap is shredded into smaller pieces for easier handling. Advanced magnetic and air separation techniques remove ferrous contaminants.
Melting and Refining:
Clean scrap is melted in furnaces at controlled temperatures. Refining processes eliminate impurities and adjust the copper composition to desired specifications.
Casting and Supply:
The molten copper is cast into cathodes, rods, or billets for reuse in manufacturing sectors like electrical, construction, and automotive industries.
Through these systematic steps, Sakthi Metals ensures maximum material recovery, minimal waste generation, and adherence to international environmental standards.
Recycled copper is a cornerstone of industrial and economic development. Its wide range of uses includes:
Electrical Wiring and Cables: Power lines, transformers, and communication systems.
Construction Materials: Roofing, plumbing, and heating systems.
Electronics Manufacturing: Circuit boards, connectors, and semiconductors.
Automotive Industry: Radiators, electric vehicle components, and braking systems.
Renewable Energy: Solar panels and wind turbine generators.
Because recycled copper performs identically to newly mined copper, it provides industries with a cost-effective and eco-friendly raw material.
