Introduction to Copper Scrap Recycling: Lately, environmental issues have garnered significant attention and are becoming increasingly important. Let's explain how copper scrap is categorized after recycling, and take a look at the classification process together.

One, bare, uncoated, and alloy-free pure copper wire. Surface is non-oxidized, free of burrs, with a wire diameter of not less than 1.6mm.

Pure copper wire and copper cable without impurities, color, coating, tin, or alloys. Free from fibers and fragile, burned copper wire.

Three, including non-alloyed copper wire containing impurities, copper content of 96% (not less than 94%). Copper wire with excessive lead and tin plating, soldered copper wire, brass and bronze wire, excessive oil, waste steel and non-metals, brittle over-fired wire, insulated copper wire, and excessive fine wire should be removed properly if necessary.

Four, including various copper scrap. First, this includes scrap copper, cut-offs, defective materials, semi-finished products, wire materials, and waste products generated from copper processing factories and copper processing manufacturing plants; secondly, it also covers obsolete copper wires and pipes, and other copper products, but should not contain scale, oil stains, coatings, etc.; thirdly, the copper scrap should not contain any impurities or copper alloys, nor should it include burrs, shavings, filings, or copper sheets with a thickness less than 1mm.

The materials mentioned above are all referred to as brass. The type most commonly recovered in the market is called purple mixed brass, which contains about 80% copper. Another commonly recovered scrap metal is brass, typically the 59% copper content 59 brass, with the remaining components mainly zinc, which is also known as mixed brass.
