Introduction to Copper Scrap Recycling: Lately, environmental issues have gained a lot of attention, and it's only getting more so. Now, let's discuss the methods of sorting copper scrap after recycling. How is it categorized? Let's take a look together.

One, Pure copper wire, uncoated and without alloys, featuring no oxidation on the surface, no fuzz, and a wire diameter of no less than 1.6mm.

Pure copper wire and copper cable, including clean, colorless, uncoated, unwelded, and non-alloyed types. Free of burrs and fragile copper wire that has been overheated.

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

Four, includes various pure copper waste materials. First, this encompasses the scrap, cut-offs, waste materials, semi-finished products, wire materials, and rejects from copper processing plants and copper manufacturing facilities; secondly, it also covers discarded pure copper bare wires and copper tubes, as well as other pure copper products, but no scale, oil stains, coatings, or the like are permitted; further, the waste copper materials must not contain any impurities or copper alloys, and should not include burrs, chips, filings, or copper sheets with a thickness less than 1mm.

The materials mentioned above are all referred to as bronze. The type commonly recovered in the market is called mixed bronze, with a copper content of around 80%; brass is also a frequently recovered type of scrap metal. Standard brass typically contains 59% pure copper, with the remaining components mainly being zinc, and this type of copper is also known as mixed brass.
