Introduction to Copper Scrap Recycling: Lately, environmental issues have garnered significant attention and are becoming increasingly important. Now, let's explain the methods of sorting copper scrap after recycling. How is it categorized? Let's take a look together.

One, pure copper wire, bare, uncoated, and without alloy. Surface is free of oxidation and burrs, with a diameter of not less than 1.6mm.

Pure copper wire and copper cable without color, coating, tin, or alloy. Free from bristles and brittle copper wire that has been overheated.

Section 3: Includes non-alloyed copper wire containing impurities, with a 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, scrap steel and non-metals, brittle over-fired wire, insulated copper wire, and excessive fine wire must be removed properly if necessary.

Four, includes various copper scrap. Firstly, this encompasses the scrap, cut-offs, waste materials, semi-finished products, wire materials, and defective items of pure copper generated from copper processing factories and copper manufacturing plants; secondly, it also covers discarded pure copper bare wires and copper pipes, as well as other pure copper products, but they must be free from scale, oil stains, coatings, etc.; further, the copper scrap should not contain any impurities or copper alloys, and it is also not allowed to have 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 collected in the market is called mixed bronze, with an approximate copper content of 80%. Brass is another widely collected type of scrap metal. Standard brass typically contains 59% pure copper, with the remaining components mainly being zinc. This type of copper is also known as mixed brass.
