Introduction to Copper Scrap Recycling: Lately, environmental issues have gained significant attention and are being increasingly prioritized. 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 alloys. Surface is non-oxidized, free of burrs, with a diameter of not less than 1.6mm.

Pure copper wire and copper cable without any color, coating, tin, alloy, or roughness. Free from frayed and brittle copper wire.

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-burnt wire, insulated copper wire, and excessive fine wire must be removed properly if necessary.

Four, including various copper scrap. First, it covers the waste materials, cut-offs, off-grade materials, semi-finished products, wire materials, and scrap from copper processing factories and copper manufacturing plants; secondly, it includes scrapped copper wire and copper pipes, as well as other 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 thinner than 1mm.

These are all referred to as purple copper. The type most commonly recovered in the market is called purple mixed copper, with copper content around 80%; brass is also a frequently recovered type of scrap metal. General brass contains 59% pure copper, known as 59 brass, with the other components mainly being zinc; this type of copper is also called brass mixed copper.
