Introduction to Copper Scrap Recycling: Lately, environmental issues have garnered the attention of many, and the focus on them has intensified. Now, let's explain the method of sorting copper scrap after it's recycled. 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 wire diameter of not less than 1.6mm.

Pure copper wire and copper cable, free from any color, coating, tin, and alloy. Free from frayed and brittle 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, soldered 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, including various copper scrap. Firstly, this encompasses the scrap, cut-offs, waste materials, semi-finished products, wire materials, and rejects from copper processing factories and copper manufacturing plants; secondly, it also includes discarded copper bare wires and copper tubes, as well as other copper products, but no scale, oil stains, coatings, or the like are permitted; further, the copper scrap should not contain any impurities or copper alloys, and it is also not allowed to have burrs, chips, abrasives, or copper sheets thinner than 1mm.

These are all referred to as brass. The type most commonly collected in the market is called purple brass, with a copper content of around 80%; there is also brass, another commonly collected scrap metal variety. The general brass contains 59% pure copper, with the other components mainly being zinc. This type of copper is also known as brass alloy.
