Bright copper refers to the stripped purple copper wire from cables. It is clean, with no coating or plating on the surface, and no oxidation. In terms of purity, bright copper has almost no impurities, such as rubber. The copper content is above 99.99%. In terms of specifications, the diameter of the bright copper wire should be at least 16 AWG (about 1.29mm in diameter), and in most cases, it is made up of multiple strands of copper wire. The metal recycling rate of bright copper can be as high as 99% or above, with a minimum of 98% or above. Therefore, in the non-ferrous metal waste recycling industry, bright copper is a high-value recycled material, and its price is often close to that of electrolytic copper. Some high-quality bright copper prices can even reach or exceed that of electrolytic copper. It is usually used to refer to clean bare copper wire or clean copper pipes.

The main difference between bright copper and No. 1 copper is the cleanliness of the surface. When inspecting the goods, the surface of bright copper is shiny with a reddish-purple copper luster, while No. 1 copper appears dull.

Common Classification

There is no common classification for bright copper.

Common Sources

Bright copper waste is commonly sourced from the construction industry, electrical industry, infrastructure, manufacturing industry, and so on. Bright copper is often collected in the form of electrical wires and cables. Countries around the world have bright copper production. Globally, the definition and quality of bright copper are basically uniform, especially in international trade and large-scale recycling industries, bright copper is almost the most stable and standardized non-ferrous metal waste.

Value Points

The value points of bright copper lie in its purity, non-oxidation, and surface cleanliness, which are in line with conventional agreements. Such bright copper has the highest value. Purity refers to the use of pure copper, rather than copper alloys, and no attachments; non-oxidation and surface cleanliness refer to the high gloss of the surface, no signs of burning, and no insulation layer.
There is a type of waste called "black bright copper" that has been burned by fire or overloaded with electric current, resulting in a black luster or dark color on the surface. However, this black bright copper does not meet the standard of bright copper, and its market price is about 1% lower than that of normal bright copper.

Processing Methods

Bright copper generally has insulated cables, which need to be stripped before use or sale. Cut the cables into 1-2 meter long segments, and then use a specialized stripping machine with manual stripping to remove the outer skin.
