Copper Wire Scrap

Copper wire scrap refers to discarded or recycled copper wires, often from electrical cables, communication lines, or other copper-containing wire products. It's a valuable commodity in the recycling industry, with different grades reflecting purity and condition, directly impacting its value. 

Here's a more detailed breakdown:

Types of Copper Wire Scrap:

Bare Bright Copper:

This is the highest grade, consisting of clean, unalloyed, uncoated copper wire, typically with a bright, shiny appearance. It's highly sought after for its purity and ease of reprocessing. 

#1 Copper:

This grade includes clean, unalloyed copper wire and tubing, potentially with minor oxidation or tarnishing. It may have some fittings or coatings, but should be free of insulation and other impurities. 

#2 Copper:

This grade encompasses a wider range of copper wire scrap, including wire with some oxidation, solder, paint, or other coatings. The copper content is typically lower than #1, around 94-96%. 

Insulated Copper Wire:

This category includes copper wire with various types of insulation, such as plastic or rubber. The value depends on the gauge of the wire and the type of insulation. 

Copper Millberry:

This refers to premium, unalloyed copper wire scrap known for its high purity and is used in various high-quality copper products. 

Factors Affecting Value:

Copper Content:

The percentage of pure copper in the scrap directly affects its value. 

Purity:

Bare bright copper is the most valuable due to its high purity and lack of contaminants. 

Condition:

Clean, uncoated, and unoxidized copper is preferred over scrap with coatings, oxidation, or other impurities. 

Gauge:

Thinner wires may be classified as #2 copper or lower grade, while thicker wires may be more valuable. 

Insulation:

The type and thickness of insulation on insulated copper wire affect its value. 

Common Applications of Copper Wire Scrap:

Recycling and Reprocessing: Copper wire scrap is a valuable resource for recycling into new copper products. 

Electrical Wiring: Reused in new electrical wiring, cables, and other electrical components. 

Plumbing: Recycled copper can be used in plumbing applications. 

Manufacturing: Copper scrap is used in various manufacturing processes.
