Copper No. 2 is a widely recycled grade of copper scrap, valued for its versatility despite being of slightly lower quality than Copper No. 1. This category includes items such as tarnished or painted copper pipes, copper with soldered joints, and wiring with some corrosion or residual coatings.
To qualify as Copper No. 2, the material can have slight impurities like solder, paint, or other non-copper elements but must still be at least 94% pure. Its range of sources, from plumbing to industrial equipment, makes it a common and practical option for recycling.
The slightly lower purity means Copper No. 2 fetches a lower price than cleaner grades, but it remains a vital material in the recycling industry. Its applications often include manufacturing and industrial uses, where slight impurities do not impact functionality.
