What is Scrap Copper?
Scrap copper is any item or material composed of at least 95% copper that is no longer usable in its original form. It includes items such as wires, cables, pipes, sheet metal, offcuts from manufacturing processes, etc. Copper scrap can come in a variety of shapes and sizes and often contains other metals such as lead due to the recycling process.
By breaking down these materials into smaller components one can save energy and resources by reusing them instead of creating new products from raw material sources.
Different Types of Scrap Copper
By having a good understanding of the different types of scrap copper available, individuals and businesses can identify which components they need to recycle and how best to process them for reuse. Here are the most common types:
Bare Bright Copper
Bare bright copper is the purest form of copper scrap and can be identified by its bright, shiny appearance. It usually comes in the form of thin wires or cables that have been stripped of insulation and other non-metallic materials. Bare bright copper generally contains no other metals such as lead, which makes it an ideal choice for those looking to recycle their scrap copper efficiently.
Copper Pipe
Copper pipe is a type of scrap copper that has been cut into smaller pieces, usually to fit certain specifications. It often comes from plumbing systems, electrical wiring projects, and more. Copper pipe is identifiable due to its reddish hue and can be recycled just like bare bright copper if it meets the necessary purity requirements.
Copper
Copper is a type of scrap copper that has been stripped of non-metallic elements such as paint, plastic, and insulation. It is then separated into two categories depending on yield quality – either bright or dark. Bright copper is shiny and contains no other metals; whereas dark copper may contain some lead or other impurities.
This type of copper scrap is the most valuable as it requires less processing than other forms and can be turned back into its original form with relative ease. It can usually be identified by its wire form and reddish hue which makes it one of the top choices for recycling companies looking to get the most value from their scrap metal. Once processed, this type of scrap can be used to create new products.
Copper
Copper is a type of scrap copper that is usually found in the form of sheets, tubing, or castings. This type of copper has been processed to remove non-metallic elements such as paint and insulation but may still contain some lead or other impurities. It is not as valuable as bare bright copper or #1 copper due to its lower purity levels and the need for further processing before it can be reused.
Light Copper (AKA grade #3 copper)
It is a type of copper which is usually used in plumbing applications. This copper is softer and more malleable than its counterparts allowing it to be handled during the installation process. Light Copper is also very resistant to corrosion, making it ideal for underwater or damp environments.
Its light color helps it blend into many home designs, while still providing an attractive look. Light copper can often be recycled which makes this material environmentally friendly as well. For these reasons, it is becoming increasingly popular as a choice among homeowners looking for piping materials that will last a long time and are easy to install.
Insulated Wire
Insulated wire is a type of wiring material that consists of a conductive metal core or cable surrounded by protective insulation. This insulation can be made from many different materials, such as plastic, rubber, PVC, and fiberglass. Insulated wires are used for a variety of electrical purposes in both residential and commercial applications.
They are designed to protect against electric shock, prevent sparks from arcing between the wire and surrounding objects, provide insulation to keep heat away from sensitive components and reduce electromagnetic interference. In addition to offering safety benefits, insulated wires help maximize signal transfer efficiency by minimizing resistance along the length of the wire. This copper type comes in various sizes for different uses and can be bought pre-insulated or you can purchase separate insulating materials to be applied around the wire.
