Copper & Specialties
Copper Wire
Copper wire is a widely used electrical conductor made from high-purity copper. It is valued for its excellent conductivity, flexibility, and durability, making it suitable for power transmission, electronics, and industrial wiring.
Key Features of Copper Wire
- High conductivity: Enables efficient electrical flow with minimal energy loss
- Types: Available as solid wire for strength or stranded wire for flexibility
Typical Specifications
- Copper purity: Typically 99.9%–99.95% Cu
Copper Millberry
Refers to high-grade #1 bare bright copper wire scrap, with copper purity typically ranging from 99.95% to 99.99%. This material consists of clean, untinned, uncoated, and unalloyed copper, usually sourced from stripped electrical wire or cable. Due to its excellent electrical conductivity, it is highly valued in the recycling industry and is commonly used in the manufacturing of new electrical and electronic components.
Key Characteristics and Specifications
- Purity: Copper content of 99.95%–99.99%
- Appearance: Bright and shiny; free from insulation, oxidation, solder, paint, and other contaminants
- Size: Typically consists of wire with a diameter of 0.2mm–0.5mm; certain premium classifications may require wire diameters of ≥1.2mm
