Description of Copper Scrap Copper scrap refers to discarded copper materials that can be recycled and reused. This material is a significant source of copper for manufacturing new products, conserving natural resources, and reducing environmental impact. Copper scrap is available in various grades, each differing in purity and physical characteristics. Recycling copper scrap is energy-efficient compared to producing new copper from ore. The recycling process includes collecting, sorting, cleaning, and melting the scrap to produce reusable copper. Specifications for Copper Scrap #1 Copper (Bare Bright) Description: Clean, unalloyed, uncoated copper wire. Purity: 99.9% Cu. Physical Characteristics: Bright and shiny, no insulation or tarnish. Common Uses: Electrical and plumbing applications. #1 Copper (Clove) Description: Clean, unalloyed copper tubing and bus bars. Purity: 99.9% Cu. Physical Characteristics: Free of paint, solder, and any attachments. Common Uses: Electrical and plumbing, high-grade manufacturing. #2 Copper Description: Unalloyed copper with minimal contamination. Purity: 96-99% Cu. Physical Characteristics: May have some paint, solder, or coatings. Common Uses: Low-grade electrical applications, plumbing. #3 Copper (Light Copper) Description: Copper with significant contamination or alloying. Purity: 80-96% Cu. Physical Characteristics: Includes thin gauge sheets, some corrosion. Common Uses: Industrial applications, lower-grade products. #4 Copper (Insulated Wire) Description: Copper wire with insulation. Purity: Varies. Physical Characteristics: Copper content varies with insulation type. Common Uses: Electrical applications where insulation is required. Copper Turnings Description: Small pieces of copper from machining processes. Purity: 94-99% Cu. Physical Characteristics: Fine and shavings, may have oil or moisture. Common Uses: Remelting and refining. Copper Granules Description: Copper pieces from recycled electrical cables. Purity: 98-99% Cu. Physical Characteristics: Granulated, often from mechanical recycling. Common Uses: Electrical manufacturing, foundries. Additional Notes Recycling Process: Involves collection, sorting, cleaning, and melting. Quality control is crucial to maintain purity levels. Market Value: Varies based on grade, market demand, and purity. Higher purity grades generally fetch higher prices. Environmental Impact: Recycling copper scrap significantly reduces the need for mining, thus conserving natural resources and reducing carbon footprint. This detailed specification provides a clear understanding of the different grades of copper scrap, helping in the appropriate identification and use of each type.

Granular urea, with a 46 percent nitrogen content, is a solid nitrogen fertilizer product. Produced from ammonia and carbon dioxide, it has the highest nitrogen content of any solid nitrogen fertilizer. It can be applied directly to the soil or mixed with other fertilizers like phosphate and potash to create a complete food mix for plants. This type of urea can be easily applied using conventional spreading equipment. Granular Urea Application: Raw material for other fertilizers production Manufacturing of melamine used in melamine-methanal resins (used for the synthesis of melamine through a chemical reaction involving urea and formaldehyde.) Formation of important resins (urea-formaldehyde resin) Use in reducing air pollution from diesel engines in cars, buses, and lorries
