Specification for Aluminum Scrap 1. Scope This specification defines the quality and requirements for aluminum scrap intended for recycling and manufacturing. It ensures consistency, quality, and suitability for various applications. 2. Material Requirements 2.1. Composition Aluminum Content: Minimum 90% by weight. Contaminants: Maximum 2% by weight of non-aluminum metals (e.g., steel, copper). Maximum 1% by weight of non-metallic materials (e.g., plastic, rubber). Moisture content should not exceed 2% by weight. 2.2. Form and Condition Types: Can include profiles, sheets, turnings, wire, and castings. Size: Must be manageable for handling and processing, typically not exceeding 1 meter in any dimension. Cleanliness: Free from excessive oil, grease, and other foreign substances. 3. Packaging and Labeling Packaging: Scrap should be securely packaged or bundled to prevent scattering and contamination during transport. Packaging materials should not contaminate the scrap. Labeling: Each package should be clearly labeled with: Supplier name and address. Net weight. Scrap grade and type. 4. Inspection and Testing Visual Inspection: Performed to check for visible contaminants, appropriate size, and cleanliness. Chemical Analysis: Periodic testing to verify aluminum content and contaminant levels. Moisture Test: Conducted to ensure moisture content compliance. 5. Documentation Certificate of Analysis (CoA): Provided with each shipment, detailing the chemical composition and confirming compliance with this specification. Bill of Lading: Including details of the shipment, weight, and scrap grade. 6. Compliance and Rejection Compliance: All supplied scrap must meet the requirements outlined in this specification. Rejection: Material not meeting these requirements will be subject to rejection and return at the supplier's expense. 7. Safety and Handling Handling: Appropriate safety measures should be taken to prevent injury or contamination during handling and transportation. Personal Protective Equipment (PPE): Workers must use suitable PPE, including gloves and eye protection. 8. Environmental and Regulatory Considerations Compliance: Must comply with all relevant local, national, and international regulations regarding waste and recycling materials. Environmental Impact: Suppliers are encouraged to follow environmentally friendly practices in the collection and processing of aluminum scrap.

Copper Wire Scrap Specification 1. Product Description Copper wire scrap refers to discarded copper wire materials that are collected and recycled for reuse. These scraps are typically sourced from electrical wiring, cables, and other copper-based components. The high conductivity and malleability of copper make it a valuable material in various industries, including electrical, construction, and manufacturing. 2. Chemical Composition The copper wire scrap must meet the following chemical composition standards: Copper (Cu): 99.9% minimum Impurities: 0.1% maximum 3. Physical Characteristics Appearance: Clean, uncoated, and untinned copper wire Color: Bright or bare copper color Wire Diameter: Typically ranges from 1 mm to 3 mm Length: Varies, can be in coils, bundles, or chopped 4. Quality Standards ISRI Code: Should conform to ISRI (Institute of Scrap Recycling Industries) specifications for copper wire scrap. Cleanliness: Free from dirt, plastic, rubber, other metals, and non-metallic materials. Radiation: Free from any radioactive contamination. Corrosion: Free from excessive oxidation or corrosion. 5. Packaging Form: Bundles, bales, or coils Weight: Typically packed in 20-25 kg bundles or as per customer requirements Securing: Strapped with steel or plastic bands to prevent spillage during transportation Labeling: Each package should be labeled with the following information: Grade of copper Net weight Supplier's name Batch number Date of packaging

2. Specifications: Material: Copper wire with various degrees of insulation or bare copper. Types: Bare Bright Copper Wire: Clean, uncoated, unalloyed copper wire that is free of any impurities. Insulated Copper Wire: Copper wire with various types of insulation, including PVC (Polyvinyl Chloride), Teflon, rubber, etc. Copper Content: Generally ranges from 95% to 99.9% pure copper, depending on the grade. Gauge/Thickness: Typically ranges from very thin wires (e.g., 18 AWG) to thicker cables (e.g., 2/0 AWG or higher). Condition: Clean: Free from any contaminants or corrosion, suitable for direct recycling. Tinned: Copper wire coated with a thin layer of tin to enhance solderability. Burnt: Copper wire that has undergone burning or oxidation, affecting its physical properties and purity. Packaging: Usually bundled in coils, spools, or loose in containers depending on quantity and logistics requirements. Application: Used as a raw material in the production of new copper products such as electrical wiring, motors, transformers, and various electronic components. Environmental Considerations: Recycling scrap copper wire reduces the need for mining new copper ore, which helps conserve natural resources and reduces energy consumption and greenhouse gas emissions associated with copper production. 3. Quality Standards: Compliance with local and international standards for metal recycling and copper content purity. Adherence to environmental regulations regarding the handling and disposal of scrap materials. Quality control measures to ensure the absence of hazardous materials and proper sorting for optimal recycling efficiency.
