Overview

EN 13920-12:2003 is a CEN European standard that specifies requirements for aluminium scrap in the form of turnings consisting of one single alloy (wrought or cast). It defines the physical characteristics, required chemical composition and minimum metal yield for turnings intended for recycling and remelting. Typical sources covered include scalpings, millings and borings from plates, extruded profiles and castings.

Key topics and requirements

• Scope and object: Turnings made from a single specified alloy (referenced to alloy specifications such as EN 573-3 for wrought alloys or EN 1706 for cast alloys).
• Ordering information: Contracts should include the standard number (EN 13920-12), scrap category, alloy designation or chemical composition, gross mass, delivery period and any deviations (e.g., particle size, foreign material). Origin and particle/surface details are recommended.
• Physical tolerances:
  • Magnetic iron: max 0.5 % (mass fraction)
  • Moisture and oil: max 5 % (mass fraction)
  • Fines passing 20 mesh (0.71 mm) after drying: max 3 % (mass fraction)
  • Scrap must be unoxidized and contain no other foreign material.
• Chemical composition: Turnings must match the chemical composition of the specified alloy in the contract.
• Metal yield: After drying and removal of free iron, metal yield shall be ≥ 90 %, determined per EN 13920-1.
• Compliance and testing: Sampling, classification, treatment of non-conformities and arbitration procedures follow EN 13920-1 and applicable terms/definitions in prEN 12258-3.

Applications and practical value

• Ensures consistent aluminium scrap quality for remelters and foundries, improving melt control and final alloy properties.
• Supports procurement and contract specification between scrap suppliers, traders and smelters by defining measurable acceptance criteria.
• Aids recyclers and recycling operators to optimize metal yield, reduce contamination and meet regulatory/quality requirements.
• Useful for quality control labs and inspectors conducting sampling and tests according to recognized European procedures.

Who should use this standard

• Aluminium scrap suppliers and brokers
• Secondary aluminium smelters and foundries
• Purchasing and quality assurance teams in aluminium manufacturing
• Recycling facility operators and process engineers
• Laboratories performing scrap analysis and metal-yield testing
