Overview

EN 13920-13:2003 (CEN) covers requirements for aluminium scrap in the form of mixed turnings consisting of two or more alloys. The standard defines the characteristics, required chemical composition (after magnetic sorting and melting), and expected metal yield for this scrap category. Typical examples include scalpings, millings and borings from plates, extruded profiles and castings intended for recycling and remelting.

Key topics and requirements

• Scope and classification: Applies specifically to mixed turnings made of two or more aluminium alloys; part of the EN 13920 scrap series for aluminium and aluminium alloys.
• Condition of material: Scrap must be unoxidized and free of other foreign materials.
• Notification requirements: Suppliers must notify purchasers if the scrap contains alloys of the 7xxx series or any other characteristics that deviate from the standard. Agreement is required prior to shipment.
• Tolerances on delivered mass:
  • Magnetic iron: ≤ 0.5% (mass fraction)
  • Moisture and oil: ≤ 5% (mass fraction)
  • Fines passing a 20 mesh sieve (0.71 mm) after drying: ≤ 3% (mass fraction)
• Chemical composition: A defined composition applies after magnetic sorting and melting; the standard references a tabulated composition (Table 1) that purchasers and suppliers use to verify conformity.
• Metal yield: The metal yield (after drying and removal of free iron) shall be ≥ 90%, determined per EN 13920-1.
• Sampling, testing and non-conformities: Classification, sampling, test methods, treatment of non-conformities and arbitration follow EN 13920-1.

Applications and who uses it

EN 13920-13 is used by:

• Aluminium recyclers and smelters - to verify incoming mixed-turnings feedstock and ensure predictable melt chemistry and yield.
• Scrap processors and brokers - to classify, price and sell consignments consistently across European markets.
• Purchasing and quality teams in metal-producing companies - to specify acceptable scrap quality and reduce disputes.
• Environmental and operations managers - for process planning, inventory control and optimizing remelting efficiency.

Practical benefits include improved material traceability, consistent alloying behavior in remelting, predictable metal recovery rates, and clearer contractual terms between buyer and supplier.
