Overview

EN 1676:2020 - "Aluminium and aluminium alloys - Alloyed ingots for remelting - Specifications" is a European standard published by CEN that defines requirements for alloyed aluminium ingots intended for remelting. The standard covers classification and designation systems, production and manufacturing conditions, chemical composition limits, quality control, marking, packaging and delivery documentation for remelt ingots used in the aluminium value chain.

This revision (2020) supersedes EN 1676:2010 and includes updates to alloy listings and composition limits.

Key topics and requirements

• Scope and designations: Specifies how alloyed ingots for remelting are classified and designated (numerical and chemical-symbol systems referenced to EN 1780 series).
• Chemical composition: Lists allowable element concentrations for many common casting and remelt alloys in Table 1. The standard requires compliance with those limits unless purchaser and supplier agree otherwise.
• Production & manufacturing: Allows producer discretion for processes unless the order document states otherwise; suppliers must notify purchasers of changes that could affect quality.
• Quality control & testing: Requires supplier responsibility for inspection and tests before shipment. Chemical analysis methods and sampling are referenced (EN 14242 for ICP-OES analysis; EN 14361 for sampling).
• Freedom from defects & form: Sets expectations for acceptable product form and defect tolerances for ingots.
• Ordering information: Defines mandatory order details (alloy designation, product form, quantity, certificate requirements, and any special conditions).
• Marking, packaging & delivery documents: Specifies identification marks, packaging practices and documentation to accompany shipments.
• Inspection & complaints: Procedures for product inspection, testing, inspection documents and complaint handling are included.

Key changes in the 2020 revision include deletion and addition of certain alloys in Table 1 and a reduction of the maximum permissible lead content.

Applications and users

EN 1676:2020 is directly relevant to:

• Foundries, remelters and aluminium recyclers managing ingot feedstock
• Primary and secondary aluminium producers supplying alloyed ingots
• Purchasing, quality and metallurgical engineers specifying feedstock for casting or extrusion
• Product designers and specifications writers ensuring material traceability
• Certification bodies and testing laboratories performing chemical analysis

Use cases include procurement of remelt ingots, material compliance checks, supplier contracts, and quality control programs in aluminium casting and recycling operations.
