General Information

Abstract

This European Standard specifies the requirements for grades of master alloys produced by melting and intended for addition to a melt to adjust composition and/or to control impurities and/or to control the as-cast structure. It specifies the classification and designation applicable to these grades, the conditions in which they are produced, their properties and the marks by which they are identified.

Overview

EN 575:1995 - Aluminium and aluminium alloys: Master alloys produced by melting - Specifications is a European (CEN) standard that defines requirements for master alloys made by melting and intended for addition to aluminium melts. The standard covers classification and designation of master-alloy grades, the production conditions under which they are made, their required properties and the marking/identification used for traceability. (Referenced in some countries as SIST EN 575:1998; ICS 77.120.10.)

Key topics and requirements

  • Scope and purpose: Specifies master alloys produced by melting used to adjust melt composition, control impurities, and influence the as-cast structure.
  • Classification & designation: Defines how master-alloy grades are named and categorized so purchasers and producers can unambiguously identify product types.
  • Production conditions: Sets expectations for manufacturing processes and environmental/handling aspects specific to master alloys produced by melting.
  • Properties and quality: Describes required physical and chemical characteristics (composition control, impurity limits and functional performance criteria) that ensure consistent behavior when alloying melts.
  • Marking and identification: Requires product marking and documentation for traceability, quality assurance and correct use in melting operations.
  • Inspection and conformity: Implies the need for testing, inspection and acceptance criteria so suppliers and users can verify compliance.

Note: EN 575 provides specification-level requirements; it does not prescribe detailed processing parameters for downstream casting or heat treatment.

Applications and who uses it

  • Foundries and aluminium casthouses: to select appropriate master alloys for alloying and impurity control during melting and casting.
  • Aluminium producers and alloy manufacturers: for producing, certifying and labeling master-alloy batches that meet European specification requirements.
  • Metallurgists and materials engineers: to ensure composition adjustments and grain/structure control meet product design and performance targets.
  • Procurement and quality managers: to define purchase specifications, perform supplier assessments and maintain traceability of alloy additions.
  • Laboratories and testing houses: for establishing acceptance tests and verifying conformity of supplied master alloys.

Related standards

  • Other CEN/EN standards covering aluminium alloy compositions, testing methods and casting practices are typically used alongside EN 575 to define complete material qualification and production workflows.
  • National adoptions (e.g., SIST EN 575) reflect the same technical requirements within local standards organizations.
