Overview

SIST EN 2732:2005 is a European standard developed by CEN that specifies the technical requirements for the aerospace-grade magnesium alloy MG-C46001 in the T6 temper condition, produced through chill casting. This standard is part of the aerospace series focused on magnesium alloys, providing detailed guidance on chemical composition, heat treatment, mechanical properties, and quality assurance measures. It ensures material consistency, performance, and suitability for aerospace structural components.

The document is harmonized across multiple European countries, facilitating uniform aerospace manufacturing standards and ensuring compliance with rigorous safety and performance criteria for magnesium alloy components used in aircraft and aerospace applications.

Key Topics

• Material Specification: Defines the magnesium alloy MG-C46001 with specific chemical composition limits ensuring optimal strength and durability.
• Casting Method: Focuses on chill casting, a method providing fine-grained microstructure and superior mechanical properties.
• Heat Treatment Process: Details the T6 condition involving solution heat treatment, quenching, and aging to achieve desired mechanical characteristics.
• Mechanical Properties: Sets minimum values for proof stress (≥185 MPa), tensile strength (≥240 MPa), and elongation (≥2%) for aerospace applications.
• Quality Control: References EN 2076-3 for inspection of external/internal defects, batch uniformity, dimensional conformity, and product marking.
• Test Procedures: Specifies test piece preparation according to EN 2076-3, including separate casting or designated location sampling.
• Use Conditions: Clarifies application under ambient temperature with typical aerospace loading and stresses.
• Standard Compliance: Enforces adherence to EN 4500-2 for drafting and presentation rules and relates to EN 4258 for general aerospace metallic material standardization.

Applications

SIST EN 2732:2005 is primarily utilized in the aerospace industry for components requiring lightweight and high-strength metal alloys. Its typical applications include:

• Structural Aerospace Components: Airframe parts, brackets, housings, and fittings requiring high strength-to-weight ratio.
• Engine Components: Magnesium parts benefiting from good mechanical properties and heat resistance.
• Defense and Space Equipment: Lightweight frames and assemblies where corrosion resistance and performance under stress are critical.
• Precision Casting: Components where chill casting produces superior material consistency, reducing defects and enhancing reliability.
• Material Selection Guidance: Assists aerospace engineers and material scientists in selecting magnesium alloys conforming to strict standards for critical applications.
