SIST EN 2693:2005

Overview

SIST EN 2693:2005 is a European Standard developed by the European Committee for Standardization (CEN) specifically for aerospace applications. This document specifies the technical requirements for aluminium alloy AL-P5086-H111 sheet and strip with thicknesses ranging from 0.3 mm to 6 mm. The standard aims to ensure high-quality material performance, reliability, and safety in the aerospace industry. SIST EN 2693:2005 replaces the earlier EN 2693:1993 and aligns with aerospace manufacturing standards to provide uniformity across member countries.

Key Topics

• Material Designation: Aluminium alloy AL-P5086-H111, designed for aerospace-grade sheet and strip products.
• Thickness Range: Applicable for sheets and strips with thickness 0.3 mm ≤ a ≤ 6 mm.
• Chemical Composition: Specifies precise element limits including Si, Fe, Cu, Mn, Mg, Cr, Zn, Ti, and Al ensuring optimal mechanical and corrosion-resistant properties.
• Mechanical Properties: Requires minimum proof stress of 100 MPa and tensile strength of at least 240 MPa for various thickness ranges; elongation percentages are also defined.
• Delivery Condition: Material supplied in H111 heat treatment state, to maintain consistent strength and ductility.
• Production Method: Rolled sheet and strip manufactured under strict aerospace standards.
• Test Procedures: Testing samples and pieces follow the specifications of EN 4400-2, including tensile, bending, and corrosion resistance tests.
• Application-Specific Quality Controls: Emphasis on dimensional and marking inspection, external defect checks, and product qualification aligned with aerospace requirements.

Applications

SIST EN 2693:2005 standard aluminum alloy sheets and strips are specifically designed for use in aerospace manufacturing and assembly, including:

• Aircraft structural components where high strength-to-weight ratio and corrosion resistance are essential.
• Aerospace panels, fuselage linings, and secondary structural elements.
• Components requiring precise dimensional control and mechanical reliability under operational stresses.
• Applications demanding compatibility with aerospace heat treatments and surface treatments to maintain integrity and durability.

The alloy AL-P5086-H111 is ideal for lightweight aerospace engineering, providing excellent formability, weldability, and resistance to environmental degradation.
