EN 2088:2005

Overview

EN 2088:2005 is a European standard published by the Comité Européen de Normalisation (CEN) that specifies the technical requirements for aluminium alloy AL-P2014A in clad sheet and strip forms. These materials are tailored for aerospace applications, specifically covering thicknesses ranging from 0.4 mm to 6 mm. The standard applies to aluminium alloy in the T4 or T42 temper conditions, ensuring suitability for high-performance aerospace manufacturing.

This standard is part of the broader aerospace series standards designed to regulate metallic materials for aerospace use, providing uniformity in product performance, quality, and testing procedures across the European aerospace sector.

Key Topics

• Material Specification: Defines aluminium alloy AL-P2014A clad sheet and strip, outlining the specific chemical composition limits to guarantee mechanical performance and corrosion resistance.

• Temper Conditions: Covers T4 and T42 temper states. T4 includes solution heat-treated and naturally aged conditions, while T42 encompasses a similar heat treatment followed by controlled artificial aging, enhancing mechanical properties for aerospace needs.

• Dimensional Range: Thickness between 0.4 mm and 6 mm, accommodating various aerospace component design requirements.

• Cladding: Specifies the use of aluminium cladding to protect against corrosion. The cladding material is typically high-purity aluminium (AL-P1050A or AL-P1145), with defined chemical limits for elements such as silicon, iron, copper, and others.

• Mechanical Properties: Establishes minimum mechanical criteria like proof stress, tensile strength, and elongation percentages to assure durability and structural integrity under aerospace operating conditions.

• Testing and Inspection: Refers to established aerospace testing standards (such as EN 4400-2) for dimensional, chemical, mechanical, and surface inspections to maintain batch uniformity and inspection reliability.

Applications

EN 2088:2005 aluminium alloy AL-P2014A clad sheets and strips are critical materials used extensively within aerospace manufacturing, particularly for:

• Aircraft structural components requiring high strength-to-weight ratios.
• Panels and shells where corrosion resistance and durability are vital.
• High-performance aerospace assemblies where consistent material properties guarantee safety and compliance.
• Manufacturing processes involving rolling and forming operations that benefit from the defined temper and clad characteristics.

Compliance with EN 2088:2005 ensures aerospace manufacturers achieve consistent, reliable aluminium materials optimized for demanding flight environments, contributing to overall aircraft safety, weight efficiency, and lifecycle longevity.
