EN 573 and EN 755 Standards for 5754 Aluminium Pipes Explained

Aluminium pipes have become an essential material in industries ranging from construction to automotive and marine applications. Among the various aluminium alloys, 5754 aluminium pipes are widely recognized for their excellent corrosion resistance, moderate strength, and good formability. Ensuring that these pipes meet international standards is critical for performance, safety, and reliability. Two of the key standards governing aluminium pipes are EN 573 and EN 755. This article explains these standards in detail, focusing on 5754 aluminium pipes and their industrial applications.

Understanding 5754 Aluminium Pipes

5754 aluminium alloy belongs to the 5xxx series, where magnesium is the primary alloying element. This composition provides excellent corrosion resistance, especially in marine and industrial environments. Key features of 5754 aluminium pipes include:

  • High corrosion resistance

  • Good weldability and machinability

  • Moderate strength suitable for structural applications

  • Excellent formability for bending and shaping

5754 aluminium pipes are widely used in automotive panels, chemical processing equipment, marine structures, and architectural applications. To ensure reliability and performance, it is essential that these pipes comply with recognized international standards such as EN 573 and EN 755.

EN 573 Standard Overview

EN 573 is the European standard that defines the chemical composition and designation of wrought aluminium alloys. For 5754 aluminium pipes, EN 573 specifies:

  • Exact percentage ranges of magnesium, manganese, chromium, iron, silicon, copper, zinc, and other trace elements

  • Tolerances for chemical composition to ensure consistent material properties

  • Alloy designation system for proper identification and traceability

Compliance with EN 573 ensures that 5754 aluminium pipes have the required chemical composition to achieve optimal corrosion resistance, mechanical properties, and suitability for industrial applications. For example, the magnesium content in 5754 is typically in the range of 2.6–3.6%, providing strength while maintaining excellent corrosion resistance.

Key Benefits of EN 573 Compliance

  • Consistent quality and performance across batches

  • Reliable corrosion resistance in marine and industrial environments

  • Traceable material specification for regulatory and safety requirements

EN 755 Standard Overview

While EN 573 focuses on chemical composition, EN 755 defines the mechanical and dimensional requirements for aluminium and aluminium alloy extruded profiles, including pipes. For 5754 aluminium pipes, EN 755 covers:

  • Tolerances for outer diameter, wall thickness, and length

  • Mechanical properties, including yield strength, tensile strength, and elongation

  • Surface finish and defects criteria for aesthetic and functional requirements

  • Testing methods to verify compliance with specified tolerances

EN 755 ensures that 5754 aluminium pipes not only have the correct chemical composition but also meet mechanical, dimensional, and surface quality requirements. Compliance with this standard guarantees pipes suitable for critical applications, such as pressure vessels, structural supports, and transportation systems.

Key Benefits of EN 755 Compliance

  • Assurance of mechanical strength and performance

  • Consistent dimensions for assembly and installation

  • High-quality surface finish suitable for visible or functional applications

  • Reliable testing methods for quality control

Differences Between EN 573 and EN 755

Although both EN 573 and EN 755 apply to 5754 aluminium pipes, they focus on different aspects:

  • EN 573: Specifies chemical composition and alloy designation

  • EN 755: Defines mechanical properties, dimensional tolerances, and surface quality

Using both standards together ensures that 5754 aluminium pipes meet both chemical and mechanical performance requirements, providing a complete quality framework for manufacturers and end-users.

Applications of 5754 Aluminium Pipes Compliant with EN 573 and EN 755

5754 aluminium pipes that comply with EN 573 and EN 755 standards are widely used across various industries:

  • Automotive Industry: Lightweight structural components, exhaust systems, and fuel lines

  • Marine Applications: Boat fittings, marine piping, and corrosion-resistant structural elements

  • Construction Industry: Architectural frameworks, handrails, and façades

  • Chemical and Food Processing: Corrosion-resistant piping and storage systems

  • HVAC Systems: Air conditioning ducts and heat exchanger components

Compliance with EN 573 and EN 755 ensures that these pipes deliver consistent performance in demanding environments, enhancing safety, durability, and operational efficiency.

Quality Assurance and Testing

To verify compliance with EN 573 and EN 755, manufacturers conduct rigorous testing, including:

  • Chemical Analysis: Verifying magnesium and alloying elements content

  • Mechanical Testing: Assessing yield strength, tensile strength, and elongation

  • Dimensional Inspection: Measuring pipe diameter, wall thickness, and length

  • Surface Quality Check: Detecting defects, scratches, or other imperfections

Adhering to these standards ensures that 5754 aluminium pipes perform reliably under industrial conditions and meet customer expectations.
