Aluminium 2024 is a prominent member of the aluminium-copper alloy family, celebrated for its exceptional strength-to-weight ratio and excellent fatigue resistance. This alloy, known by various names in different international standards, finds extensive application across industries where high strength and reliability are paramount.
- Aluminium 2024 (International Naming):
Internationally, this alloy is commonly referred to as “Aluminium 2024.” Its composition consists of approximately 4.5% copper, 1.5% magnesium, and a trace of manganese. These alloying elements contribute to the remarkable mechanical properties that make Aluminium 2024 highly sought after for critical applications.
- Aluminum 2024 (American English):
In the United States, the American Society for Testing and Materials (ASTM) designates this alloy as “Aluminum 2024.” Its unique combination of strength and fatigue resistance makes it a favored choice for aerospace components, aircraft structures, and other high-stress applications. The ASTM classification ensures standardization and quality in its manufacturing and use.
- Aluminium 2024 (European Standard):
In Europe, the Aluminium Association identifies this alloy as “Aluminium 2024.” Its widespread utilization in the aerospace industry is due to its capacity to withstand heavy loads while maintaining its structural integrity. The European standardization ensures consistency and compatibility in various engineering and manufacturing processes.
- Aluminium AlCu4Mg1 (EN Standard):
Following the EN standard, Aluminium 2024 is denoted as “Aluminium AlCu4Mg1.” This alphanumeric code reveals its elemental composition – aluminum (Al), copper (Cu), magnesium (Mg), and trace elements. The “4” and “1” represent the respective percentages of copper and magnesium. This standardized naming system aids in accurate material identification and specification compliance.
- 2024-T3 (Temper Designation):
In the temper designation system, “2024-T3” indicates the specific heat treatment applied to Aluminium 2024. “T3” signifies that the material has undergone solution heat treatment, followed by cold working. This temper provides excellent mechanical properties and makes the alloy suitable for applications requiring both strength and formability.
- Duralumin (Historical Term):
Duralumin, an older and less specific term, historically referred to a group of aluminium alloys that included Aluminium 2024. Although the term “duralumin” has largely fallen out of use, it represents the pioneering era of aluminium alloy development and its significance in early aviation and engineering.
- A-U4G (Russian Standard):
In the Russian standard, Aluminium 2024 is represented as “A-U4G.” The “A” signifies aluminum, followed by “U4G,” which represents the Russian abbreviation for copper (У – медь) and magnesium (Mг – магний). This nomenclature aligns with the standardized naming conventions of the country.
Aluminium 2024 is celebrated for its remarkable strength, fatigue resistance, and versatility, making it a staple in industries such as aerospace, automotive, and structural engineering. Its use in critical components, where reliability is non-negotiable, underscores its importance in modern technology and infrastructure. Whether it’s soaring through the skies or supporting intricate structures, Aluminium 2024 stands as a testament to the ingenuity of material science and engineering.
