2024 Al-Cu-Mg Strengthened Duralumin Rod

The 2024 alloy is a heat-treatable, high-strength aluminum alloy (a 2xxx-series aerospace-grade aluminum). It derives its strength from the formation of strengthening phases involving copper (Cu) and magnesium (Mg). It features high tensile strength, excellent fatigue resistance, and good machinability. Common tempers include T3 and T351 (the latter involves pre-stretching for stress relief and is the preferred choice for precision machining).

The 2024 alloy is a heat-treatable, high-strength aluminum alloy (a 2xxx-series aerospace-grade "duralumin"). It derives its strength from the formation of strengthening phases involving copper (Cu) and magnesium (Mg). It offers high strength, excellent fatigue resistance, and good machinability. Its drawbacks include relatively poor corrosion resistance and poor weldability (it is not suitable for fusion welding). Common tempers include T3 and T351 (the latter involves pre-stretching for stress relief, making it the preferred choice for precision machining). Its density is 2.78 g/cm³.

Key comparisons: Its strength is second only to 7075; it exhibits superior toughness and fatigue resistance compared to 7075; however, its corrosion resistance is inferior to that of all 6xxx-series alloys and 5083 aluminum.

Brinell Hardness HB	120~130 HB

Note: The T3 temper offers performance similar to T351, but it retains high residual stress, making it prone to deformation during precision machining. In contrast, the T351 temper undergoes a stretching process for stress relief, providing superior stability during CNC machining.

Applications

1. Aerospace: Aircraft structural components, wing connectors, load-bearing airframe frames, and blanks for aerospace rivets.

2. High-end Machinery: Components subject to high fatigue, heavy-duty precision fixtures, and blanks for high-strength bolts.

3. Transportation Equipment: Truck wheel hubs, structural components for racing vehicles, and aircraft parts.

4. Defense/Military: Various load-bearing components requiring high toughness and fatigue resistance.

5. General Precision Machining: Structural parts that require a combination of high toughness and good machinability.

Precautions: Not suitable for fusion welding; exhibits poor corrosion resistance in its bare state (requires protective treatment if exposed to humid or salt-spray environments); not suitable for long-term use in high-temperature conditions.

Payment Methods

Flexible payment terms available: T/T and L/C. For new clients, 30% advance payment for production, balance against copy of B/L. L/C is acceptable for large & regular orders to secure both parties.

Warehousing Management

Before each batch of steel leaves the factory, a complete process inspection is strictly carried out. From chemical composition, mechanical properties to dimensional tolerance and surface quality, each item is carefully checked to ensure compliance with national standards and export regulations. At the same time, the quantity, packaging and rust prevention treatment are also verified. An original factory warranty certificate is attached, guaranteeing the quality. Before shipment, inspection photos are provided. Any non-compliant items will not be released, and the quality is fully controllable throughout the process. This ensures your overseas purchasing is safe and worry-free.

All items are visually inspected before delivery. No cracks, deformation, rust, scratches or cutting marks are allowed; edges must be smooth. Only visually sound products will be shipped.

Thickness, width, length, wall thickness, outer diameter have been measured. Straightness, curvature, torsion, diagonal tolerance all meet the corresponding tolerance requirements.

Quality inspection includes: mechanical property tests (yield strength, tensile strength), elongation rate, impact energy, hardness testing, chemical composition testing, process performance testing, etc.

Inspection according to packaging requirements: secure binding, moisture-proof film, rust-proof paper, export fumigation/fumigation-free wooden crates, shipping marks, gross weight, net weight, etc.

We will provide full reception services to support the customers' on-site inspection of the goods.
