Product Overview
The 2000 series aluminum alloys (Al-Cu-Mg, "Duralumin") are heat-treatable, high-strength materials, second only to the 7000 series in tensile strength. They are widely known as aviation-grade aluminum for critical structural applications.
Core Composition & Grades
- Main alloying elements: Copper (Cu: 3.8-5.0%) + Magnesium (Mg: 1.2-1.8%), plus Mn/Ti for grain control
- Common grades:
- 2024 (Al-4.4Cu-1.5Mg-0.6Mn): The most popular high-strength grade
- 2A12 (LY12): Chinese equivalent of 2024
- 2017 (2A11): Medium-strength, good formability
- 2011: Free-cutting grade with Pb/Bi for precision machining
- 2219: High-temperature resistant, for aerospace fuel tanks
Key Properties
- High strength: Tensile strength 420-480 MPa (T3/T4), comparable to some steels
- Heat-treatable: Strength enhanced via solution treatment + aging (T3/T4/T6)
- Good machinability: Excellent for CNC, threading, and precision parts (especially 2011)
- Moderate corrosion resistance: Prone to intergranular corrosion; requires anodizing, cladding, or painting
- Limited weldability: Susceptible to cracking; riveting/bolting preferred
Typical mechanical properties (2024-T3):
Tensile strength: 470 MPa
Yield strength: 325 MPa
Elongation: 10%
Hardness: 120 HB
Tensile strength: 470 MPa
Yield strength: 325 MPa
Elongation: 10%
Hardness: 120 HB
Available Forms & Sizes
- Bar/Rod: Round, square, flat, hexagonal
- Diameter: 5-500 mm (customizable)
- Length: 1-6 m (cut-to-length available)
- Surface: Mill finish, polished, anodized, or coated
Main Applications
- Aerospace: Aircraft fuselage, wings, ribs, spars, rivets, and landing gear components
- Automotive: High-performance engine parts, transmission components, and racing car structures
- Industrial: High-strength fasteners, precision machinery parts, and structural components requiring light weight and high strength
Standards & Specifications
- International: ASTM B211, AMS 4120, EN 573-3, JIS H4100
- Chinese: GB/T 3191, GB/T 3880.2
Advantages & Disadvantages
Advantages
- Ultra-high strength-to-weight ratio
- Excellent fatigue resistance
- Superior machinability
- Mature production and global supply
Disadvantages
- Higher cost than 1000/6000 series
- Poor corrosion resistance without surface treatment
- Not ideal for welding
Summary
2000 series aluminum bars/rods are the premium choice for high-strength, lightweight structural applications, especially in aerospace and defense. Their combination of strength, machinability, and reliability makes them irreplaceable in critical engineering scenarios.
