2A11 Aluminum Rods: Cost-Effective Medium-Strength Solution for General Industrial Precision Parts

2A11 Aluminum Rods: Cost-Effective Medium-Strength Solution for General Industrial Precision Parts

In general industrial manufacturing—where components need reliable strength, easy processability and budget-friendly pricing—high-end aerospace-grade aluminum rods often lead to unnecessary cost waste. This is where 2A11 aluminum rods shine: as a classic 2000-series Al-Cu-Mg alloy, it balances medium strength and cost efficiency, becoming the go-to choice for precision parts in agricultural machinery, general equipment and hardware tooling sectors.

The core advantage of 2A11 lies in its cost-performance ratio, supported by optimized alloy composition and heat treatment. Composed of 3.8-4.8% copper, 0.4-0.8% magnesium and trace manganese for structural stability, it delivers solid mechanical properties after T3/T4 tempering. In T4 temper, it achieves tensile strength up to 370MPa and yield strength ≥210MPa—meeting the needs of most low-to-medium stress industrial scenarios, while its price is 20-30% lower than aerospace-grade 2A12. Fully compliant with GB/T 3196 standards, it ensures consistent quality for batch production without overspending.

Its processability is tailored for general industrial manufacturing: excellent machinability enables tight dimensional tolerances (±0.03mm) for complex parts like gear shafts and connecting rods, while TIG welding with matching fillers retains 65-70% joint strength—suitable for on-site assembly. With a density of 2.8g/cm³, it balances structural rigidity and lightweight design, reducing the overall weight of equipment. A key note: its corrosion resistance is moderate; chemical conversion coating or spray painting is recommended for outdoor or humid working environments.

Target application scenarios focus on cost-sensitive, medium-stress industrial fields: Agricultural machinery (harvester transmission components, seeder brackets)—withstanding long-term vibration and field wear; General mechanical equipment (pump valve cores, reducer shafts)—ensuring stable operation under continuous load; Hardware tooling (precision mold frames, fixture bases)—supporting repeated clamping without deformation; Light industrial products (furniture hardware connectors, elevator guide rails)—combining strength and aesthetic finish after surface treatment.

Our supply chain is optimized for general industrial batch demand: 3500 tons of 2A11 aluminum rods in stock (T3/T4 tempers), covering diameters 5-180mm and lengths up to 6m (round/square profiles available). Every batch undergoes ultrasonic flaw detection (level II) and certified mechanical test reports, ensuring no internal defects affect part performance. We offer value-added services including precision cutting (±0.05mm tolerance), sandblasting and spray painting, with standard specifications shipping in 3-5 days.
