Conforming to ASTM B210, ASTM B491, and EN 573-3 standards, 3003 aluminum round tubing features a manganese-enhanced alloy formulation optimized for superior formability and corrosion resistance:
Primary Elements:
Manganese (Mn): 1.0-1.5% (increases strength without compromising ductility)
Magnesium (Mg): ≤0.10% (trace amounts for processing enhancement)
Base Material:
Aluminum (Al): ≥97.8% (balance)
Impurity Limits:
Iron (Fe): ≤0.7%
Silicon (Si): ≤0.6%
Copper (Cu): 0.05-0.20%
Zinc (Zn): ≤0.10%
Supplied in strain-hardened tempers including H14 (¼ hard), H18 (½ hard), and O (annealed) per ASTM B210 specifications. Certified to MIL-T-5062B for marine applications and NSF/ANSI 61 for potable water systems. Third-party verification confirms consistent intermetallic phase distribution critical for uniform corrosion resistance.
