Chemical Composition of 1050 Aluminum Tube (Mass Percentage, %)

1050 belongs to industrial pure aluminum (purity ≥99.5%). Its typical composition is as follows:

Element Aluminum Iron Silicon Copper Manganese Zinc Other Impurities (Each) Other Impurities (Total)
(Al)** (Fe)** (Si)** (Cu)** (Mn)** (Zn)**

Content ≥99.50 ≤0.40 ≤0.25 ≤0.05 ≤0.05 ≤0.07 ≤0.03 ≤0.15

Note: Specific compositions may vary slightly depending on standards (e.g., ASTM, GB/T 3190), but aluminum content remains ≥99.5%.

Mechanical Properties of 1050 Aluminum Tube

Mechanical properties are significantly influenced by material states (annealed, cold-worked, etc.). Common states and properties are listed below:

State Tensile Strength Yield Strength Elongation Hardness
(MPa) (MPa) (%, ≥) (HB)

Annealed (O) 60~95 15~35 25~35 20~30

Half-Hard (H14) 110~140 95~125 6~12 35~45

Full-Hard (H18) 150~180 140~170 2~5 50~60

Notes:

State Description

O State: Annealed condition, excellent plasticity for forming.

H14/H18: Cold-worked hardened states with increased strength and reduced plasticity.

Testing Standards: ASTM B491 (extruded round tubes) or relevant national standards.

Actual properties may vary slightly due to production processes, wall thickness, etc.
