1050 O Aluminum‌ Comparison with Other Tempers‌

‌H14 Temper (Semi-Hard)‌: Increased tensile strength but reduced plasticity‌.
‌Unannealed Temper‌: Strength is increased by cold deformation, but elongation is significantly reduced‌.

Comparison Temper	Description
H14 Temper (Semi-Hard)	Compared to 1050 H14 temper (semi-hard), 1050 O Aluminum offers higher plasticity and ductility, making it more suitable for deep drawing, spinning, bending, and other cold working processes. The H14 temper undergoes a certain degree of cold work hardening, which increases tensile strength but significantly reduces plasticity, making it more appropriate for applications that require moderate strength but lower forming complexity.
Unannealed Temper	1050 O Aluminum is in a fully annealed condition, offering excellent ductility and toughness, which is ideal for deep forming processes. In contrast, unannealed tempers (such as F temper or partially cold-worked states) rely on cold deformation to increase strength. However, this significantly lowers the material's elongation and forming adaptability, increasing the risk of cracks or fractures during processing. Thus, the O temper provides more stable and reliable performance in complex forming scenarios.

1050-O aluminum is a widely used high-purity alloy, valued for its ductility, corrosion resistance, and ease of fabrication. Although its mechanical strength is limited, its application spans various industries from construction to electrical engineering.
