3003 H14 Aluminum Coil
What Does "3003 H14" Mean?
3003：An aluminum-manganese (Al-Mn) alloy containing approximately 1.0–1.5% manganese, offering higher strength than 1100 aluminum while retaining excellent corrosion resistance.
H14：A temper designation indicating the material has been strain hardened and partially annealed to achieve a half-hard condition, providing a good balance between strength and formability.
Key Features
