Introduction to 3003 H14 Aluminum
3003 aluminum is alloyed with approximately 1.20% manganese, which provides higher strength than commercially pure aluminum in the 1100 series. This alloy offers excellent machinability, good weldability, and strong corrosion resistance. It is commonly used for drawing, forming, spinning, fuel tanks, and general sheet metal fabrication where moderate strength and reliable weldability are required. The H14 temper indicates that the 3003 aluminum has been strain hardened and partially annealed. At GNEE, 3003 H14 aluminum is supplied to meet a wide range of industrial and fabrication needs.
Alternative designations
Aluminum 3003-H14, AA3003-H14, Al3003-H14
Standards and specifications
GNEE 3003 H14 aluminum conforms to ASTM B209, QQ-A-250/2, AMS 4006, and AMS 4008 standards.
Mechanical properties
Minimum 90° cold bend radius (for 0.064 in thickness): 0
Note: The values listed are average figures and are considered representative of typical 3003 H14 aluminum performance.
Applications
3003 H14 aluminum is widely used in stampings, spun and deep-drawn parts, cookware, chemical equipment, builder's hardware, storage tanks, truck and trailer components, mailboxes, cabinets, fan blades, awnings, siding, kitchen equipment, decorative trim, architectural applications, and signage. When higher strength is required, 5052-H32 aluminum may be considered as an alternative.
Machinability and weldability
3003 H14 aluminum has a machinability rating of approximately 97% when compared to 2011 aluminum at 100%. It can be easily welded using all common aluminum welding methods.
Heat treatment
3003 H14 aluminum is not heat-treatable; its strength is achieved through strain hardening rather than heat treatment.

Temper of 3003 H14 Aluminum
The H14 designation in 3003 aluminum refers to its temper, indicating that the material has been strain hardened and partially annealed. This condition gives the alloy excellent formability, making it easy to shape and fabricate. A common variation is the 3003 H14 aluminum diamond sheet, which offers the same material properties while featuring a raised pattern that provides slip resistance and an attractive appearance. Despite its light weight, it maintains good strength.
When cold bending 3003 H14 aluminum, it is recommended that the working temperature be around 30°F to ensure optimal forming performance. This alloy is widely used in applications such as cookware, storage tanks, mailboxes, fan blades, kitchen equipment, architectural components, and builder's hardware. It is also commonly applied in truck trailers and beds, catwalks, flooring, decorative trim, and walkways.
3003 H14 aluminum has a machinability rating of approximately 97% when compared to 2011 aluminum at 100%. It can be readily welded using standard aluminum welding techniques. Heat treatment is not applicable for strengthening this alloy.
