3003 aluminum is alloyed with 1.20% manganese, which increases the strength of 3003 over commercially pure aluminum (1100 series). 3003 has excellent workability, weldability, and good corrosion resistance. It is used for drawing, forming, spinning, fuel tanks, sheet metal works, and other applications that require moderate strength for an aluminum with good weldability. H14 designates the temper and means that 3003 has been strain hardened and partially annealed. In this condition, 3003 can be easily formed. Embossing or debossing 3003 in this temper should not strain or crack the aluminum. 3003 Aluminum tread plate, often referred to as diamond plate, has the same properties of 3003-H14, while excellent at resisting corrosion, and strong for lightweight aluminum applications. The diamond trend pattern is slip-resistant and cosmetically appealing.

3003-H14 conforms to ASTM BB209, QQ-A-250/2, AMS 4006, AMS 4008.


General Information about 3003:


3003 is widely used for stampings, spun and drawn parts and products, cooking utensils, chemical equipment, builders hardware, storage tanks, truck and trailer components, mailboxes, cabinets, fan blades, awnings, siding, kitchen equipment, decorative trim, architectural uses, signage applications, etc. Where greater strength is required, consider 5052-H32. 3003 Aluminum Tread plate is widely used for truck beds and trailers, walkways and catwalks, flooring, wall panels, tool boxes, decorative trim, architectural uses, etc.


3003 has a machinability rating of 97% when compared to 2011 at 100% and can be welded using all the most common welding techniques.

HEAT TREATING - Forging, Normalizing, and Annealing:

3003 is not heat treatable.
