Standards
ASTM-B-209 QQ-A-250/2

Principal Design Features
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 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.

Applications
3003-H14 is widely used for stampings, spun and drawn parts and products, cooking utensils, chemical equipment, builder’s hardware, storage tanks, truck and trailer components, mail boxes, cabinets, fan blades, awnings, siding, kitchen equipment, decorative trim, architectural uses, signage applications, etc. Where greater strength is required, consider 5052-H32. 3003-H224 is a designation for a variety of tread designs for tread plate, this product is often used for walk ways, bump zones trailer decks etc.

Machinability
Machinability for 3003-H14 is considered good.

Forming
Good.

Welding
3003-H14 is readily welded using common welding techniques.

Heat Treatment
3003-H14 is not heat treatable.

Principal Design Features
Magnesium is the primary alloying agent in the 5052 series and is one of the most effective and widely used alloying elements for aluminum. Alloys in this series possess moderate to high strength characteristics, as well as good weldablilityand resistance to corrosion in the marine environment. Because of this, aluminum-magnesium alloys are widely used in building and construction, storage tanks, pressure vessels and marine applications. Examples of common alloy applications include: 5052 in electronics, 5083/5086 in marine applications, anodized 5005 sheet for architectural applications and 5182 makes the aluminum beverage can lid. The U.S. military’sBradleyFightingVehicleis made with5083and the 7xxx series aluminum.
