Principal Design Features		AL 3003 is an alloy with very good corrosion resistance and moderate strength. It is not heat treatable and develops strengthening from cold working only.

Applications		Commonly used in chemical equipment, ductwork, and in general sheet metal work. 3003 is also used in the manufacture of cooking utensils, pressure vessels, builder's hardware, eyelet stock, ice cube trays, garage doors, awning slats, refrigerator panels, gas lines, gasoline tanks, heat exchangers, drawn and spun parts, and storage tanks.

Machinability		The AL 3003 alloy is readily machined and is considered as having good machinability for the aluminum alloys,.

Forming		This alloy is readily formed by either conventional cold working or hot working.

Welding		Welding is readily accomplished by means of conventional welding methods. Filler rod is generally AL 1100 alloy. When welding AL 3003 to other aluminum alloys, such as 5052, 6061 or 6062 the filler rod should be AL 4043.

Heat Treatment		AL 3003 is a non-heat treatable alloy.

Forging		The alloy may be hot forged in the range of 950 F to 500 F.

Hot Working		The hot working range (as for forging) is 950 F to 500 F. In that range the alloy is easily hot worked.

Cold Working		AL 3003 alloy is readily cold worked by all conventional methods..

Annealing		Annealing, during or following cold working, is done at 775 F, allowing adequate time for thorough heating, followed by air cooling.

Aging		Not applicable to this alloy.

Tempering		Not applicable.

Hardening		Hardens as a result of cold working only.

Other Physical Props		Electrical conductivity 40% of copper.

Other Mechanical Props		Shear strength for O temper (annealed) is 11 ksi. For H14 (cold worked) it is 14 ksi.
