Aluminum 3003

Aging Procedure

Not applicable to this alloy.

Annealing Procedure

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

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.

Cold Workability

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

Forgeability

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

Formability

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

Hardening Procedure

Hardens as a result of cold working only.

Heat Treatability

AL 3003 is a non-heat treatable alloy.

Hot Workability

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

Machinability

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

Other Mechanical Properties

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

Other Physical Properties

Electrical conductivity 40% of copper.

Principle 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.

Tempering Procedure

Not applicable.

Weldability

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.
