Aluminum 3004

Aging Procedure

Not applicable to this alloy.

Annealing Procedure

Anneal at 650 F and air cool.

Applications

Commonly used in the manufacture of storage tanks. Is commonly used in sheet metal work.

Cold Workability

Cold working capability of this alloy is good. it can readily be cold worked up to a 75% reduction of area by conventional methods. Working beyond the 75% reduction requires an intermediate anneal.

Forgeability

Forging may be accomplished in the range of 950 to 700 F.

Formability

AL 3004 is easily formed by either cold or hot working with conventional tooling.

Hardening Procedure

Cold working is the only means of producing the harder (H) tempers of this alloy.

Heat Treatability

Heat treatment has no effect upon this alloy. It may be annealed after cold working however. See "Annealing".

Hot Workability

AL 3004 can be hot worked at temperatures of 900 to 500 F.

Machinability

The machinability of this alloy is considered to be excellent, especially in the hard temper. As is typical of the aluminum alloys an oil lubricant should be used for machining, although light cuts may be done dry.

Other Mechanical Properties

Shear strength for O temper is 16 ksi. H32 temper, 17 ksi and for H38 temper 21 ksi.

Other Physical Properties

Electrical conductivity 39% of copper.

Principle Design Features

This is an alloy of aluminum with magnesium and manganese. It is strengthened (hardened) by cold work only as it does not respond to heat treatment, other than annealing.

Tempering Procedure

Not applicable.

Weldability

The alloy is weldable by the standard methods. Best results are obtained by use of TIG or MIG welding with the same alloy as filler rod.
