Note:
3004 is an alloy which spontaneously softens after rolling until
it reaches a stable condition. This process is accelerated by
means of a stabilising anneal, giving the material an H3-temper.
For this reason, 3004 is normally supplied in the H3-temper in
which the stable condition is achieved before shipment.
Modulus of Elasticity:
69,000 MPa
Bend Radii:
Minimum recommended internal bend radii
for 90º cold bends at right angle to the rolling direction.

Welding:
3004 is readily welded by the TIG and MIG processes. Commonly
used filler alloy is 4043. 3004 may also be gas welded or resistance
welded, but the resulting joints are not as strong or as corrosion
resistant as the inert gas welded joints. Moreover, gas welding
could result in excessive heat distortion and, in thinner gauges,
may burn through. It is essential that all traces of flux used
in welding or brazing are removed by scrubbing with hot water
upon completion.
Annealing:
345ºC ± 5ºC, until all parts have reached
the annealing temperature.
Weight Calculation:
Weight per square metre in kilogrammes: 2.72 x thickness in mm.
