Note:
H2-temper designations indicate that a different process
has been used to achieve mechanical characteristics similar to
those of the corresponding H1-tempers. However, property limits
of H2-tempers differ from the above in that the Maximum Tensile
Strength and Minimum Yield Strength provisions do not apply. Where
required, material supplied in H2-tempers can be produced to meet
the mechanical property limits of the equivalent H1-tempers.
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: 3003
is readily welded by the TIG and MIG processes. Commonly used
filler alloys are 4043 and 1100. 4043 gives a greater weld strength,
but if the assembly is to be anodized, 1100 filler metal will
give a closer color match.
3003 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: 415ºC
± 5ºC, until all parts have reached the annealing temperature.
Weight Calculation:
Weight per square metre in kilogrammes: 2.73 x
thickness in mm.
