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: 1100
is readily welded by the TIG and MIG processes. Commonly used
filler alloys are 4043 and 1050. 4043 gives a greater weld strength,
but if the assembly is to be anodized, 1050 filler metal will
give a closer color match.
1100 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: 2.71 x
thickness in mm.
