Note:
An alternative method of production, designated H2X, may be used
instead of the H1X routes, subject to agreement between supplier
and purchaser and providing that the same specified properties
are achieved.
(1) BS 1470 does
not specify minimum elongation for gauges under 0.50mm. The limit
to be applied shall be subject to agreement between supplier and
purchaser.
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:
1200 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.
1200 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: 350ºC ± 5ºC, until
all parts have reached the annealing temperature.
Weight Calculation:
Weight per square metre in kilogrammes: 2.71 x thickness in mm.
