Welding : 1060 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.
1060 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 : 350°C ± 5°C, until all parts have reached the annealing temperature.
Weight Calculation : Weight per square meter in kilogrammes: 2.71 x thickness in mm.
