Alternative Designations : AS 1050; BS 1050A (formerly SIB); DIN AI 99.5: EN AW-1050A: JIS A1050P: NF 1050A (formerly NF A5).
Note : Profiles products are routinely produced to AA specifications, but other National Standards may be met on request.
Chemical Composition :
(% max except where a range is given)
Typical Uses : General Sheet metal work where moderate strength is adequate; lightly stressed panels; architectural flashings; name plates; lamp reflectors; brightly polished trim; cable sheathing; equipment and containers for food and chemical industries.
Note : Special grades are available for deep drawings, low earing, spinning and anodising: general purpose grades should not be used for these applications.
Modulus of Elasticity : 69,000 Mpa
Bend Radii : Minimum Recommended radii for 90 degeree Cold bends

Welding : 1050 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.
1050 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 dissortion 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.
