Typical Uses: Boatbuilding and other marine applications; automotive parts; transportation equipment; unfired pressure vessels; cladding of structures and tanks in severe environments. 5086 is especially favoured for marine uses because it combines high resistance to corrosion in sea water with strength in the annealed condition, giving superior "as welded" properties.

Note: 5086 is an alloy which spontaneously softens after rolling until it reaches a stable condition. This process is accelerated by means of a stabilising anneal, giving the material an H3-temper. For this reason, 5086 is normally supplied in the H3-temper, in which the stable condition is achieved before shipment.

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: 5086 is readily welded by the TIG and MIG processes. The filler alloy is 5356. Welding 5086 in the H32, H34, H36 or H38 will reduce the tensile and yield strengths in the heat affected zone to those of the annealed condition.

5086 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.
