Aluminium alloys in the 5xxx series of Al-Mg alloys are readily weldable, have good corrosion resistance in marine conditions, but with higher Mg content cold work and ageing can lead to sensitisation to SCC. Alloy 5083 can be used in marine environments without coatings etc provided it is not sensitised to corrosion. The study assessed the performance of welds in alloy 5454 (2.6%Mg) and 5083 (4.6%Mg) produced by MIG w…See more on twi-global.comsp.info Wheeler Tank Manufacturing, Inc.Call us today at. 1 (800) 888-9526. <. >.
