DescriptionAluminium 5356 Mig Wire 1.2mm x 2Kg ReelAs a basic description we can say that 4043 is an aluminium filler alloy with 5% silicon added and that 5356 is an aluminium filler alloy with 5% magnesium added. There are some misconceptions within the industry that you can successfully weld any aluminium base alloy with either 4043 or 5356 filler alloy. we must start by saying that this is not the case. However, there are many common structural aluminium base alloys that can be welded with either 4043 or 5356. One such alloy is 6061. The question here is when should we choose one of these filler alloys over the other? When the filler alloy selection chart allows the use of either 4043 or 5356 as filler for a specific base alloy, as a guide, we may wish to consider the following facts about each of these filler alloys. Aluminium 5356 Mig Wire 1.2mm x 2Kg Reel4043 should not be used if you are considering the best colour match after post weld anodizing, as this filler alloy will typically turn dark gray in colour after the anodizing process. 5356 will provide a much closer colour match after anodizing.4043 is suitable for service temperatures above 150 Deg. F, however, 5356, because of its 5% magnesium content is not suitable for these elevated temperature applications.4043 has lower ductility than that of 5356. This may be of some consideration if forming, after welding is to be carried out.4043 has lower shear strength than that of 5356 (see Fig 1). This may be of consideration when calculating the size of fillet welds.4043 is a softer alloy in the form of spooled wire, when compared to 5356. Typically when Gas Metal Arc Welding (GMAW), feedability will become a less critical issue when feeding the more rigid 5356 alloy.4043 will typically provide a higher rating for weldability and provide slightly lower crack sensitivity. 4043 will generally tend to produce welds with improved cosmetic appearance, smoother surfaces, less spatter and less smut. For this reason, it is sometimes more appealing to the welder.Features and Applications • A general purpose Aluminium wire containing 5% magnesium, giving excellent corrosion resistance and high joint strength • Shipbuilding and offshore, power generation, repair and maintenance and railway industry.
