Aluminum Alloys 5052, with Magnesium as the main alloying element, usually called by the name marine alloy. This type of alloy used for applications such as aircraft fuel tank, rivets and wires, boats component such, and several component that needs high corrosion resistant, medium strength and high weldability.<p> <br /> <br /> <br /> <br /> <br /> There are several filler metals on the market that can be use to weld Aluminum Alloy 5052 with Tungsten Inert Gas Process, usually the most available filler metals are 4043 and 5356.<p> <br /> <br /> <br /> <br /> <br /> The market price for filler metal 4043 is only half of the filler metal 5356. By mechanical testing of both filler metal welding result, it was found that specimen B (5356) has higher average tensile strength than specimen A (4043), that is 199 Mpa compared to 184 Mpa, this was also followed by the higher average elongation and hardness of specimen B (5356).<p> <br /> <br /> <br /> <br /> <br /> Despites the higher properties of Specimen B, there is an anomaly occurred on specimen B-2, which was failed on side bend testing and resulted lower tensile strength and very low maximum elongation.<p> <br /> <br /> <br /> <br /> <br /> The whole comparation of mechanical properties resulted from both of filler metals showed that Joints made by Filler Metal 5356 always have a better mechanical properties than Joints made by Filler Metal 4043. Nevertheless, Filler metal 4043 have a better economic value than Filler metal 5356, making it more suitable and economically worthed to be used as a filler metal for any base metal with a lower tensile strength and lower elongation than Filler metal 4043.
