ER5356 (commonly referred to as ALMg-5) is a 5% Magnesium Aluminum Alloy filler metal that is used to weld Aluminum Alloys 5050, 5052, 5083, 5356, 5454, and 5456. ER5356 Aluminium Filler Wire is a popular wire owing to its strength and good corrosion resistance. Provides excellent colour match after anodising. Although suitable for many 5000 and 6000 series alloys when used to weld alloys such as 5083 and 5456 the minimum 275MPa strength may not be achieved and if the higher strength is required an alternative such as ER5183 or ER5556 should be used. The Salt Water corrosion resistance of ER5356 Aluminium Welding Wire is very good also, making it an ideal choice for many marine applications.


ER5356 Aluminium Welding Filler Wire has become the most commonly used of all filler wire because of its compatibility with most base alloys, its good strength, and its good feed ability when used as a GMAW electrode wire. ER5356 Welding Wire is used in various applications like boats, ships, bicycles, trucks, pressure vessels, and automotive parts and equipment. This filler wire has one important limitation, which is its unsuitability at service temperatures exceeding 150 degrees F. This is due to the formation of Al2Mg at elevated temperatures at the grain boundaries, which makes the alloy prone to stress corrosion.
