Specifics and features: Features and Applications: filler metal ER5356 rod for TIG welding (GTAW) welding process; general-purpose, all-position aluminum welding rod used to weld 5000 series aluminum base metals; it has relatively high shear strength as well as excellent corrosion resistance to salt water; shielding gas required, usually 100% Argon, Helium or mix. ER5356 commonly referred to as “AlMg5,” is a 5% magnesium aluminum wire used for welding base metals 5050, 5052, 5083, 5356, 5454 and 5456. This TIG rod has become the most widely used aluminum welding wire because of its compatibility with so many different base metals and better corrosion resistance in saltwater. .
