ER5554 is an aluminum filler metal that contains more manganese and zinc with slightly more magnesium than Washington Alloy 5356. This gives ER5554 good ductility and improved crack resistance. This alloy may be used for MIG or TIG welding processes. Commonly used on base metals 5154, 5254, 5454 and 5456. The approximate melting range is 1065°-1175°F and the post-anodizing color tint will be white. The ultimate tensile strength will be approximately 46,000 psi.
