WELDING RODS The ER 1100 aluminum welding rod is used for welding commercially pure aluminum and aluminum- manganese alloys. It has approximately the same tensile strength as pure aluminum in the annealed state (about 12,000 psi). The ER aluminum welding rod is used for welding all but the pure aluminum manganese alloys. Do not use this rod on aluminum alloys such as Grades EC, 1060, 1100, and 3003 if high corrosion resistance is required. On strong aluminum alloys, the weld strength will vary with the alloy being welded and the methods of heat-treating and quenching. However, sound welds made with this rod can be expected to reach tensile strengths between 25,000 and 30,000 psi.
