A rotating magnet heater for metal products, such as aluminum strip, can include permanent magnet rotors arranged above and below a moving metal strip to induce moving or time varying magnetic fields through the metal strip. The changing magnetic fields can create currents (e.g., eddy currents) within the metal strip, thus heating the metal strip. A magnetic rotor set can include a pair of matched magnetic rotors on opposite sides of a metal strip that rotate at the same speed. Each magnetic rotor of a set can be positioned equidistance from the metal strip to avoid pulling the metal strip away from the passline. A downstream magnetic rotor set can be used in close proximity to an upstream magnetic rotor set to offset tension induced by the upstream magnetic rotor set.

Disclosed are aluminum alloy products and methods of making and processing such products. Thus, disclosed are aluminum alloy products exhibiting controllable surface properties, including excellent bond durability, low contact resistance, and corrosion resistance. Aluminum alloy products described herein include a migrant element, a subsurface portion having a concentration of the migrant element, and a bulk portion having a concentration of the migrant element. The aluminum alloy product comprises an enrichment ratio of 4.0 or less, wherein the enrichment ratio is a ratio of the migrant element concentration in the subsurface portion to the concentration in the bulk portion. Additionally, the aluminum alloy products surface and/or subsurface can contain phosphorus (e.g., elemental phosphorus or oxidized phosphorus). The phosphorus containing surface provides reduced electronic stress on an electrode tip of a resistance spot welding apparatus, and an extended service lifetime (e.g., weld cycles to failure) of the electrode tip.
