Rivet Wire, Aluminum

Optimum strength combined with sufficient ductility for forming of non-heat treatable alloy wire is achieved by drawing a limited reduction, usually 10 to 20 percent from the last in­termediate anneal to finish size. With heat-treatable alloys, solution treatment is carried out after the rivet head has been formed, and if annealed wire is used, part of the shank immediately below the head has coarse grain in a most undesirable position after heat treatment.
