Precipitation Hardening of the Electrical Conductor Aluminum Alloy 6201

Aluminum alloy 6201 is a wrought, heat-treatable alloy, which used in electricity transmission and distribution lines. The processed commercial continuous casting rolling system, includes series of in-line thermomechanical processes involving hot working, quenching, cold working artificial aging. In this study following the subjected to solution heat treatment at 510 °C for an hour, quenched ice water, artificially aged various temperatures times (150–200 2–30 h) (T6-temper) order investigate effect precipitation on mechanical properties electrical conductivity. results show that optimum conductivity were obtained after aging 155 30 h (155-30). tensile strength was almost equal as received drawn wire 326 MPa, but interestingly, significantly increased 58.6% IACS from value 52.7% wire. Intermetallic particles α-AlFeSi (Al8Fe2Si) β-AlFeSi (Al5FeSi Al9Fe2Si2) observed all samples, nucleated during solidification homogenization; they not affected by process. β″/β′/β -precipitates formed aging, final
