Abstract

A fastener (especially a screw or rivet), for fastening components of aluminium, magnesium and their alloys, consists of an AlZnMgCu type aluminium alloy of composition (by wt.) 6.0-8.0% Zn, 2.0-3.5% Mg, 1.0-3.0% Cu, 0.05-0.30% Zr, NOTGREATER 0.30% Cr, NOTGREATER 0.50% Mn, NOTGREATER 0.10% Ti, NOTGREATER 0.20% Si, NOTGREATER 0.20% Fe, NOTGREATER 0.05% each ( NOTGREATER 0.15% total) of other elements, balance Al and impurities. Also claimed is a process for producing the above fastener by casting to a billet, homogenisation annealing, compressing to a starting material, solution annealing, quenching, cold forming to fasteners and thermally hardening, in which recovery annealing is carried out at 180-260 degrees C for 5 secs. to 120 mins. prior to cold forming.
