Abstract:
    The present invention relates to process of making zinc-base alloy wire and rod with high strength and high toughness. The production process includes the steps of providing zinc-base alloy material with Al content not less than 10 wt%, smelting, heat preservation and extruding at 300-450 deg.c, drawing, heat treatment at 150-300 deg.c for 30-120 min, and quenching. The production process can obtain zinc-base alloy wire and rod of different sizes for producing various mechanical parts, such as screw, nut, pull rod, wire, etc.
