Problems solved by technology

Otherwise, problems such as cracks, punching burrs, crushing, crushing, broken teeth, deformation, and poor bite force may occur, and cannot be used.
[0004] At present, a large number of zinc alloy preparation methods have been announced in the society, but these preparation methods are mostly used in casting, and are not suitable for the production of zippers. Their corrosion resistance is poor, and their comprehensive performance is lacking, so they cannot meet people's needs.

Abstract

The invention relates to the technical field of metal material smelting, in particular to a corrosion-resistant zinc alloy used for making zippers and a preparation process thereof. In percentage terms, the corrosion-resistant zinc alloy used to make zippers contains the following elements: Al 1.17-3.48%, Zr 0.008-0.21%, B 0.89-1.75%, Mg 1.25-3.71%, Ni 1.21-3.81%, Cu 0.08 ~0.36%, Ti 0.26~0.84%, Ta 0.005~0.12%, C 0.05~0.26%, rare earth elements 0.01~0.03%, and the rest are Zn and unavoidable impurities. In the present invention, various metals are formed in the zinc alloy system Alloy dispersed phase, and produce a synergistic effect, refine the as-cast grains, strengthen the role of pinning dislocations, thereby significantly increasing the recrystallization temperature of zinc alloy profiles, reducing the recrystallization of grains, and improving the zinc alloy strength, fracture toughness and stress corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of metal material smelting, in particular to a corrosion-resistant zinc alloy for making zippers and a preparation process thereof. Background technique [0002] Zippers are widely used in clothing, luggage and other daily life. They are generally divided into plastic zippers, nylon zippers and metal zippers. Metal zippers are divided into three types: aluminum zippers, copper zippers and zinc alloy zippers. Most of the commonly used copper zippers. However, the cost of copper is high, and copper alloy accounts for about 70% of the cost of zippers. Cost and resource issues will make it gradually eliminated, while the punch of aluminum zippers is fragile, the material utilization rate is low, and it is difficult to color, and the processing technology is complicated. The product rate is high, and the strength is lower than that of copper. Zinc alloy material has high strength, easy to color, and has the meta...
