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 preparation methods of zinc alloys have been published in the society, but these preparation methods are mostly used in casting, and are not suitable for the production of zippers, and their strength and flexibility cannot meet the requirements of zipper production.

Abstract

The invention relates to the technical field of alloys, in particular to a zinc alloy for a zipper and a preparing method of the zinc alloy. According to the zinc alloy for the zipper, the total amount of the zinc alloy serves as the standard, by weight percent, the zinc alloy for the zipper comprises following elements including 3.15%-6.21% of Al, 0.35%-1.2% of Mn, 0.56%-1.28% of Mg, 0.01%-0.08% of Sb, 0.08%-0.15% of Cu, 0.05%-0.12% of Zr, 0.06%-0.16% of V, 0.003%-0.012% of rare earth elements, and the balance Zn and inevitable impurities. A dispersed phase is formed in the zinc alloy through various metal elements, the synergistic effect is generated, and the functions of refining as cast condition grains and enhancing pinning dislocations are achieved; and accordingly, the recrystallization temperature of a zinc alloy sectional material is obviously increased, recrystallization of the grains is reduced, the problem of sensitive quenching is solved, and the strength, fracture tenacity and stress corrosion resistance of the zinc alloy sectional material are improved.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to zinc alloys used for zippers and a preparation method 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 metallic feeling and elegant material of copp...
