Embodiment 19

[0070] According to the design ratio, it is melted in an induction furnace with a melting temperature of 500-600°C and a refining temperature of 600-750°C. It is refined with a commercially available refining agent. After the refining is completed, a φ50 casting rod is continuously cast horizontally.

[0071] The chemical composition analysis results of the cast rod are as follows (% by weight): Cu 2.425 Al 2.072 Mg 0.100 Bi0.0001 Ni0.13%, Si 0.056%. The balance is Zn.

[0072] The cast rod is sawed and cut to the designed length, kept at 300°C for 2 hours, and then extruded into a billet of φ8.0. The extruded billet is stretched through multiple passes, stretched to a flattened round billet, and undergoes 2 times of annealing and rapid cooling in the middle. It is then flattened to a flat wire stock, with an annealing in between. The flat wire blank is rolled and drawn to make a flat wire with a specification of 0.9×3.95. The produced flat wire is discharged on the rice di...

[0085] After the ingot is wagoned, it is kept at 300°C for 2 hours, and then extruded into a billet with a diameter of φ8.0, and the extrusion ratio is not greater than 100. After 2 times of annealing and rapid cooling in the middle. It is then flattened to a flat wire stock, with an annealing in between. The flat wire blank is rolled and drawn to make a flat wire with a specification of 0.9×3.95. The produced flat wire is discharged on the rice discharge machine, and the zipper tape is s...

Abstract

Disclosed are a zinc alloy for zipper chain and a method for producing zipper chain. The zinc alloy is composed of 0.5-5 wt.% of copper, 0-4.5 wt.% of aluminum, 0.01-0.2wt.% of magnesium, and the balance X, Y, zinc and inevitable impurities. The X is at least one selected from the group consisting of 0.0001-0.5 wt.% of Bi, 0.01-0.19 wt.% of Ti, 0.001-0.3 wt.% of RE, 0.001-1 wt.% of Ni and 0.001-1 wt.% of Si. The Y is at least one selected from the group consisting group of Mn, Co, Nb, Zr, Cr, Ca, P, Sb, Te and Se.

Description

technical field [0001] The invention relates to a zinc alloy and an application thereof, in particular to a zinc alloy for a zipper tape and a method for preparing the zipper tape. Background technique [0002] The invention and application of zippers have a long history. At present, there are many varieties and styles of zippers, which are widely used in daily life such as clothing, shoes and hats, bags, tents, toys, etc., bringing great convenience to people. . A simple zipper involves cloth tape, chain teeth, upper and lower buckles, sliders and accessories, and each item involves different materials. Chain tooth materials are the most used materials, mainly metal, plastic and nylon, and the metal materials used are mainly copper alloys. Commonly used copper alloys are brass such as H65, H68, H85, H90 and BZn12-24 zinc white copper, and the market demand is very large. Copper alloys account for about 70% of the cost of zippers, and cost and resource issues are graduall...
