Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] Selected 20 embodiment alloys and 2 comparative example alloys, adopt the inventive method to prepare respectively:

[0033] 1) Accurately weigh each raw material required for preparing the deformed zinc alloy material according to the proportioning ratio;

[0034] 2) Produce ingots by hot-top casting, semi-continuous casting or horizontal continuous casting. During the casting process, 80% of zinc ingots are first put in, and after complete melting, the temperature is raised to 650-900°C, and then the remaining 20% ​​of zinc ingots and For other raw materials, heat up to 500-650°C, then add degasser and modifier, stir after complete melting, remove slag, take samples for component analysis, draw cast and saw cut after passing, and obtain 400-700mm in length ingots;

[0035] 3) Will The ingot is heated to 200-300°C, and then extrud...

Abstract

A readily cold-formable deformable zinc alloy, having the following composition in percentage by weight: 1.0-3.5 wt% of Cu, 0.05-0.5 wt% of Mn, and ≤ 0.05 wt% of Al, the balance being Zn and unavoidable impurities. The phase composition of the deformable zinc alloy material comprises a Cu-substituted Zn solid solution with Zn as a matrix, a second phase of Zn5Cu, and a second phase of a zinc-manganese-copper intermetallic compound. The deformable zinc alloy material has a tensile strength of 260-320 MPa, an elongation of 25-35%, and an HV5 hardness of 90-100. The deformable zinc alloy material has medium strength, high elongation, and good dimensional stability, and its total processing rate can reach 80-90%.

Description

technical field [0001] The invention relates to the technical field of deformed zinc alloy and its application, in particular to a deformed zinc alloy material which is easy to be cold-formed and its preparation method and application. Background technique [0002] Cold processing technology is a processing method in which blanks are quickly processed into parts with various complex structures through various molds, such as cold heading, cold forging, spinning, riveting, etc. Compared with the traditional turning technology, cold working can improve the utilization rate of materials, reduce loss and improve product production efficiency, and the structure of cold processed products is uniform and dense, which can be widely used in various standard parts products. Cold processing has become the first choice for metal material processing important means. However, cold working has a large amount of deformation on metals, and general metals are work-hardened materials. Therefor...
