Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0035] Select 25 example alloys and 2 comparative alloys, use induction melting or gas heating to melt the master alloy, and then use continuous casting or die casting to make a billet with a diameter of 170mm, heat it at a temperature of 180-380°C It is extruded into a bar with a diameter of 13mm, and finally processed into a finished product with a diameter of Ф12mm through cold drawing.

[0036] The tensile test at room temperature is carried out on an electronic universal mechanical performance testing machine in accordance with "GB / T228.1-2010 Metal Material Tensile Test Part 1: Room Temperature Test Method". The stretching speed is 5mm / min.

Abstract

The invention discloses a high-strength deformable zinc-based alloy material which consists of the following components in percentage by weight: 5wt%-15wt% of Cu, 7wt%-20wt% of Al, 0.01wt%-1.5wt% of Mg, 0.01wt%-2.0wt% of Cr and the balance of Zn and inevitable impurities. A microstructure of the zinc-based alloy material comprises a tiny and uniformly-distributed primary phase Epsilon, an aluminum-rich Al-Zn-Cu ternary tiny eutectoid structure and a zinc-rich Zn-Al-Cu ternary eutectic structure. The alloy material disclosed by the invention is higher than 500MPa in tensile strength, higher than 120 in HV hardness, higher than 10% in ductility and higher than 26% IACS in electric conductivity, is also good in machining properties, and can be applied to industries of power plugs, electronic and electric products, communication connectors and the like as a substitute product of traditional copper alloy, especially traditional lead brass.

Description

technical field [0001] The invention relates to a zinc-based alloy material and its application field, in particular to a high-strength deformed zinc-based alloy material, which can be used in electronics and electrical industries. Background technique [0002] For a long time, people's research and development of zinc-based alloys has been concentrated in the field of casting, and there is little research on wrought zinc alloys, especially high-strength wrought zinc alloys. However, zinc alloys including cast zinc alloys generally have low strength. The problem is that it cannot meet the current demand for high strength (above 500MPa) in the fields of electronics and electricity, and the plasticity is poor, and the machining performance is difficult to meet the requirements. [0003] Traditional die-casting zinc alloys are mainly Zn-Cu or Zn-Al binary alloys and Zn-Al-Cu systems, but their strength is generally 200-400MPa, and their hardness is generally 60-100HV, which has...
