Deformed zinc alloy with high plasticity as well as preparation method and application thereof

Abstract

The invention discloses a deformed zinc alloy with high plasticity as well as preparation method and application thereof. The deformed zinc alloy comprises the following components in percentages by weight: 0.1%-5% of Cu, 0.01%-2% of Ti and the balance of Zn and unavoidable impurities. A microstructure of the deformed zinc alloy comprises an Eta phase and an Epsilon phase, wherein the Eta phase is a solid solution in which zinc is replaced by copper and the Epsilon phase is composed of copper-zinc intermetallic compounds and zinc-copper-titanium intermetallic compounds. The deformed zinc alloy disclosed by the invention is a multiphase material which utilizes a matrix phase and a second phase to ensure high plasticity and appropriate strength and hardness of the material. Extensibility of the deformed zinc alloy is 26-40%, conductivity is 24-29% IACS, tensile strength is 201-348MPa and section shrinkage ratio is 41-56%, so that the deformed zinc alloy is capable of meeting cold-forging or riveting performance requirements of power plugs and inserts to act as a substitute material for a traditional brass alloy.

Description

technical field [0001] The invention relates to a zinc alloy material and its application field, in particular to a deformed zinc alloy with high plasticity and its preparation method and application. The alloy material can be applied to electrical industries such as power plugs and inserts and other related industries. Background technique [0002] Power plugs and blades are electrical products widely used in daily life and industrial production. At present, most power plugs and blades are made of copper alloy. The main requirements for the power plug are: (1) Excellent electrical conductivity, no dangerous phenomena such as overheating and high temperature rise will occur during long-term high-current use; (2) Good mechanical properties, because the power plug on the same product Large quantities, high-efficiency manufacturing and assembly methods are very important for improving production efficiency, so the requirements for high-speed cutting and crimping of materials ar...

AI Technical Summary

Problems solved by technology

However, because zinc is a close-packed hexagonal structure crystal, the cast zinc alloy is relatively brittle, and the deformed zinc alloy (rod, wire, etc.) Although the alloy has certain plasticity, but the strength is low

The processing performance of cast zinc alloy is poor, and it cannot be used to process and manufacture electrical products such as power plugs and inserts; the existing deformed zinc alloy, its comprehensive performance indicators including plasticity are difficult to meet the processing and use of power plugs and inserts Require
