Abstract

The invention discloses a high-strength and high-toughness copper-zinc alloy wire material and a preparation method thereof, and relates to the technical field of copper-zinc alloys, and the high-strength and high-toughness copper-zinc alloy wire material comprises the following raw material components in percentage by weight: 2wt%-4wt% of zinc, 0.01 wt%-0.03 wt% of rare earth elements and the balance of copper. The high-strength and high-toughness copper-zinc alloy wire material is reasonable in proportion of copper, zinc and rare earth elements in the raw material components, low in gas content, few in inclusions, uniform in structure component, free of macroscopic and microcosmic defects such as copper and zinc enrichment and the like, high in corrosion resistance, high in strength and high in toughness.

Description

technical field [0001] The invention relates to the technical field of copper-zinc alloys, in particular to a high-strength and high-toughness copper-zinc alloy wire material and a preparation method thereof. Background technique [0002] Copper-zinc alloys have excellent processing properties and are widely used in various fields. Although copper-zinc alloys have low raw material cost, high corrosion resistance, and good mechanical properties, they have poor mechanical properties, low strength, and poor toughness. Improving the strength of copper-zinc alloys by adding other metal elements will produce defects such as enrichment of copper and zinc elements. [0003] At present, there is no copper-zinc alloy wire material and preparation method on the market, which can meet the requirements of high strength and high toughness, and no macroscopic and microscopic defects such as copper and zinc enrichment. Contents of the invention [0004] Aiming at the defects in the prio...
