High-flexibility copper rod and preparation method thereof

Abstract

The invention discloses a high-flexibility copper rod and a preparation method thereof. Copper and titanium are compounded to prepare a copper-based alloy, the flexibility and strength of the material are improved, zirconium is added in the compounding process, titanium is dissolved in the copper in a solid mode, meanwhile, diffusion of the titanium element on a grain boundary can be hindered through addition of zirconium, and thus the heat resistance of the titanium-copper alloy is remarkably improved; the titanium-copper alloy and boron are crushed and then sintered under high pressure, so that secondary recombination of the grain boundary is performed, the boron located at the grain boundary inhibits continuous precipitation of beta-Cu4Ti at the grain boundary during sintering, intergranular fracture is reduced, and the flexibility is improved; the addition of the Mg-Zn-Al alloy inhibits non-uniform nucleation of an equilibrium phase of the titanium-copper alloy at the grain boundary, twin boundary, dislocation and other defects, so that grains are more regular, meanwhile, distribution of a second phase is improved, the hot brittleness of the alloy is eliminated, the metal strength is improved, and the mechanical property of the alloy is improved.

Description

technical field [0001] The invention relates to a copper rod with high flexibility, and also relates to a preparation method of the copper rod. Background technique [0002] Copper, because of its good ductility, good electrical and thermal conductivity, antimagnetic, durable and easy to recycle, is widely used in electric power, light industry, machinery manufacturing, construction industry, defense industry and other fields, but because of its relatively low flexibility Poor, poor hardness, copper can not be widely used in many new industries, in response to the development of the three major industries of aerospace, construction, and automobiles, the need for better diversification of the preparation of copper rods requires a better mechanical properties, flexibility A better brass rod. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a copper wire with good elect...
