Abstract

The invention discloses a high-strength electric conduction copper rod material and a preparation method. The preparation method comprises the following steps of selecting high-purity copper, iron, silicon, chromium, aluminum, silver, sodium, zinc, lead and nickel with the purities being 99.9% or more, and putting the raw materials into a melting furnace to be molten at the melting temperature being 1100 DEG C-1200 DEG C; continuously blowing nitrogen into the raw materials and stirring the raw materials for 25-35 min to change the raw materials into molten copper; pouring molten alloy into acasting mold cavity to conduct casting; taking out the cast raw materials from the casting mold cavity and cooling the raw materials through a cooling system to form an ingot casting; and conducting secondary heating on the cooled ingot casting and conducting thermal plastic deformation on the ingot casting. According to the preparation method the raw materials are selected and are subjected to smelting, pouring and quenching treatment to be manufactured into a high-strength electric conduction copper rod, and the problem that normal use of an instrument is affected due to the fact that most of copper rods in precise instruments are common copper rods is solved.

Description

technical field [0001] The invention relates to the technical field of copper rod materials, in particular to a high-strength conductive copper rod material and a preparation method. Background technique [0002] Copper is one of the earliest metals used by humans. As early as prehistoric times, people began to mine open-pit copper mines and used the obtained copper to make weapons, tools and other utensils. The use of copper had a profound impact on the progress of early human civilization. Copper is a A metal that exists in the earth's crust and oceans. The content of copper in the earth's crust is about 0.01%. In individual copper deposits, the copper content can reach 3% to 5%. Most of the copper in nature is in the form of compounds, namely copper ore. Copper is a transition element. Pure copper is a soft metal. The surface is reddish orange with metallic luster when it is just cut. 1. Electronic components are the most commonly used materials, and they can also be use...
