Description

technical field [0001] The invention relates to the technical field of alloy wire manufacture, in particular to a copper alloy wire and a preparation method thereof. Background technique [0002] Because copper alloy has many excellent properties, it has a wide range of uses in the national economy, such as machinery, electronics, automobiles, electric power, communications, transportation and light industry sectors, the consumption of copper wire is very large. Copper alloy wire is divided into brass wire, bronze wire and white copper wire according to the alloy grade. In recent years, the alloy varieties of copper alloy wires have increased rapidly, and the utilization space of bronze, cupronickel and special alloy wires is much higher than that of ordinary brass wires, and has become a hot spot in the development of wire rods. The main varieties of copper alloy wires include cap lead brass wires, bronze wires for patch cords, ballpoint pen core wires, mirror frame wires,...
