Abstract

The invention discloses a high-performance galvanized copper alloy wire rod and a preparation method thereof. The high-performance galvanized copper alloy wire rod comprises a core material and a clad layer. The core material is prepared from the following raw materials of, by weight, 2.3-4.4 parts of germanium, 1.3-2.4 parts of tin, 5-8 parts of lead, 3-6 parts of nickel, 1-4 parts of tungsten, 1.3-5.1 parts of silver, 2.1-5.2 parts of chrome, 2-4 parts of aluminum, 30-50 parts of copper, 2-6 parts of cobalt, 4-11 parts of molybdenum, 1.2-4.4 parts of neodymium, 3.3-3.5 parts of cerium, 2-4 parts of carbon and 10-12 parts of thermal conductive fillers. According to the high-performance galvanized copper alloy wire rod and the preparation method thereof, the corrosion resistance of a wire in machining fluid is increased, the cutting performance of the wire is improved significantly, and the obtained wire has the stable tensile strength; the wire rod is provided with a certain copper-zinc alloy layer, so that the gasification temperature is increased, and more heat is conducive to being taken away; the operability is high; the preparation steps are few; the production equipment is simple, therefore, products meeting the requirements are prepared easily, and the large-scale production and the automatic production are achieved easily.

Description

technical field [0001] The invention relates to the field of copper alloy wires, in particular to a high-performance galvanized copper alloy wire and a preparation method thereof. Background technique [0002] The core material is ordinary brass, and the surface is coated with zinc. Due to the gasification effect of zinc during cutting, the discharge of this copper alloy wire will be relatively stable, and the cut surface will be smoother than ordinary brass wire. However, the common problem in the use of this copper alloy wire is powder falling, which is also faced by domestic and foreign manufacturers. [0003] The principle of EDM is to remove excess metal based on the electric corrosion phenomenon of pulsed spark discharge between the tool and the workpiece (positive and negative electrodes) in a certain medium, so as to achieve the size, shape and surface quality of the parts. Wait for the scheduled processing requirements. EDM is mainly used in mold manufacturing, ...
