Abstract

The invention discloses a soft silver layer plated high-precision copper alloy wire and a manufacturing method thereof. The wire comprises a core and a plated layer. The core is prepared from, by weight, 23 to 45 parts of copper, 22 to 40 parts of carbon, 1 to 4 parts of tungsten, 4 to 11 parts of molybdenum, 1.3 to 2.4 parts of tin, 2.1 to 5.2 parts of chromium, 1.2 to 4.4 parts of neodymium, 3.3 to 3.5 parts of cerium, 3 to 6 parts of boron, 3 to 6 parts of phosphorus, 3 to 6 parts of oxygen, 8.2 to 10 parts of aluminum, 30 to 60 parts of zinc, 1.1 to 1.3 parts of zirconium, 1 to 1.5 parts of silicon, 5 to 8 parts of lead, 5 to 8 parts of arsenic and 1.5 to 4.4 parts of heat conducting padding. By the adoption of the wire and the method, when the requirements for the accuracy and the degree of finish of part machining are high, the tensile strength of the copper alloy wire is doubled, and high-drawing, high-strength and high-performance cutting is achieved; and by the adoption of the method, the steps are few, production equipment is simple, products meeting the requirements are easy to manufacture, and large-scale and automatic production is easy to achieve.

Description

technical field [0001] The invention relates to the field of copper alloy wires, in particular to a high-precision copper alloy wire with a silver-plated soft layer and a preparation method thereof. Background technique [0002] In recent years, with the need for the processing of special and complex parts such as tiny parts - tiny gears, tiny splines and tiny connectors, EDM high-precision machining is especially suitable for its unique processing method, that is, the characteristics of non-mechanical contact processing. The requirements of micro-mechanical manufacturing, and has a high cost performance, so it has played an important role in many micro-mechanical production fields, and has developed rapidly. The continuous exploration of EDM high-precision wire-cut machining technology at home and abroad has made great progress in the combination and practical application of EDM high-precision wire-cut machining with micro-mechanical manufacturing. [0003] Copper alloy ...
