Embodiment Construction

[0016] Referring to FIG. 1 , the copper-silver alloy wire 1 according to the first embodiment of the present invention includes a core wire 10 and a copper-silver alloy layer 11 covering the outer surface of the core wire 10 .

[0017] The material of the core wire 10 can be copper or brass. The silver content in the copper-silver alloy wire 1 can be 1-30% of the copper.

[0018] For the content of silver in the copper-silver alloy wire 1 , selecting greater than 1% is to consider its electrical conductivity and the strength of the wire. When the silver content is greater than 1%, the electrical conductivity of the copper-silver alloy wire 1 can be greater than 80% IACS (International Annealed Copper Standard). Because the silver content in the copper-silver alloy wire is too high, the strength will decrease and the wire cannot be used effectively, so the silver content should not be higher than 30% of the copper. Considering the cost, the content of silver can be less than ...

Abstract

This invention relates to a CuAg alloy lead including a core and a CuAg alloy layer, and the core can be made of Cu or Cu base alloy, and the lead includes many layers having the advantage of high conductivity, prevention of electromagnetic and RF interference and little loss of eddy current. This invention also provides a preparation method for CuAg alloy lead.

Description

【Technical field】 [0001] The invention relates to a copper-silver alloy wire and a manufacturing method thereof, in particular to a copper-silver alloy wire which can be used as a signal line of electronic equipment, a power transmission line and the like. 【Background technique】 [0002] Wires play a very important role in various electronic devices. They can be used as signal input / output lines or power transmission lines. The stable operation of electronic products requires wires to have high conductivity, low loss and high anti-interference ability. [0003] In order to improve the conductivity of the wire, the wire is generally made of a material with high conductivity. Pure copper or pure silver has high electrical conductivity, but the hardness of pure copper and pure silver is too low, and it is difficult to extract pure metals, and the cost is high, especially silver is a precious metal, and the cost is higher. Therefore, the wires actually used today mostly use cop...
