Chinese patent CN98112410.0 discloses a copper-aluminum composite wire, which is metallurgically combined with a layer of copper outside the aluminum core to improve the processing performance and applicability of the aluminum wire; the aluminum material of the copper-clad aluminum core wire is soft but has low tensile strength. Low, high cost, and low melting point, so it is not suitable for the power cable industry; Chinese patent 00124464.7 discloses a production method of copper-clad steel bimetallic composite wire, which is to coat a layer of copper on the outside of the steel wire, and then Pull into the required wire
The low-carbon steel required for copper-clad steel needs to be highly purified, so the processing cost is high. Its material is hard and has high elasticity and is not easy to bend. It is only suitable for the communication cable industry. It is not suitable to use this composite material instead of copper wire in the electronics industry. , so there is a certain limitation

Abstract

The invention relates to a composite wire with 99.90%~99.98% sheath copper and ferroalloy core composed by 20-40% copper and 60-80% iron. Wherein, the wire diameter is 0.08-10mm, and the manufacture method comprises: cladding the copper on ferroalloy wire with diameter as 6-14mm to prepare composite blank; with different speed and reducing rate, drawing with a wire-drawing die on drawbench repeatedly to complete the process. This invention reduces cost and environmental pollution, and enlarges the application of copper / steel-clad steel.

Description

Technical field [0001] The invention relates to a metal composite wire, in particular to a copper-clad iron composite wire. Background technique [0002] From the perspective of mineral resources, the global copper resources are relatively tight, and iron resources are particularly rich and almost inexhaustible resources, which can eliminate the worries of enterprises in the supply of raw materials, from the social benefits of resource use and the saving of copper resources. From the point of view, the use of bimetallic materials as conductors for communication and power transmission also has very practical significance. Chinese patent CN98112410.0 discloses a copper-aluminum composite wire, which is metallurgically combined with a layer of copper outside the aluminum core to improve the processing performance and applicability of the aluminum wire; the aluminum material of the copper-clad aluminum core wire is softer but has tensile strength Low, high cost, low melting point, so...
