Abstract

The invention belongs to the technical field of copper-clad steel wire, and specifically relates to a high-flexibility copper-clad steel wire. The high-flexibility copper-clad steel wire comprises a low carbon steel layer, a pure iron layer, a copper plating layer, outer arc-shaped bending plates and inner arc-shaped bending plates; the pure iron layer is arranged at the outer part of the low carbon steel layer and wraps the low carbon steel layer; four outer arc-shaped bending plates which are prepared from 304 stainless steel are uniformly arranged in the pure iron layer in the circumference direction; the copper plating layer is arranged at the outer part of the pure iron layer and wraps the pure iron layer; the low carbon steel layer contains 0.2 to 0.25% of carbon; the pure iron layer contains 0.02 to 0.03% of carbon content. According to the high-flexibility copper-clad steel wire, the outer arc-shaped bending plates and the inner arc-shaped bending plates are provided to improve the flexibility and the fatigue resistance; the social benefit and economic benefit are increased.

Description

technical field [0001] The invention belongs to the technical field of copper-clad steel, and in particular relates to a highly flexible copper-clad steel wire. Background technique [0002] Copper-clad steel, as the name implies, is a copper-clad steel wire, that is, a composite wire wrapped with a copper layer around the steel wire. It uses the skin effect of low-voltage high-frequency signals to walk along the surface in the high-frequency area, so as long as the thickness of the copper layer reaches a certain range, Signals in a certain frequency band can be guaranteed to be delivered. The copper plays the role of conducting weak electric signals, and the steel wire plays a supporting role. [0003] According to different methods of wrapping copper onto steel wire, it is mainly divided into electroplating, cladding, hot casting / dipping and electroforming. At present, the copper-clad steel on the market basically adopts the electroplating process, that is, the electropl...
