Problems solved by technology

[0003] However, the existing nickel-plated alloy wire rods also have some shortcomings in actual use, such as poor product stability, easy peeling of the coating, and dull surface of the coating. The main reason is that the alloy layer formed by the nickel coating and the copper substrate is not uniform enough. , the bonding strength of the coating is not enough; in addition, as far as the application in some industrial fields such as the electronics industry and the aerospace, railway and other industries with special requirements, the ductility and corrosion resistance of the existing nickel-plated copper wire products in the nickel coating , high temperature resistance, color change resistance, etc. also need to be further improved

Abstract

The invention discloses a nickel alloy copper wire and a preparation method thereof, a copper core is coated with a silver coating, the silver coating is coated with a nickel alloy layer, the nickel alloy layer is coated with an outer protective layer, and the method comprises the following process steps: (1) burdening according to Ni, Zn, Mg, Mn and Si, smelting, refining, and pouring to obtain an ingot; forging and rolling into a wire rod; and then conducting multi-pass drawing annealing treatment and drawing circulation machining, and obtaining a soft finished product. electroplating silveron the copper wire material in an electroplating mode; electroplating nickel-chromium alloy or nickel-copper alloy or nickel-cobalt alloy; washing in hot pure water, performing ultrasonic cleaning, and coating with an outer protective layer to obtain the nickel alloy copper wire. The surface of the nickel alloy layer is covered with the outer protective layer, the corrosion resistance and high temperature resistance of the wire are improved, the whole wire has good plasticity, mechanical property, toughness, electrical property and weldability and is resistant to oxidation, the service life is greatly prolonged, and the using effect is also improved.

Description

technical field [0001] The invention belongs to the field of metallurgical industry, in particular to a nickel alloy copper wire and a preparation method thereof. Background technique [0002] With the rapid development of the global economy, the demand for coated wires in the fields of transportation, energy and power, electronics and electrical has shown a trend of sharp increase. At present, the well-known plated wire products on the market are mainly tin-plated, nickel-plated and silver-plated. Among them, nickel-plated wires, especially nickel-plated alloy copper wires, have better corrosion resistance, wear resistance, lubricity, hardness, etc. , electrical conductivity and good appearance properties are more favored by users. Because nickel has good corrosion resistance and high temperature resistance, it is easy to passivate in the air, can withstand strong alkali, and has a slow interaction with hydrochloric acid and sulfuric acid, so the nickel layer on the nickel...
