HOT DIP TINNED GUITAR WIRE WITH BRASS UNDERCOATING AND PROCESS FOR THE SAME

摘要

The present invention relates to a guitar wire used for an electric guitar and an acoustic guitar. A brass plating layer containing 55-70% of copper and 30-45% of zinc is formed at a thickness of 0.1-0.5 m on a surface of a steel wire. A hot dip tinning coating layer is formed on the brass plating layer. The total thickness of the brass plating layer and the hot dip tinning coating layer is at a thickness of 5 m or thinner, thus an excellent appearance quality and improved plating efficiency are obtained. The manufacturing method of the steel wire for a spree includes: a step of primarily dry-drawing a material wire rod at a diameter of 2.0-4.0 mm; a step of secondarily dry-drawing the wire rod at a diameter of 0.5-2.5 mm after thermal treatment of the primarily dry-drawn steel wire; a step of forming the brass plating layer on a surface of the secondarily drawn steel wire; a step of thirdly drawing the steel wire to make the final length of the wire 0.1-1.0 mm and the thickness of the brass coating layer 0.1-0.5 m; and a step of forming the dip tinning coating layer by passing the thirdly drawn steel wire through a plating bath for hot dip tinning. The purpose of the present invention is to provide the brass undercoated hot dip tinned guitar wire with excellent appearance and gloss properties and a manufacturing method thereof.
