Abstract
A method of making a corrosion-resistant string for a musical instrument. The method improves the core wire-to-wrap wire bond by using a bond coating between the core and wrap wires that preferably also minimizes the galvanic activity between them. The bondable coating is applied to the core or wrap wires, or both. In one embodiment the method entails creating a coated core wire by annealing bare core wire, bathing the bare core wire in a bondable coating material and removing any excess, drying the bondable coating, making the string using the bondable-coated core wire, and reflowing the bondable coating. In another embodiment the method entails additionally coating the wrap wire with a coating that does not reflow under the same conditions as the bondable coating on the core wire, and winding the coated wrap wire around the bondable-coated core wire before reflowing the bondable coating.
