COPPER-PALLADIUM ALLOY WIRE FORMED BY SOLID-STATE DIFFUSION REACTION AND MANUFACTURING METHOD THEREOF

摘要

The invention relates to a copper-palladium alloy wire formed by a solid-state diffusion reaction and a manufacturing method thereof. Primarily, the method comprises the steps of preparing a core wire, coating a palladium containing layer on the core wire made of copper or copper alloy, and allowing the core wire coated with the palladium containing layer to be subject to vacuum heat treatments, so that the palladium containing layer is fully diffused to a matrix of the core wire, and a uniform copper-palladium alloy layer is formed in the organization of the core wire.
