  • Process for producing tinned copper wires
    Patent number: 11898253
    Abstract: Provided is a process for producing a tinned copper wire. The process comprises subjecting a copper wire sequentially to activation treatment, a first hot tinning treatment, a first cooling, a second hot tinning treatment, and a second cooling to obtain a tinned copper wire. The first hot tinning treatment is carried out at a first temperature and the second hot tinning treatment is carried out at a second temperature. The first temperature is higher than the second temperature. The first temperature is at least 38° C. higher than the melting point of tin. The second temperature is at least 8° C. higher than the melting point of tin.
