Abstract
The invention relates to a copper tinned aluminum wire and a production method thereof and tinning equipment in the production process. The copper tinned aluminum wire comprises an aluminum core, a copper layer clad outside the aluminum core, wherein a tin layer is plated outside the copper layer; and the aluminum core is made of high-purity aluminum or aluminum alloy. The copper tinned aluminum wire has solderability, sulfurization resistance, and conductivity of a tinned copper wire, and saves the copper consumption. In the production method of the copper tinned aluminum wire, hot tinning process is used for substituting the prior electric tinning process, and no waste water is produced and discharged in the entire production process, thereby obviating environment pollution. The tinning equipment adopts a diamond mold for applying tin and determining diameter to simply the tin plating step and obtain a tin layer with better adhesion and more uniform thickness. Accordingly, the copper tinned aluminum wire has better surface light intensity.
