Copper fin material for heat-exchanger and method of producing the same. |
摘要 |
<p>A copper fin material for heat-exchanger characterized in that, on the surface of Cu or Cu alloy strip, an inner side diffused layer comprising Cu and Zn and a surface side diffused layer being provided on the surface side thereeof and comprising Cu, Zn and elements with a lower diffusion coefficient into Cu than that of Zn are formed is disclosed. A method of producing the same is characterized in that, after an alloy film comprising elements with a lower diffusion coefficient into Cu than that of Zn and Zn was formed on the surface of Cu or Cu alloy strip, a diffusion treatment is given under heat so that, on the surface of Cu or Cu alloy strip, an inner side diffused layer comprising Cu and Zn and a surface side diffused layer being provided on the surface side thereof and comprising Cu, Zn and elements with a lower diffusion coefficient into Cu than that of Zn are formed, or the diffusion treatment under heat and the rolling processing are given.</p> |
