铜及铜合金钝化液
Passivation solution for copper and copper alloys
1.适用于电解铜箔、铜合金（紫铜、磷铜、黄铜等）及镀铜产品的钝化防氧化处理。
2.环保无铬，常温浸泡，操作简便，兑水比例高、使用寿命长。
3.钝化后不改变工件外观、颜色、光泽与尺寸，不影响导电及焊接性能，实现绿色防护与品质兼得。
1.Suitable for anti-oxidation passivation treatment of electrolytic copper foil, copper alloys (e.g., pure copper, phosphor copper, brass), and copper-plated products.
2.Environmentally friendly and chromium-free, applied via room-temperature immersion for easy operation, with a high dilution ratio and long service life.
3.Does not alter the appearance, color, luster, or dimensions of workpieces after passivation, nor does it affect electrical conductivity or solderability, achieving both green protection and high quality.
