    Smile can't identify the root cause of the rust

    Hi guys,

    Give the reasons of rust form on the copper-alloy. Beyond the liquid, atmosphere condition.

    Corrosion - you need oxygen and metal, or two materials at different galvanic potential and a path between the materials.

    Eliminate any one of the above three to stop the corrosion.

    Tell me and I forget. Teach me and I remember. Involve me and I learn.
