Corrosion Resistance Table
Titanium:Perfect for all of the corrosion resistance(Sea water, Natural air,Nitrogen...)
Chronium: used to plate metal (Example:Stainlesssteel-Steel+Chronium15%
Copper:  Only weak to Sea water
Tin: usually use as plating iron(protect iron to react
Alumium: less oxidize than iron
Iron: oxidize well, so there are many material for plating iron
Zinc: usually use as plating iron(react earlier than iron)
