2. Marinisation - Wikipedia

   en.wikipedia.org/wiki/Marinisation

   Marinised metals include some of the following: . Non-corrosive alloys that resist or are impervious to salt-water corrosion, e.g. 316 marine grade stainless steel; brass (an alloy of copper and zinc), or bronze (which contains copper with tin in place of zinc).

3. Noble metal - Wikipedia

   en.wikipedia.org/wiki/Noble_metal

   "Noble Metals. Gold, Platinum, Silver, and a few rare metals. The members of this class have little or no tendency to unite with oxygen in the free state, and when placed in water at a red heat do not alter its composition. The oxides are readily decomposed by heat in consequence of the feeble affinity between the metal and oxygen." [29]

4. Stainless steel - Wikipedia

   en.wikipedia.org/wiki/Stainless_steel

   Stainless steel (bottom row) resists salt-water corrosion better than aluminium-bronze (top row) or copper-nickel alloys (middle row). Unlike carbon steel, stainless steels do not suffer uniform corrosion when exposed to wet environments. Unprotected carbon steel rusts readily when exposed to a combination of air and moisture.

5. Salt water chlorination - Wikipedia

   en.wikipedia.org/wiki/Salt_water_chlorination

   Salt water chlorination is a process that uses dissolved salt (1000–4000 ppm or 1–4 g/L) for the chlorination of swimming pools and hot tubs.The chlorine generator (also known as salt cell, salt generator, salt chlorinator, or SWG) uses electrolysis in the presence of dissolved salt to produce chlorine gas or its dissolved forms, hypochlorous acid and sodium hypochlorite, which are already ...

6. Non-ferrous metal - Wikipedia

   en.wikipedia.org/wiki/Non-ferrous_metal

   In metallurgy, non-ferrous metals are metals or alloys that do not contain iron (allotropes of iron, ferrite, and so on) in appreciable amounts.. Generally more costly than ferrous metals, non-ferrous metals are used because of desirable properties such as low weight (e.g. aluminium), higher conductivity (e.g. copper), [1] non-magnetic properties or resistance to corrosion (e.g. zinc).
