What is pitting corrosion and how does it happen? Pitting corrosion is in itself a corrosion mechanism, but is also a form of corrosion often associated with other types of corrosion mechanisms. It is characterised by a highly localised loss of metal. In the extreme case, it can appear as a deep, tiny hole in an otherwise unaffected surface.
Forged Nickel Alloys Forged Nickel for Excellent Corrosion- & Wear-Resistance. With the ability to withstand intense temperatures, nickel alloys are used for forgings that need to weather the most severe environments and, therefore, must be wear-resistant as well as corrosion-resistant.
Formation of nickel. Generally, there are two types of occurrences of nickel ore that are magmatic sulphides and laterites. Magmatic sulphide type ore bodies are generally extracted by underground mining while laterites are being extracted by surface mining.
Discovery of Nickel. Nickel is present in metallic meteorites and so has been in use since ancient times. Artifacts made from metallic meteorites have been found dating from as early as 5000 BC – for example beads in graves in Egypt.

Nickel Poisoning. Nickel is a ductile metal, silver in color (for which reason it was mistaken, for a long time, for silver) and relatively hard. It has been used for millennia, but it was first isolated in mid-18 th century and named for a German legendary mining character. It was initially isolated from cupronickel, but later other sources became known.
