Remember nickel is a poison and is banned in Australia.
Nickel is very important metal for any civilized county. Below is few
examples, which is by no means exhaustive:
Nickel Alloy Parts in Power Generation
The power generation industry relies on machines such as gas
turbines, steam turbines, and reciprocating compressors, all which
are exposed to high levels of heat and possibly corrosive steam as
well. Nickel alloy parts are used in power generation for their
ability to resist corrosion, deformation, cracking, and metal
fatigue in the presence of high temperatures.
Aerospace and Nickel Alloy
The aerospace and aviation industries rely on nickel-based
superalloys for their ability to retain strength and resist metal
fatigue in high temperatures and during drastic temperature change.
Also strong, lightweight, and aesthetic in appearance, nickel alloys
are an excellent choice for the parts and components needed for
aerospace and aviation operations.
Nickel Alloy Parts in Chemical Processing
From heat exchangers and furnaces to waste remediation units and
flares, chemical processing and petrochemical processing require
nickel alloys to resist corrosion, metal fatigue, and other problems
associated with elevated temperatures and caustic media.
Food Processing with Nickel Alloy Parts
The food processing industry requires nickel alloy parts in storage
tanks, piping, and more. Nickel alloys also have the ability to
resist abrasion or erosion by the product itself and ensure that
product remains uncontaminated.
Each and every of the above and many more expose almost everybody to
contact with Nickel in much higher degree than minute amounts used in
jewellery, so arbitrary exclusion of Nickel is nothing but a
