These include materials such as: cupronickel
, aluminium bronze, aluminium nickel bronze and a range of electro-plated blanks, as well as more exotic alloys aimed at achieving very specific objectives such as: colour, electromagnetic properties and wear characteristics.
Many 1903 carbines had deeper grooves, perhaps due to the cupronickel
jackets commonly used on early smokeless bullets.
Thermoplastic coatings also allow for the use of standard steel instead of expensive Cupronickel
Nowadays, the demand for the high-performance cupronickel

, constantan (very similar to cupro-nickel), Inconcl and aluminum.
The Diamond Jubilee medal is set to be cupronickel

If copper is used for tubes and cupronickel
is used in tube sheets in seawater-cooled condensers, copper tubes will corrode.
The proposed change would save the Royal Mint, in Llantrisant, South Wales, as much as pounds 8m a year as the "silver" coins would be made from steel instead of cupronickel
- an alloy of copper and nickel.
