Nickel has a variety of applications. Its main use is an alloy material for products such as stainless steel, and it is also used for plating metals to reduce corrosion. It is used in coins as well, such as the 5 cent nickel in the US and Canada; the US nickel is made up of 25 percent nickel and 75 percent copper, while Canada's nickel has nickel plating that makes up 2 percent of its composition. Nickel's up-and-coming use is in electric vehicles as a component of certain lithium-ion battery compositions, and it has gotten extra attention because of that purpose.
