>>About COPPER
The Nickel is used in many industrial and
consumer products, including stainless steel, magnets, coinage,
rechargeable batteries, electric guitar strings and special alloys. It
is also used for plating and as a green tint in glass.
The amounts of nickel used for various applications are 60% used for
making nickel steels, 14% used in nickel-copper alloys and nickel
silver, 9% used to make malleable nickel, nickel clad, Inconel and other
superalloys, 6% used in plating, 3% use for nickel cast irons, 3% in
heat and electric resistance alloys, such as Nichrome, 2% used for
nickel brasses and bronzes with the remaining 3% of the nickel
consumption in all other applications combined.
In the laboratory, nickel is frequently used
as a catalyst for hydrogenation, most often using Raney nickel. Nickel
is often used in coins, or occasionally as a substitute for decorative
silver. The American 'nickel' five-cent coin is 75% copper and 25%
nickel. Various other nations have historically used and still use
nickel in their coinage.
Nickel is also used in fire assay as a collector of platinum group
elements, as it is capable of full collection of all 6 elements, in
addition to partial collection of gold. |
