(a) Phase diagram of binary Fe-Ni alloy (Composed from data in [7-9]); (b) influence of nickel alloying on the transformation temperature of 0.1 wt.% carbon steel upon re-austenitizing using data
These materials have a high electrical resistance and therefore should not be used for conductors of electrical current. Monel* (67 percent nickel, 30 percent copper): This material is the least expensive of the nickel-base alloys. It also has the lowest tensile strength but is useful due to its resistance to the corrosive effects of seawater
The alloy of 90% copper and 10% nickel, remarkable for its resistance to corrosion, is used for various objects exposed to seawater, though it is vulnerable to the sulfides sometimes found in polluted harbors and estuaries. Alloys of copper with aluminium (about 7%) have a golden color and are used in decorations.
Alloy 20 resisted corrosion by the alternating conditions of an alkaline environment when the soap enters the tank and the hot, acidic environment created when acid and steam are added to produce the tall oil. Comparable alloys, such as 904L (UNS N08904) provide acceptable resistance as does the nickel-based Alloy G-30 (UNS N06030).
Not always. Since brass is an alloy (a metal made by combining at least two metallic elements), it has the potential to have nickel mixed into it. Sterling silver? Not always. Sterling silver is just 92.5% pure, which may sound high, but even if just a little bit of nickel is used to make sterling silver, people with allergies will suffer. Gold

For the most demanding applications, such as high pressure turbine blades and vanes, precipitation strengthened alloys are required. Most nickel-based alloys contain 10–20 % Cr, up to 8 % Al and Ti, 5–10 % Co, and small amounts of B, Zr, and C. Other common additions are Mo, W, Ta, Hf, and Nb.
Alloy steel is a type of steel with alloying elements other than carbon added to improve its properties. Some of the common additions to alloy steel include: chromium, cobalt, columbium, molybdenum, manganese, nickel, titanium, tungsten, silicon, and vanadium. Alloy steels are known for their enhanced properties compared to plain-carbon steel
– Invar is a ferrous alloy Ferrous alloys – those of which iron is the prime constituent - are produce in larger quantities than any other metal type – Remember that steels and cast irons are iron-carbon alloys (0.25% - 6.7% carbon, majority iron) – As already mentioned Invar is iron-nickel alloy
Nickel is also used in nichrome, a name for a nickel-chromium alloy, and other alloys. Nickel is used in magnets. Nickel is used in special expensive alloys called superalloys. Nickel sulphate is used in rechargeable batteries. A lithium ion battery contains up to 15% of nickel while the lithium content is less than 1%.
