In the United States and Canada, a nickel is a coin worth five cents. Metallic chemical element, one of the transition elements, chemical symbol Ni, atomic number
A hard, malleable, ductile metal It occurs naturally in all parts of the environment including plants and animals It is used in alloys, electrical catalysts for hydrogenation of oils, coins, and magnetic and electrical contacts Nickel can be soluble or insoluble in water depending on the chemical and physical properties of the water body In soil, it is extremely persistent It can cause dermatitis, and ingestion can cause nausea and vomiting Nickel is a Group A, human carcinogen
a hard malleable ductile silvery metallic element that is resistant to corrosion; used in alloys; occurs in pentlandite and smaltite and garnierite and millerite plate with nickel; "nickel the plate
A silvery, hard, ductile, ferromagnetic, metallic element used in alloys, in corrosion-resistant surfaces and batteries, and for electroplating Nickel is one of the heavy metals found in the Earth's core
Occurs naturally in soils, groundwater and surface waters and is often used in electroplating, stainless steel, and alloy products It generally gets into water from mining and refining operations Measured in µg/L or ppb The MCL for nickel is 0 1 mg/L or ppm The Health Advisory Level is 200 µg/L or ppb
(and compounds) Used to coat metals and in the production of batteries Acute exposure can cause irritation of the skin Nickel is associated with increased risk of nasal and lung cancer It has also caused reproductive disease in animals
a silver-white hard malleable ductile metallic element capable of a high polish and resistant to corrosion that is used chiefly in alloys and as a catalyst
Nickel is silvery white, tough, harder than iron, ferromagnetic (see ferromagnetism), and highly resistant to rusting and corrosion. It occasionally occurs free and is fairly common but not often concentrated in igneous rocks. As pure metal, it is used to coat other metals (see plating) and as a catalyst. In alloys, it is used in coins, Monel metal, nickel silver, nickel-chrome and stainless steels, permanant magnets, and cutlery. Its compounds, in which it most often has valence 2, have a variety of industrial uses, as catalysts and mordants (see dye) and in electroplating
This metal offers combination of corrosion resistance, formability and tough physical properties For these reasons, nickel is used for alloying purposes and in nickel-clad copper wire
Nickel is a silver-white hard malleable ductile metallic element capable of a high polish and resistant to corrosion It is used chiefly in alloys and as a catalyst
(Chemical symbol Ni) Element No 28 of the periodic system; atomic weight 58 69 Silvery white, slightly magnetic metal, of medium hardness and high degree of ductility and malleability and resistance to chemical and atmospheric corrosion; melting point 2651 (degrees) F ; boiling point about 5250 (degrees) F , specific gravity 8 90 Used for electroplating Used as an alloying agent, it is of great importance in iron-base alloys in stainless steels and in copper-base alloys such as Cupro-Nickel, as well as in nickel-base alloys such as Monel Metal Its principal functions as an alloy in steel making: (1) Strengthens unquenched or annealed steels (2) Toughens pearlitic-ferritic steels (especially at low temperature) (3) Renders high-chromium iron alloys austenitic
One of the most widely used alloying elements in steel In amounts 0 50% to 5 00% its use in alloy steels increases the toughness and tensile strength without detrimental effect on the ductility Nickel also increases the hardenability, thus permitting the steel to be oil- hardened instead of water quenched In larger quantities, 8 00% and upwards, nickel is the constituent, together with chromium, of many corrosion resistant and stainless austenitic steels
a United States coin worth one twentieth of a dollar five dollars worth of a drug; "a nickel bag of drugs"; "a nickel deck of heroin" a hard malleable ductile silvery metallic element that is resistant to corrosion; used in alloys; occurs in pentlandite and smaltite and garnierite and millerite plate with nickel; "nickel the plate
