Nickel<\/h3>\n

Le nickel est un m\u00e9tal brillant blanc argent\u00e9 avec une l\u00e9g\u00e8re teinte dor\u00e9e.\u00a0Le nickel fait partie des m\u00e9taux de transition et est dur et ductile.

L’\u00e9tain est un m\u00e9tal post-transition du groupe 14 du tableau p\u00e9riodique.\u00a0Il est obtenu principalement \u00e0 partir de la cassit\u00e9rite min\u00e9rale, qui contient du dioxyde d’\u00e9tain.\u00a0Le premier alliage utilis\u00e9 \u00e0 grande \u00e9chelle \u00e9tait le bronze, compos\u00e9 d’\u00e9tain et de cuivre, d\u00e8s 3000 av.<\/p>\n<\/div>

Nickel et \u00c9tain – Applications<\/h2>\n<\/div><\/div>\n

\n

Nickel<\/a><\/h3>\n

La production mondiale de nickel est actuellement utilis\u00e9e comme suit: 68 % en acier inoxydable; 10 % en alliages non ferreux; 9 % en galvanoplastie; 7 % en acier alli\u00e9; 3 % dans les fonderies; et 4 % d’autres utilisations (y compris les piles). Le nickel est utilis\u00e9 comme constituant de diff\u00e9rents types d’alliages; par exemple, Monel (mat\u00e9riau r\u00e9sistant \u00e0 la corrosion), Nichrome (un alliage utilis\u00e9 pour les \u00e9l\u00e9ments chauffants \u00e0 r\u00e9sistance), Permalloy (un alliage \u00e0 haute perm\u00e9abilit\u00e9 magn\u00e9tique \u00e0 faible intensit\u00e9 de champ et faible perte d’hyst\u00e9r\u00e9sis), cupronickel, acier inoxydable, maillechort, etc. Les alliages \u00e0 base de nickel (par exemple les alliages Fe-Cr-Ni(Mo)) pr\u00e9sentent une excellente ductilit\u00e9 et t\u00e9nacit\u00e9, m\u00eame \u00e0 des niveaux de r\u00e9sistance \u00e9lev\u00e9s et ces propri\u00e9t\u00e9s sont conserv\u00e9es jusqu’\u00e0 de basses temp\u00e9ratures. Le nickel et ses alliages sont tr\u00e8s r\u00e9sistants \u00e0 la corrosion dans de nombreux environnements, notamment ceux qui sont basiques (alcalins). Le nickel r\u00e9duit \u00e9galement la dilatation thermique pour une meilleure stabilit\u00e9 dimensionnelle. Le nickel est l’\u00e9l\u00e9ment de base des superalliages. Ces m\u00e9taux ont une excellente r\u00e9sistance \u00e0 la d\u00e9formation par fluage thermique et conservent leur rigidit\u00e9, leur r\u00e9sistance, leur t\u00e9nacit\u00e9 et leur stabilit\u00e9 dimensionnelle \u00e0 des temp\u00e9ratures beaucoup plus \u00e9lev\u00e9es que les autres mat\u00e9riaux de structure a\u00e9rospatiaux.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n

\u00c9tain<\/a><\/h3>\n

La principale application de l’\u00e9tain est la fabrication de fer-blanc (t\u00f4le d’acier rev\u00eatue d’\u00e9tain), qui repr\u00e9sente environ 40 % de la consommation mondiale totale d’\u00e9tain.\u00a0L’\u00e9tain adh\u00e8re facilement au fer et \u00e0 l’acier pour pr\u00e9venir la corrosion.\u00a0Les r\u00e9cipients en acier \u00e9tam\u00e9 sont largement utilis\u00e9s pour la conservation des aliments, ce qui constitue une grande partie du march\u00e9 de l’\u00e9tain m\u00e9tallique.\u00a0L’\u00e9tamage est le processus de rev\u00eatement mince de feuilles de fer forg\u00e9 ou d’acier avec de l’\u00e9tain, et le produit r\u00e9sultant est connu sous le nom de fer-blanc.\u00a0Le terme est \u00e9galement largement utilis\u00e9 pour les diff\u00e9rents processus de rev\u00eatement d’un m\u00e9tal avec de la soudure avant le soudage.\u00a0Il existe deux proc\u00e9d\u00e9s d’\u00e9tamage des plaques noires : le trempage \u00e0 chaud et la galvanoplastie.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n
