\"\"L‘Or<\/a> est connu pour des utilisations en monnaies ou pour des transactions. Toutefois, ce m\u00e9tal pr\u00e9cieux<\/a> a aussi d’autres applications :<\/span> Une utilisation artistique<\/strong><\/span> : on estime que les \u00be de la production l’Or<\/a> servirait aux bijoux ! C’est dire l’importance de cette utilisation. Les orf\u00e8vres, les bijoutiers et les joailliers l’utilisent comme mati\u00e8re<\/strong> premi\u00e8re mais le m\u00e9langent aussi \u00e0 d’autres m\u00e9taux comme le cuivre pour faire de l’or<\/a> rouge, ou \u00e0 l’argent<\/a> et au fer. Toutefois, cette utilisation artistique n’est pas uniquement r\u00e9serv\u00e9e aux bijoux. On peut aussi en trouver dans d’autres artisanats comme pour dorer les boiseries, ou encore les reliures de livre, et le dessin sur porcelaine.<\/span> L’utilisation industrielle<\/strong><\/span> : il est clair que cette utilisation se fait de plus en plus rare. Effet de mode oblige, les stylos ou montures de lunettes se font de moins en moins en Or<\/a>. Toutefois, il retrouve un int\u00e9r\u00eat dans d’autres industries comme celle de l’informatique ou le b\u00e2timent<\/strong>, l’Or<\/a> ayant des caract\u00e9ristiques de r\u00e9sistance \u00e0 la corrosion et de haute conductibilit\u00e9 \u00e9lectrique.<\/span> Aujourd’hui, on utilise, de plus en plus, l’Or<\/a> dans les hautes technologies comme les applications spatiales<\/strong>, ou les manipulations scientifiques<\/strong>. D’ailleurs on estime \u00e0 10% cette utilisation dans les pays d\u00e9velopp\u00e9s comme le Japon ou les Etats Unis.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
