Une transformation de phase martensitique thermo\u00e9lastique au sein du mat\u00e9riau est \u00e0 l&#039;origine de ses propri\u00e9t\u00e9s exceptionnelles. Les alliages de nitinol sont g\u00e9n\u00e9ralement compos\u00e9s de nickel 55%-56% et de titane 44%-45%. De faibles variations de composition peuvent avoir un impact significatif sur les propri\u00e9t\u00e9s du mat\u00e9riau. Il existe deux grandes cat\u00e9gories de nitinol.<\/p>\n<p>L&#039;alliage nickel-titane, plus commun\u00e9ment appel\u00e9 Nitinol, est un mat\u00e9riau haute performance caract\u00e9ris\u00e9 par sa transformation de phase martensitique thermo\u00e9lastique unique. Cette propri\u00e9t\u00e9 lui conf\u00e8re un effet de m\u00e9moire de forme et une super\u00e9lasticit\u00e9, lui permettant de retrouver une forme pr\u00e9d\u00e9finie apr\u00e8s chauffage ou sa forme initiale apr\u00e8s une d\u00e9formation importante. Ces propri\u00e9t\u00e9s m\u00e9caniques adaptatives font du Nitinol un mat\u00e9riau id\u00e9al pour les applications de pr\u00e9cision. Cet alliage est g\u00e9n\u00e9ralement compos\u00e9 de nickel (55-56%) et de titane (44-45%), et m\u00eame de l\u00e9g\u00e8res variations de sa composition peuvent avoir un impact significatif sur ses performances.<\/p>\n<div class=\"dzx-row\">\n<div class=\"dzx-col-media\">\n<div class=\"left_pics\"><\/div>\n<\/div>\n<div class=\"dzx-col\">\n<div class=\"protitle\">Fil de nitinol (ASTM F2063)<\/div>\n<p>Notre <strong>Fil de nitinol de haute qualit\u00e9<\/strong> Con\u00e7u pour des applications de pr\u00e9cision, ce mat\u00e9riau offre une super\u00e9lasticit\u00e9 et des propri\u00e9t\u00e9s de m\u00e9moire de forme exceptionnelles.
