Ces m\u00e9taux sont g\u00e9n\u00e9ralement s\u00e9lectionn\u00e9s pour des conditions exigeantes impliquant une temp\u00e9rature \u00e9lev\u00e9e, une r\u00e9sistance \u00e0 la corrosion, la densit\u00e9, des propri\u00e9t\u00e9s \u00e9lectriques, un service sous vide, une compatibilit\u00e9 chimique ou des exigences particuli\u00e8res de conception industrielle. L'approvisionnement d\u00e9pend fortement de la nuance ou de la puret\u00e9, de la forme du produit, des dimensions, de la tol\u00e9rance, de l'\u00e9tat de surface, de l'exigence de densit\u00e9 le cas \u00e9ch\u00e9ant et de la voie finale d'usinage ou de fabrication.
