Abstract

Un alliage pour la trempe à chaud comprend de 3,5 à 5,0 % en poids de Al, de 0,05 à 0,5 % en poids de Si, de 0,01 à 0,5 % en poids de Mg, le solde étant du Zn. Un revêtement formé en utilisant cet alliage présente d'excellentes propriétés d'adhésion et de résistance à la corrosion et diminue l'élution du fer dans le bain de trempe à chaud, rendant ainsi stable la composition du bain et, par conséquent, améliorant sensiblement la maniabilité de la trempe à chaud. Des bandes d'acier plaquées de zinc en fusion et des matériaux ayant le revêtement de l'alliage de la présente invention ont d'excellentes propriétés d'adhésion du revêtement leur donnant d'excellentes propriétés d'usinabilité.
