The zinc bath, which is particularly useful for batch-wise galvanizing steel articles, contains 3-15 wt.% of tin, lead at a concentration up to saturation and 0-0.06 wt.% of at least one of aluminium, calcium and magnesium, the rest being zinc and unavoidable impurities in order to diminish the influence of the silicon content of the steel to be galvanized on the coating thickness.
Le bain de zinc qui est particulièrement utile pour galvaniser, en lots, des articles en acier, contient 3 à 15 % en poids d'étain, du plomb à une concentration pouvant atteindre la saturation et 0 à 0,06 % en poids d'au moins un élément parmi de l'aluminium, du calcium et du magnésium. Le reste est constitué par du zinc et des impuretés inévitables afin de réduire l'influence de la teneur en silicium de l'acier à galvaniser sur l'épaisseur de revêtement.
