<p>The disclosed flux compositions contain by weight : from 80 to 90% of ZnCl2, from 10 to 20% of NH4Cl and, based on the weight of ZnCl2 + NH4Cl, from 0.01 to 5% of a wetting agent, from 0 to 5% of a forming agent, from 0 to 5% of a soluble salt of rare earths. The flux compositions according to the invention may be used as galvanization flux in the dry process with baths containing more than 0.15% of aluminium, particularly for baths of galvanization alloy containing 5% of aluminium, 95% of zinc and Mischmetall additions.</p> |
