Zn-5Al-MM / Zinc-5 % Aluminum-Mischmetal / Galfan
Zinc Galvanizing Alloys
Galfan is a type of steel that is coated with a zinc-aluminum layer instead of the traditional galvanized steel zinc layer because the zinc-aluminum layer has superior corrosion resistance. This superior corrosion resistance allows thinner layers of protective coating to be applied.
Galfan, Zn-5Al-MM alloy ingot for hot dip coatings may contain up to 0.002%, 0.1% and 0.05% of antimony, copper and magnesium, respectively. No harmful effects were observed due to the presence of these elements up to these concentrations and therefore analysis for these elements is not required.
