FIELD: metallurgy.
SUBSTANCE: melt contains 0.7 - 3.4 wt % of magnesium, 0.01 - 0.1 wt % of silver, 0.84 - 4.08 wt % of aluminium, and zinc is the rest. At that, ratio of aluminium to magnesium in the melt is maintained in the ratio of 1.2:1.
EFFECT: invention allows improving the quality of the coating, its hardness, reducing accumulation rate of lower kish and production costs.
