The alloy comprises the following componentsin percentage by weight: 0.2-0.5 wt.% of Ca, 1.0-1.2 wt.% of Sn, 1.0-3.0 wt.% of Mg, 0.2-1.2 wt.% of Ge, 0.2-0.4 wt.% of Cu, 0.1-0.2 wt.% of Mo, 1.2-1.4 wt.% of Ni, 1.0-5.0 wt.% of W, and the balanceof zinc. The alloy for hot-dip galvanizing is suitable for a ceramic crucible production process in hot-dip galvanizing; and the product achieves the effects of reduction of abnormal consumption of zinc and cost saving.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a zinc alloy. Background technique [0002] Steel has the advantages of good strength, formability, economical production and recyclability, and occupies a very important position in the process of industrial construction. However, steel easily reacts with the environment to form stable oxides or salts. Corrosion of steel reduces the service life of steel, brings huge economic losses to human beings, and seriously pollutes the environment. Therefore, people have adopted various protective technologies to improve the anticorrosion performance of steel. [0003] Since the standard electrode potential of zinc is negative to that of iron, the galvanized layer has the effect of sacrificial anode protection of the steel base in water and humid air, which can greatly prolong the service life of the steel. The galvanized layers commonly used in industry include hot-dip galvanized, elect...
