The so-called zinc alloy refers to zinc in the electroplating alloy as the main metal, its content should be more than 51% (mass percentage). In addition, it also contains one or more other metals. For example: zinc-nickel alloys (containing about 10% nickel), zinc-iron alloys (high-iron alloys and low-iron alloys, the former mass percentage is more than 7%, while the latter is <1%), zinc copper alloy (**monly known as white copper, copper mass percentage 15% to 25%).
The alloy plating means that different zinc alloy coatings are obtai** by electroplating to achieve a certain purpose.
When one or a few other small amounts of metal elements are i**oduced into the zinc coating, its performance is much better than that of the pure zinc coating. For example: zinc-nickel alloy coating (containing about l0% nickel) has higher corrosion resistance than the zinc coating alone. Widely used to replace to**c cadmium plating. The i**oduction of <1% (mass) iron or drilled metal into the coating may increase the corrosion resistance by more than three times. In addition, the zinc alloy coating also has excellent thermal stability and low hydrogen embrittlement.
