What is zinc-iron alloy?

 Zinc-iron alloy plate is also called alloyed galvanized plate. The alloying process heats the galvanized strip through the alloying furnace to 550~560 ° C in 5~10 seconds in order to convert the pure zinc layer into an iron-zinc alloy. Its weldability, coating performance, heat resistance, corrosion resistance are better than ordinary galvanized sheet.

Performance and characteristics

1. Suitable for alkaline low iron zinc iron alloy process, coating iron content 0.3 ~ 0.8%;

2. Fine crystal coating, brightness is white;

3. The alloy coating is easy to passivation, and the corrosion resistance of the alloy coating after passivation is more than three times that of the zinc layer passivation;

4. Stable plating solution, easy to maintain, can be hung plating or roll plating (including automatic line);

5. The cost is relatively low, and the original equipment can be used to turn the original zincate galvanizing liquid into a trough.

Use

By alloying, it can be made into superalloy or super alloy, corrosion resistant alloy, high resistance alloy, electric vacuum alloy and other materials with special properties. Widely used in aerospace, aviation, shipbuilding, electronics, electrical, machinery, chemical, electroplating and other industrial sectors.

In the early days, there were more zinc-iron alloys in automobiles, such as gasoline pumps, carburetors, and so on.

Because the surface galvanized liquid contains iron, so the welding performance is better than ordinary galvanized, also has rust resistance and corrosion resistance, the application is very wide.
