What is zinc-iron alloy

Zinc-iron alloy plate is also called alloyed galvanized plate. In the alloying process, galvanized strip steel is heated to 550~560℃ in the alloying furnace 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. The corrosion resistance of the alloy coating after passivation is more than three times that of the zinc layer.

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

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

Zero zinc flower N Z adopts a specific production process to make the coating surface without visible zinc flowers. Zinc-iron alloy R ZF coating is zinc-iron alloy layer, no zinc flowers, generally no luster.

Its alloy has many valuable physical, chemical, mechanical properties, such as high strength and toughness, excellent corrosion resistance, good electric vacuum properties, with ferromagnetism.

By alloying, it can be made into high temperature alloy 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.

Early automobile with zinc alloy more, such as gasoline pump, carburetor and so on the largest use is the automobile.

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