The metal products on the luggage are mainly concentrated on hooks, buckles, rings, nails, as well as some LOGO brands, zipper teeth, etc. are all metal categories. Let's take a look at their characteristics according to different materials.

Generally speaking, iron materials are mostly used for connecting rings and nails on luggage. Iron products are cheap and have good flexibility and ductility. However, their chemical properties are active and they are easily affected by the outside world. After a long time, the electroplating layer is easily corroded and rusted. .

In addition, most of the hardware we see on luggage and bags are zinc alloy products. Generally speaking, zinc alloys are cast with iron and zinc in different proportions. Zinc alloys have low melting point, good fluidity, and easy Molded, and resistant to corrosion in the atmosphere, the scrap can be recycled, but at high and low temperatures, the impact properties of Nye drop significantly.
