Aviation wire rope is suitable for aviation machinery, as well as important machinery and instruments. It is characterized by high tensile strength, good wear resistance, fatigue resistance, softness and long service life. The main structures are: 1×7, 1×19, 6×7+IWS, 6×19+IWS, 6×7+FC, 6×19+FC, 6×37+FC. The products strictly comply with YB/T5197-2005 "Aviation Wire Rope" standard. The aviation steel wire rope here has a galvanized surface treatment. Therefore, our experienced wire rope engineers generally call galvanized steel wire rope aviation wire rope.

In fact, aviation steel wire rope specifically refers to galvanized steel wire rope with a strength above 1960!


Function of galvanized steel wire rope: Galvanized steel wire rope is mainly used as a lifting wire rope for anti-corrosion and anti-rust purposes.


Galvanized steel wire ropes are divided into two categories: cold-dip galvanized steel wire ropes and hot-dip galvanized steel wire ropes. There is an essential difference in process between hot-dip galvanizing and cold-dip galvanizing.


Differences in process of galvanized steel wire rope


Electro-zinc plating is a coating obtained by electrodeposition by applying an external power supply. The obtained coating is composed of fine pure zinc grains. Cold galvanizing (or electro-galvanizing) is zinc plated by electroplating or other methods at room temperature. Theoretically, a zinc layer of any thickness can be obtained by electroplating zinc. At present, the practical amount of zinc for electroplating can reach 1200g/m2. , the amount of zinc on the general electroplated zinc layer can also reach 750g/m2.


Hot-dip galvanizing relies on physical thermal diffusion to form a coating. First, an iron-zinc compound is formed, and then a pure zinc layer is formed on the surface of the iron-zinc compound. The amount of zinc on hot-dip galvanizing is only 593g/m2. Hot-dip galvanizing will reduce the mechanical properties of the steel wire. Galvanized steel wire ropes that require high strength and high corrosion resistance are often twisted by electro-galvanized steel wire. Hot-dip galvanizing is zinc plated in molten zinc liquid at 450-480 degrees.
