Discussion On The Corrosion Resistance Of Pre-twisted Wire

armor rod preformed Long-term exposure to outdoor environments may cause corrosion of metal parts such as steel wire or aluminum-clad steel wire due to moisture, salt spray, acid and alkali and pollutants in the air.

preformed armour rod is usually made of metal material that is the same as or compatible with the wire material, so that an electrochemical corrosion cell will not form between the metals. Using identical or compatible materials inhibits electrochemical reactions and delays metal oxidation and corrosion.

Some armor rods conductors also enhance corrosion resistance through anti-corrosion coatings. These coatings use acid and alkali resistant, weather-resistant, and salt spray-resistant materials to isolate corrosive media from contact with the metal surface. After coating application, even minor scratches on the surface can, to some extent, compensate for the metal's exposure to corrosive media, extending its service life.
