   注:无铬无机后处理(Chromium-free inorganic treatment),具有以下特点:
  ① Excellent electrical conductivity The inorganic film has low electrical resistance and excellent surface conductivity (spot weldability).
  ②Corrosion resistance The resultant film has corrosion resistance equivalent to that obtained in the case of chromate treatment (A treatment).
  ③ Superior compatibility with the environment The resultant material is friendly to the environment because its film is entirely free of chromium.
