- Main Performances Of The Electrode Materials
| Electrode Material | Application |
| SUS316L |
Applicable to industrial/municipal water, wastewater and low corrosive mediums. Widely used in petroleum, chemical industries. |
| Hastelloy B |
Strong resistance to hydrochloric acids below the boiling point. Resist against oxidable acids, alkali and non-oxidable salts. For instance, vitriol, phosphate, hydrofluoric acids, and organic acids. |
| Hastelloy C |
Exceptional resistance to strong solutions of oxidizing salts and acids. For example, Fe+++, Cu++, Nitric acids, mixed acids |
| Titanium |
Titanium can withstand corrosive mediums such as seawater, chloride salt solutions, hypochlorite salts, oxidable acids(including fuming nitric acids), organic acids, and alkali. Not resistant to high purity reducing acids such as sulphuric acids, hydrochloric acids. |
| Tantalum |
Highly resistant to corrosive mediums. Applicable to all chemical mediums except Hydrofluoric Acids, Oleum and Alkali. |
| Platinum-iridium | Applicable to all chemical mediums except for Ammonium salts and Fortis. |
