Titanium vs. Nickel Alloys: Cost-Effective Choice for Salt Refining Equipment

The selection of materials for salt refining equipment represents a critical decision that directly impacts operational efficiency and lifetime costs. While nickel alloys have been traditionally specified for corrosive environments, modern titanium grades are increasingly demonstrating superior cost-effectiveness in salt production applications.

In evaporation systems and brine heaters where temperatures exceed 100°C and chloride concentrations reach saturation levels, both materials offer excellent corrosion resistance. However, titanium provides distinct advantages that translate into long-term economic benefits. Its lower density—approximately 60% that of nickel alloys—enables lighter support structures and easier installation. More importantly, titanium's exceptional resistance to pitting and crevice corrosion in hot chloride solutions ensures consistently smooth surfaces that maintain heat transfer efficiency throughout extended service periods.

The lifecycle cost analysis reveals titanium's true value proposition. While initial material costs may be comparable to high-performance nickel alloys, titanium equipment typically delivers 30-50% longer service life in severe salt refining conditions. This extended operational lifespan, combined with reduced maintenance requirements and superior heat transfer characteristics, results in significantly lower cost per operating year.

Modern titanium grades also demonstrate better fabrication characteristics than commonly perceived. Advanced welding techniques and improved formability have made titanium equipment increasingly competitive in initial fabrication costs while maintaining their traditional advantages in operational durability.
