It is unlikely that it has better corrosion properties than a cheaper copper alloy, like copper-nickel alloy. This new alloy is useful only for high-temperature applications, like turbines and heat exchangers, where its main advantage over the existing alloys (based on nickel or cobalt) is its much higher thermal conductivity. Moreover, the kinds of stainless steel that have little or no nickel content (e.g. ferritic, martensitic, superferritic, duplex, manganese-austenitic) will always have a price several times lower than any copper alloy. This copper alloy will be rather expensive due to the high cost of tantalum. However the content in tantalum is small, so the price will remain acceptable for its applications.
