Eu zic ca nu...

Static and dynamic immersion trials with various detergents, disinfectants and household cleaners as well as soft tap water showed that ZA-12 is adequate for drainage fittings and only slightly inferior to 63/37 brass.
Engine coolants. Typically a 33% solution of Prestone II in water (an engine coolant solution which contains silicate inhibitors) will not attack No.3 and ZA-8 castings. The ZA-27 alloy displayed intergranular attack when tested as-cast, but not when its surface was polished before testing.
