Why limit N.A.Brz to warm seawater?
That was not the intent. N.A.Brz is at least equal to or superior to Ferrilium, Duplex SS, 316 SS, type 2 Ni-resist or any of the cold water (North Sea) popular materials when compared mechanically or for corrosion resistance. Up untill now, (before the availability of Badenoch Bronze) these materials were less expensive than N.A.Brz. For example: the Navies ot the world use N.A.Brz exclusively.
