Are hot dip zinc whiskers immune?Are hot dip zinc whiskers immune?"While the empirical information that can be found 'publicly' states overwhelming that zinc whiskers are limited to finishes applied via 'electroplating' and that 'hot dip galvanized zinc coatings' are immune, we have heard some rare reports of zinc whiskers forming on 'hot dip galvanized' surfaces as well."Zinc Whiskers in a Data Center - Pregalvanized, Hot-dipped Zinc Whiskers on Hot Dip Galvanized Steel Pipe Can you put zinc in galvanized steel?Can you put zinc in galvanized steel?Simply put, neither allow for the formation of zinc whiskers. While hot-dipped galvanization still involves coating steel in zinc, it creates a layer of zinc that's under far less pressure than one produced through the electroplating process.What are Zinc Whiskers and How Can They be Prevented? What is zinc whiskers?What is zinc whiskers?Zinc whiskers "grow" on steel surfaces that have been electroplated (galvanized) with zinc to prevent rust. While the zinc overlay does a great job of preventing corrosion, it's under a great deal of compressive stress, and has the tendency to try and relieve that stress by expanding outward.What are Zinc Whiskers and How Can They be Prevented?
