SCHIEDAM, December 2017 ~ VETUS has expanded its range of sacrificial anodes with 27 new models for various vessels. They include 16 models for steel hulls, 6 suitable for a shaft and 5 suitable for a rudder.
All vessels, especially steel or aluminum-hulled ones, require anodes to protect underwater metal parts. VETUS’ new zinc anodes meet the highest U.S. Mil. -A-18001 K. specifications and come in weights of 0.68 to 3 kilos. The aluminum anodes are made from an aluminum-indium-zinc alloy Mil. -A-24779 (SH) and weigh between 0,36 to 1,45 kilos. There is a choice of rectangular or tear-drop shapes to match the flowing lines of the boat.
For the shaft and rudder, VETUS offers anodes in zinc weighing 0.25 to 0.71 kilos and 0.08 to 1.5 kilos respectively. VETUS recommends aluminum anodes for vessels cruising mostly on fresh waters. Aluminum has a greater difference of potential with other metals than zinc. This is very important as fresh water provides a higher electrical resistance than salt water. For salt or brackish water cruising, VETUS recommends zinc anodes. Aluminum anodes work well in salt water but don’t last as long. For weld-on anodes: galvanized steel tags allow easy installation.
