Recommented for brackish water and sea water, HYDRAL 2C is an aluminium alloy containing magnesium which offers a lot of advantage over Zinc.
-Grater efficiency thanks to an anodic production capacity 3.3 times higher (800 Ah/kg for zinc, 2650 Ah/kg for HYDRAL 2C)
-Greater environmental friendliness thanks to a non-polluting deposit
-Lightness, for the same volume HYDRAL 2C is 2.4 times lighter than zinc
