MACH casting anode products list

High silicon cast iron anode was first used in the United States. It was only used in laboratory at first. By the early 1980s, this kind of anode began to be widely used in industrial production. The 14.5% silicon-containing cast iron anode was found to be prone to corrosion in seawater, so chromium was added to the anode in order to reduce the corrosion rate of the original anode.
