SiFeCr Anode for Cathodic Protection

As the technology exploiter of SiFeCr anode in China, CORROCO manufactured the first piece of SiFeCr anode in 1981 in China. We can make taper pin connection anode, bolt connection anode, center connection anode, canisters anode to content the different requirement of the customer. In 2004, we succeed in the casting technology of CHILL MOULD. Now, we have been already one of the largest SiFeCr anode manufacturer and supplier in the world. The produced cast iron material used for anodes typically has the following properties: Chemical CompositionsWe cast the anode according to ASTM 518 or BS1591 standard, and their chemical composition are listed in the following table.
