Known as a light coated graphite based electrode, Cast Iron Electrodes are used for various industrial purposes. Due to brittle nature, cast iron is used for the manufacturing processes. These are having ferro-nickel type of weld metal deposition that offers ductile characteristics along with adequate strength and machinability. Thus, without using preheat these electrodes are suitable for welding cast iron. The mentioned deposit is said to be free of any defects including cracks, porosity and provide merging colour ability with cast iron.
