The effect of heat treatment on the electrical resistance and thermal conductivity of synthetic grey cast iron is considered. The mechanism of forming phases and structural components of cast iron depending on the mode of heat treatment (HT) is presented. Experimental dependences of electrical resistance and thermal conductivity on cast iron composition and heat treatment parameters are found out. Recommendations are proposed that make it possible to select one or another alloy for real products with the required set of electrophysical characteristics. The importance of the presented studies is stressed, the results of which will allow replacing traditional expensive high-resistance materials with less expensive gray cast iron.
