    engine blocks include Grey Cast Iron‚ aluminum and Compacted Graphite Iron (CGI). In the early years of building engine blocks‚ grey cast iron was the only material used. The process of using alloys was non-existent and aluminum was a new material which few people were familiar with. At the time‚ however‚ grey cast iron worked very well. The carbon‚ present as flakes of graphite‚ in grey cast iron gives the material good resistance to wear and also provides good corrosion resistance and lubrication
