An Old Material Meets a New Challenge - Integral Cast Iron Hub and Disc Development

Cast iron has been used as an engineering material for 2000 years. The concept of an integral hub is not new to the automotive engineer since it dates back at least 40 years. For economic considerations, the use of cast iron has been merged with the concept of an integral hub and disc for passenger car usage. This paper discusses the various problems involved in the utilization of cast iron and includes details of various tests and their results necessary to prove out this design.
