To break through current limitations of fracture splitting materials for connecting rods, a bimetallic compound as a fracture splitting material was studied. The bimetallic sample was produced by investment casting, and interface performance tests and splitting tests were conducted. At a casting temperature of 1600 °C for 0.25 wt. % C cast carbon steel, the preheating temperature of T10A was 500 °C, and the thickness of T10A was in the range of 2–3 mm. The 0.25 wt. % C cast carbon steel and T10A were fully combined in the interface. The appearance of the fracture zone was a flat cleavage fracture, which would facilitate meshing of the cracked surface if the specimen were assembled and improve the quality of fracture splitting.
