This study presents the results of testing the shape index, number of graphite precipitations, and longitudinal ultrasound wave velocity with wedge castings used for production of samples for the assessment of mechanical characteristics. To differentiate values of the parameters, the castings were made at the same time as the production castings. The data obtained were used to establish the relationship between the ultrasonic wave velocity cL, the shape index SS and the number of graphite precipitation NA.
