In paper it is presented thin wall ductile iron casting (TWDI) as a substitute of aluminium alloy casting. Upper control arm made of ductile iron with wall thickness ranging from 2 - 3.7 mm was produced by inmold process. Structure, mechanical properties and computer simulations were investigated. Structural analysis of TWDI shows pearlitic-ferritic matrix free from chills and porosity. Mechanical testing disclose superior ultimate tensile strength (Rm), yield strength (Rp0,2) and slightly lower elongation (E) of TWDI in comparison with forged control arm made of aluminium alloy (6061-T6). Moreover results of computer simulation of static loading for tested control arms are presented. Analysis show that the light-weight ductile iron casting can be loaded to similar working conditions as the forged Al alloy without any potential failures.
