The present work deals with an experimental study on various sorts of copper was carried out with the use of an electromagnetic launching ring technique in order to select the material with a desirable property for performance of a shaped charged jet. The obtained results proved that the copper with the smallest grain size revealed the highest ductility under electromagnetic expanding ring loading conditions. The performed observations seem also to suggest that the electromagnetic expanding ring test may be applied as a tool for a choice of liner materials.
