TY - JOUR N2 - The aim of this publication is to present practical application of the R. Kolman’s quality rating method used in the evaluation of aluminium alloys. The results of studies of the mechanical and physical properties of the three selected test materials are discussed. To find the best material, the quality level of each of the tested materials was assessed using quality ratings proposed by R. Kolman. The results of the conducted analysis have proved that the best material was an AKII MM alloy, i.e. a casting AK11 aluminium alloy from the 4XXX series.
