AB This paper presents some analysis of color metallography in the identification new structures of aluminium alloys. For experimental purposes aluminium alloy from the group hypereutectic AlSi7Mg 0,3 silumins was used. Alloy and modified using calcium in the form of master alloy AlCa10. The master alloy AlCa10 in the analyzed alloys added to improve the technological properties af alumium alloys, especially fluidity and machinability while maintaining sufficient corrosion resistance of the alloy. The analysis and evaluation of individual structural components are used method of color etching. The analyzed alloy was also subjected to the method of the black and with contrast what, but not of this paper subject. The application of color metallography is possible to differentiate and identify the presence of the intermetallic particles with different chemical composition.
