The thermal analysis is a test process for monitoring the quality of aluminium melts.
By systematically adding certain alloying elements it is also possible to influence the quality characteristics of the melt.
The cooling pattern of different aluminium alloys provides information on the formation of their structure with
regard to grain refinement (GF) and modification (M). The grain refinement describes the size of the grains while the modification
refers to the even distribution of silicon in the structure of the metal. Both these factors, GF and M provide an important
indication of the mechanical characteristics and properties which the finished casting may be expected to have.
The thermal analysis makes it possible to achieve a consistently high melt quality while effectively reducing the reject rate.
