摘要

Aluminum alloy casts are widely used in industry as elements for heat exchangers. In this case, the main requirements are the thermal conductivity and the mechanical properties of the alloy. According to the Wiedemann-Franz law, the thermal conductivity of the alloy can be expressed by its electrical conductivity. The paper presents the results of the research on the effect of the heat treatment parameters on the electrical conductivity of cast aluminum alloys, type AlSi7Mg and AlSi10Mg. The aim of the work is to determine the possibilities of obtaining the electrical conductivity of an alloy, while maintaining the required level of mechanical properties. The tests include the Brinell hardness measurements and the electrical conductivity evaluation by means of the eddy current method, on samples after artificial ageing. On the basis of the studies determining a range of heat treatments, it is possible to obtain 23.5 MS/m, in the case of AlSi10Mg, and 27 MS/m, in the case of AlSi7Mg.
