Aluminum alloys are one of the most popular casting materials. Their enormous popularity due to a wide set of desired material properties such as high strength properties, low thermal expansion coefficient, high thermal and electrical conductivity, very good casting properties, including castability. The most common group of cast aluminum alloys are silumins, where the main alloy addition is silicon. Al-Si alloys are mainly used in the transport industry and construction applications. Another area of applications using this group of materials is the electrical and power engineering industry, where the crucial meaning has the correlation of two types of properties: electrical and mechanical. This paper presents the influence of alloying elements on the electrical properties and mechanical properties of materials undergoing heat treatment. Heat treatment include solution heat treatment and next aging or overaging. Electrical properties represents the electrical conductivity tested by eddy current method. Mechanical properties are in turn represented by the results of measurements of Brinell hardness. Tests include three alloys belong to hypoeutectic silumins group with silicon content in the range of 4,5 to 7 wt%. Si.
