Aldrey

The word Aldrey (E- AlMgSi ) describes an aluminum alloy with an admixture of 0.5% magnesium and 0.5% silicon .

The tensile strength is higher than with pure aluminum, but decreases permanently at over 100 ° C. The material has good electrical conductivity and is more resistant to corrosion than pure aluminum. Therefore it is often used as a wire drawn on a property for the manufacture of overhead lines .
