The thermal diffusivity ( a ), the thermal coefficient of linear expansion (α), the isobaric heat capacity ( c p ) and the fusion enthalpy (ΔH) of aluminum-magnesium alloy AMg3 were investigated by laser flash method, dilatometric method and method of differential scanning calorimetry in the temperature range of 300–773…1000 K. The thermal conductivity (λ) has been calculated from the measurement results. The estimated errors of the obtained data were 2–5%, 3–5%, 2–3% and (1.5–2.0)⋅10 -7 K -1 for a, λ, c p and α, respectively. Approximation equations and a table of reference values for the temperature dependence of the studied properties have been obtained.
