The kinetics of cooling of the aluminium grade of the A5N, its alloys doped with silicon, copper, and rare-earth metals in a wide temperature range were measured. It revealed that the process of cooling of the aluminium and its alloys has a relaxation behaviour. An experimental study of the specific heat and heat transfer coefficient of these substances is carried out. According to experimental data, the temperature dependence of the heat transfer coefficient for pure metals is calculated. It is shown that the values of heat transfer coefficients of copper, aluminium, and zinc are different. To determine the heat capacity of doped alloys for each group is recommended to define the coefficient of heat transfer of the initial alloy.

Key words: aluminium A5N, cooling, specific heat capacity, coefficient of heat transfer.
