The thermal conductivity of aluminum alloy is more than four times higher, than that of carbon steels. They begin to melt at a much lower temperature, than steel. The melting point of pure aluminum is about 660 ° C, and aluminum alloys depending on the degree of alloying begin to melt at lower temperatures, for example, at 515 ° C for alloy 2021
30/3/2021 As described separay [], there are many properties of aluminum alloys used to determine their thermal stability.

The usage of Aluminium was rising from 3% to 13% in the last 40 years. The challenges to apply Aluminium are created by the high thermal conductivity, the melting points of the oxydes and the solubility for Hydrogen. In alloys additionally so-called hot cracking occurs due to the solidification kinetics. Table
