Aluminium castings are treated thermally to achieve better mechanical properties. For this purpose parameters of the thermal treatment process and stable operation of the furnace are of great importance.
After thermal treatment test tubes are manufactured to measure mechanical properties in accordance with the control procedure for individual pieces. Test samples are labelled in accordance with the stadard operation procedure (SOP) – sampling, sample labelling and result entering after thermal treatment.
Most frequently thermal treatment T6 is performed to achieve the best mechanical properties of individual alloys. Considering customers' requirements thermal treatment according to procedure T4, T5 could also be performed.
