The EN AW 2011 alloy is one of the heat-hardening alloy that, after appropriate thermomechanical treatments, achieves high strength properties due to the processes of precipitation hardening. The main alloying element of this alloy is a copper whit a mass content of 5-6 %. The addition of lead in a mass content between 0,2-0,6 % enables good machining of automatic machine tools. The most common products are tubs, rods and profiles. The purpose of the diploma work is to compare the mechanical and microstructural properties of extruded bars dimensions 35 mm, alloy EN AW 2011, which were manufactured by three different technological procedures. In the first process, the rods were quenched on a press and precipitation hardened, in the second process the rods were solution annealed and quenched in a salt bath, followed by precipitation hardening. The third technological process is a combination of both, which means that the rods were first quenched on a press, then solution anneled and quenched in a salt bath. The process was completed whit precipitation hardening. The input raw material is a pole measuring 282 mm in length 6900 mm, which is turned to a diameter of 275 mm in the turning centre located in the PP Cevarna plant and cut to a length of 1400 mm. We also cut a disk from the pole on which we did a microstructure analysis on the edge in the middle and on the d/4. We also performed a chemical analysis on the disk and an analysis of the mechanical properties. The prepared round was then heated in an induction furnace and in one case it was quenched, and in the other case, extrusion was performed on 35 MN indirect press immediately after heating. We use three cavities flat tool. At incision, samples were taken from all three vessels in the T1 and T1A states. This was follows by solution annealing and quenching in salt bath at the temperature of 520 °C ± 10 °C for a period of 300 s follows by precipitation hardening, so that we reached the T6 state and the new T6A state. The T5A state is achieved by precipitation hardening the material in the T1A state after extrusion. Precipitation hardening was carried out for 4 hours at a temperature of 170 °C and 12 hours at the temperature of 190 °C. We also performed a chemical analysis, mechanical and microstructural properties on the rods.
