Sažetak
Extruded products made from 2XXX aluminum alloys nowadays are used for various applications. That is because of fact that this series of aluminum alloys have many specific features related to their excellent mechanical properties. One of the most common semi product made from these alloys are rounded extruded rods. They are widely use as a row material in automated machining processes. The roundness of these rods, among the other factors, is required within narrow tolerances. Production of rods from this aluminum alloys is connected with several mutually connected metal forming and thermal treatment processes. In order to increase production of these semi product many extruders prefer to use multi holes extrusion dies. The number of holes depends on rods diameter and available container of the extrusion press. This paper describe the procedure for manufacturing rods from alloys 2007 T3 and 2011 both in T3 and T8 tempers. For this production, a solid die with 2 holes was designed and manufactured. Extrusion was performed on horizontal 25 MN extrusion press. Rods from 2007 were cold drowned to final dimension of 28 mm and those from alloy 2011 to diameter of 27 mm. All extruded rods were thermally treated to appropriate temper. Both dimensional and mechanical properties after each stage were analyzed. Result of these investigations could be useful for industrial practice.
