The request for aluminium with enhanced properties, such as an improved resistance to intergranular corrosion for the 6xxx alloys has risen in the past years. In the past years there have been investigations on the IGC behaviour of 6xxx extrusion alloys, but no studies about the behaviour of rod are known to the authors of this paper. In this article, the IGC behaviour of 6082 rod will be investigated. The rods were produced by TRIMET in Castelsarrasin with a continuous casting and rolling process. They were subsequently, in the labs of TRIMET, homogenised, drawn with final area reduction of 53%, annealed and heat treated. The samples were than tested according to the VW PV1113 for ICG of 6XXX alloys, a test used on extruded profiles, permitting a comparison of the results. Results indicate that chemical composition and process parameters have a strong influence to the corrosion sensitivity of this material.
