6026 aluminium bars
This innovative alloy has been conceived and developed in Eural Gnutti SpA’s research laboratories, in order to meet the most recent standards for the protection of the environment. It is particularly suitable for being machined on high speed automatic lathes. It has good resistance to corrosion, medium-high mechanical properties, good suitability for decorative and industrial hard anodizing. It is also used for hot forging purposes. Eural 6026 alloy does not contain tin (Sn) which, as it has been proved, causes weakness and cracking of the machined parts when submitted to stress and high temperature. It is an alternative to 6061, 6082, 6064A, 6262, and 6012 alloys.
