Abstract:
The invention relates to a method and an aluminium alloy sheet material. The method of producing aluminium alloy sheet material comprising the following steps: continuous strip casting of a sheet at a predetermined solidification rate ensuring material microstructure exhibiting primary particles having average size below 1 micrometer2, and (cold) rolling of the strip cast sheet to an appropriate gauge with optionally intermediate annealing during the cold rolling. It is an object of the present invention to provide a novel method of production of Al-alloy sheets applicable on heat exchanger sheet based components resulting in improved pitting corrosion applying (base) Al-alloy material with higher Fe-content.
