摘要： An object of the present invention is to provide a 6000-series aluminum alloy material for a high-pressure gas container which has both of resistance to hydrogen embrittlement and mechanical properties. In the aluminum alloy material for a high-pressure gas container, the contents of Fe, Mn and Cu fall within narrower ranges than the standard composition of AA6066 alloy. The aluminum alloy material is produced to have a structure in which a predetermined amount of fine dispersed particles are dispersed therein and coarse crystallized materials are small, and therefore strength and resistance to hydrogen embrittlement are improved, which are required for a high-pressure gas container.
