Abstract

The Al-6Cu-Mn alloy differs from other aluminum alloys in that it has relatively good mechanical properties at low temperatures and, therefore, can be successfully used for low-temperature structures. Unlike the duralumin-type alloys, the Al-6Cu-Mn heat-treatable alloy contains more copper (5.8 to 6.8%) and no magnesium [1]. It is similar to the USA alloy 2219. It has satisfactory weldability and mechanical properties over a wide range of temperatures: from 20 K up to 523 K, making it suitable for welded vessels for liquefied gas transportation and storage.
