Producers list, high-temperature alloys

Table I lists the mechanical properties of thermally hardened alloys of the duraluminum type (Al-Cu-Mg), as well as the Al-Zn-Mg-Cu alloys. A temperature decrease to 20 K increases the ultimate strength by 25 to 30%. The yield stress continuously increases as the temperature decreases. The relative elongation behaves in different ways in some alloys, it is practically constant, while in alloy V96 it is reduced by almost a factor of 5. Thus, hardening of alloys, such as V95 and V96, by thermal treatment produces materials with a sufficiently high level of strength, but losses in plasticity are inevitable. This is a significant limitation of their application in cryogenic equipment.
