Approximately 1.7A (1A\$\cdot\sqrt{3}\$), all other things being equal, and assuming a \$\Delta{T}\$ of 5°C due to ripple current for 105°C rated capacitor with a 105°C Ta and \$\Delta{T}\$ of 15°C for the 105°C rated capacitor with an 85°C Ta. Those are just typical values, the manufacturer may be able to advise for a given capacitor model and ratings.

Keep in mind that the life span of aan aluminum electrolytic capacitor at the maximum rated temperature and ripple current is usually unacceptable for real applications (like a few thousand hours only), so you typically don't want to be anywhere near those limits under normal operating conditions.
