General rule of thumb. 1.5*thickness of metal (inches)
If you have to come close to the minimum, consider the direction of the grain and the heat treatment of the metal. It is always better to bend against the grain (perpendicular) than with the grain. And never bend tighter than in the -O (Original) condition.
