Hydrofluoric acid (HF) is technically a weak acid, i.e., when hydrogen fluoride is solved in water, it dissociates incompletely and not all of its hydrogens are released in the solution.

Though such weak acids are generally not as corrosive as strong acids, that is not true for HF: it is extremely corrosive and can dissolve all metals but iridium. It's well known for its capability to solve glass, too.
