Another thing to consider though, Morgoth was vulnerable to Fingolfin's sword Ringil suffering a number of wounds from it and crying out (making his own armies quail each time) as well as receiving a wound from the eagle who recovered Fingolfin's body. If a Valar could suffer wounds from a 'conventional' weapon like a sword I find it impossible to believe that a mere Balrog would be invulnerable.
