Methods and apparatus for positioning a non-expandable liner hanger in a wellbore. A liner is coupled to the liner hanger, wherein the liner hanger comprises: a conduit body; and a reactive metal sealing element disposed on the conduit body, wherein the reactive metal sealing element comprises a reactive metal having a first volume. An example method includes contacting the reactive metal with a fluid that reacts with the reactive metal to produce a reaction product having a second volume greater than the first volume; and contacting a surface adjacent to the reactive metal sealing element with the reaction product to form a seal against the surface and to anchor the liner hanger from the surface, wherein anchoring the liner hanger to the surface suspends the liner in the wellbore.
