Intravascular devices, systems, and methods are disclosed. In some instances, the intravascular device is a guide wire having a core wire formed of multiple materials. For example, a sensing guide wire is provided that includes a core member having an inner section and an outer section surrounding the inner section, wherein the inner section is formed of a first material and the outer section is formed of a second material that is different than the first material and a sensing element coupled to a distal portion of the core member. Methods of making, manufacturing, and/or assembling such intravascular devices and associated systems are also provided.
