Abstract: A thermal expansive aluminum guide roller includes: an aluminum guide roller base, wherein the aluminum guide roller base is coated by an irony layer, the irony layer is coated by a hard metallic layer. Preferably, the hard metallic layer is a nickel layer or a titanium layer. Aluminum is utilized because of a small density. With the light weight, inertia is small and a rotation speed can be adjusted rapidly for quickly adapting to different conditions while coating. A production method of the thermal expansive aluminum guide roller includes: a step of preparing the aluminum guide roller base, wherein the production method further includes steps of: A) preparing an irony sleeve; B) inserting the aluminum guide roller base into the irony sleeve; C) forming the irony layer; and D) forming a coating layer, wherein the irony layer is coated by a hard metallic layer.
