The invention relates to a multi-function hammer capable of filing ferro-aluminum. The multi-function hammer capable of filing the ferro-aluminum comprises a hammer body, a striking head, a nail nipping angle and a handle. Linear crossed tooth threads for filing iron are arranged on the left plane of an iron block of the hammer body and serve as an iron filing face. Arc tooth threads for filing aluminum are arranged on the right plane of the hammer body and serve as an aluminum filing face. The handle is made of rigid wood and is inserted into one end of the hammer body. When the multi-function hammer is used, the multi-function hammer capable of filing the ferro-aluminum can serve as a knocking tool and the iron filing face can serve as an iron filing product. The aluminum filing face can serve as an aluminum filing product. A nail which is bent by being knocked or not used any more can be tilted in a nail nipping angle V-shaped groove of the upper end of the hammer body. As the size of the iron block of the hammer body is large, inertia of the iron block is large when the iron block is used. Thus, the striking head of the lower end of the hammer body can knock an article with effort.
