This utility model discloses a composite material rod-tube, including an alloy component in the shape of a cylinder with an axially penetrating hollow cylindrical cavity. An iron rod is coaxially disposed within the cylindrical cavity, and a circular boss is formed at each end of the iron rod. An annular welding space is formed between the outer peripheral wall of each circular boss and the corresponding end face of the alloy component. The annular welding space is used to accommodate solder to achieve a fixed connection between the alloy component and the iron rod. By coaxially embedding the iron rod within the alloy component, the two work together to form an annular welding space, providing a carrier for the solder. During brazing, the molten solder fully wets the annular welding space under capillary action. After the solder cools, it forms a positioning and connection strengthening structure, rigidly connecting the alloy component and the iron rod. This effectively avoids the interlayer slippage problem that occurs when the aluminum alloy-clad iron rod is subjected to long-term high-frequency reciprocating motion, meeting the structural strength requirements of printer / copier components under high-frequency motion scenarios.
