The invention relates to a production method for composite materials, in particular to a production method for a multi-metal composite material adopting rolling-annealing connection. The production method includes the following steps of (1) raw material preparation; (2) surface pretreatment; (3) clad rolling and continuous annealing; (4) finish rolling; (5) cover annealing; (6) flattening; (7) shearing; (8) inspection; and (9) packaging and warehousing. The one-time rolling-forming rolling process is adopted by the method, continuous annealing is directly carried out, strips can be preheated by fully utilizing waste heat generated under large deformation during one-time rolling, the adverse influence caused by heat stress generated by quick strip heating on the strips is greatly lowered, and a large quantity of energy can be saved; and through recovery of metal crystals and mutual diffusion of atoms in continuous annealing, composite surfaces of two kinds of metal are combined as firm as whole metal through atom combination. The production method has the characteristics of high production efficiency, low production cost, easy operation, and high product quality.
