Metal composite material is widely used in a variety of industries, but we know the preparation of composite material is less. The following outlines several methods for preparing the composite material. 
1, The domestic production of composite composites are mainly solid - liquid phase binding assay, solid white binding assay, stacked plate hot rolling method, diffusion crimping, welding method, welding hot rolling method. The most common method is a combination of solid phases explosive welding and hot rolling. Explosive welding of stainless clad steel sheet late in the development and application at home and abroad. 
2, Rolled stainless steel composite steel composite composite method is divided into hot-rolled and cold composite. This composite material complex method of high yield, high dimensional accuracy, technology and equipment is more mature, but often enhanced surface treatment and annealing treatment.
