Metal composite technology can give full play to the respective advantages of component materials, realize the optimal allocation of material resources of each component, save precious metal materials, and achieve the performance requirements that cannot be met by a single metal. Take the stainless-steel composite plate used for pressure vessels as an example, the ordinary carbon steel (Q245R, Q345R, etc.) used for the base layer has good mechanical properties, and the stainless steel (304316L, etc.) used for the cladding has good corrosion resistance, They are usually explosive welded together, requiring only a few millimeters of high price stainless steel, which greatly saves costs and hardly changes the various mechanical properties of the substrate. It can not only replace imports and fill the domestic gap, but also has a wide range of applications, has good economic and social benefits, and is easy to obtain support and help from all aspects. For example, the development of stainless steel composite materials has always been a high-tech project actively supported and advocated by the National Development and Reform Commission and the Ministry of Science and Technology.
Due to the functional properties, low cost and wide range of application of heterogeneous metal composites, the development potential of traditional metal composites has been improved. With the strengthening of the implementation of the national environmental protection industrial policy, the application of rare metal composite materials in power flue gas desulfurization equipment continues to grow, and the localization of investment in the chemical industry has greatly accelerated, which also provides a good development opportunity for the development of rare metal materials.
The support of national industrial policies, high technical barriers and the demand for industrial upgrading provide broad space for the development of the industry. Metal composite plate is a plate covered with another metal on one layer of metal, which has achieved the effect of saving resources and reducing costs without reducing the use effect (corrosion resistance, mechanical strength, etc.).
