Metal composite technology can give full play to the respective advantages of component materials, to achieve the optimal allocation of each component material resources, save precious metal materials, to achieve a single metal can not meet the performance requirements, to pressure vessel stainless steel-steel composite plate as an example, the base layer with general carbon steel (Q245R, Q345R, etc.) has good mechanical properties, multilayer stainless steel (304, 316L, etc.) has good corrosion resistance, the two are usually welded together by explosion, only a few millimeters of high-priced stainless steel, Significant cost savings are achieved and the various mechanical properties of the substrate are hardly changed. It can not only replace imports and fill the domestic gap, but also has a broad application range, 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 functionalization of the properties of heterogeneous metal composites, the low cost and wide range of applications, the development potential of traditional metal composites is improved. With the strengthening of the implementation of national environmental protection industrial policies, the application of rare metal composite materials in power flue gas desulfurization equipment continues to grow, and the degree of localization of investment in the chemical industry has been 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 a broad space for the development of the industry. Metal composite panel is a board 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 (anti-corrosion performance, mechanical strength, etc.).
