Metal clad plate is a composite material formed by metallurgical separation of metals with different properties at the interface using various composite technologies. Through appropriate material selection and reasonable structural design, metal clad plates can greatly improve the thermal shrinkage, strength, toughness, wear resistance, corrosion resistance, electrical properties, magnetic properties and many other properties of a single metal material, so they are widely used It is widely used in petroleum, chemical industry, shipbuilding, metallurgy, electric power, water conservancy, transportation, environmental protection, food, pharmaceutical and other industries. In addition to its structural and functional characteristics, metal composite panels can also save the use of goods and significantly reduce the cost of various equipment materials.
Common metal clad plates are: titanium-steel clad plate, copper-steel clad plate, titanium-zinc clad plate, titanium-nickel clad plate, nickel-steel clad plate, copper-aluminum clad plate, nickel-copper clad plate, etc.
Metal clad material technology can give full play to the respective advantages of component materials, complete the excellent configuration of each component material resource, save precious metal materials, and achieve performance requirements that cannot be met by a single metal. Taking stainless steel-steel clad plate for pressure vessels as an example, the basic Ordinary carbon steel (Q245R, Q345R, etc.) has good mechanical properties, and stainless steel (304, 316L, etc.) for cladding has good corrosion resistance. The two are usually welded together by blasting, and only a few millimeters are required. The high price of stainless steel saves a lot of cost, and almost does not change the various mechanical properties of the substrate. It can not only replace imports, but also has a wide range of applications, has good economic and social benefits, and is easy to obtain support and assistance in 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 performance utility, lower cost and wide application range of heterogeneous metal composite materials, the development potential of traditional metal composite materials has been improved. With the strengthening of the implementation of the national environmental protection industry policy, the application of rare metal composite materials in electric flue gas desulfurization equipment continues to grow. At the same time, the level of investment localization 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 broad space for the development of the industry. The metal clad plate is a plate with one layer of metal covered with another metal, which has achieved the effect of saving resources and reducing costs without reducing the application effect (corrosion resistance, mechanical strength, etc.).
