Using the full potential of each component material's advantages, metal composite technology can fulfill performance criteria that cannot be met by a single metal while realizing the best use of component material resources. It can not only fill in domestic gaps and replace imports, but it also offers a wide range of uses, positive economic and social effects, and simple access to all forms of assistance. 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 functionalization and lower cost of heterogeneous metal composites, and a wide range of applications, the development potential of traditional metal composites has been improved. With the strengthening of the implementation of national environmental protection industry policies, the application of rare metal composite materials in electric flue gas desulfurization equipment continues to grow. At the same time, the degree of localization of investment in the chemical industry has been greatly accelerated, which also provides good development opportunities for the development of rare metal materials.
The support of national industrial policies, high technical barriers, and the demand for industrial upgrading provides a broad space for the development of the industry. The metal composite board, which has the function of conserving resources and cutting prices without diminishing the usage effect, is a board coated with another metal on one layer of metal (anti-corrosion performance, mechanical strength, etc.).
With the rapid development of the national economy and the emergence of various new technologies and new industries, the demand for engineering materials with various properties is becoming more and more extensive. A single metal material is either limited by natural resources, or due to insufficient comprehensive performance, its application fields are greatly limited. In this case, the development, production, and application of composite materials are increasingly showing their important status.
In recent years, due to the continuous emergence of new processes and technologies, the development and application of metal composite panels have been greatly expanded, and the application fields of materials have been continuously extended.
In 1956, the United States took the lead in proposing a three-step process of metal lamination, namely: surface treatment-rolling cladding-multilayer metal cladding theory and technology, layered metal clad plate production technology, and new process annealing strengthening treatment. Metal room temperature solid phase recombination has been developed rapidly.
The former Soviet Union's research on laminated composite materials began in the 1930s, mainly using rolling methods, casting methods, explosion methods, etc. to produce composite materials of metals and alloys such as aluminum, titanium, steel, etc., especially in cold rolling composites. The research is more in-depth.
Developed countries such as Britain, France, and Germany also have a considerable level of research on composite materials. Among them, the University of Birmingham in the United Kingdom conducted relatively systematic research on solid-phase composites in the 1950s and 1960s and achieved many results.
At present, metal composite materials are widely used in these countries. Japan's research on composite materials started late, but its development is very rapid. In recent years, Japan has become one of the countries engaged in the most research on metal composites. After the 1990s, many achievements have been made in the composite research of stainless steel and aluminum, and a number of patents have been applied for, especially remarkable research results have been achieved in the aspects of step heating composite and warm rolling composite.
