#Composite material#Metal matrix composite (MMC) is a composite material obtained by joining a metal and its alloys with one or more metallic or non-metallic reinforcing materials. Conventional metal matrix composite materials include copper MMC, aluminum alloy MMC, etc., and the reinforcing materials include carbon fiber, silicon carbide, aluminum oxide, etc., and the main production technologies used include liquid metal infiltration, powder metallurgy, casting and deposition technology. , etc. Currently, metal matrix composites are mainly used in the automotive and transportation, electrical and electronics, aerospace and defense industries, as well as in industry.

In terms of production technology, the current production technology of powder metallurgy has the advantages of hot isostatic pressing or sintering temperature below the melting temperature of metal, low requirements for reinforcing materials, and free customization of metal powder and reinforcing materials according to the performance requirements of metal composite materials. Powder metallurgy production process has many advantages and reasonable cost, so the market demand is high. At present, powder metallurgy production technology is mainly used to reinforce continuous and long-fiber materials.

In terms of applications, metal matrix composites are currently widely used in automotive and transportation, electrical and electronics, aerospace and defense, industry and various other fields. With the development of light automotive industry, metal matrix composite materials are used to make automobile parts. With the steady growth of automobile production and sales, the market demand for metal matrix composite materials will increase in the future.

Among the many metal matrix composite materials, silicon carbide is currently the largest market segment of the global metal matrix composite material market in the field of reinforcing materials, and has a strong demand for applications in electrical and electronic, automotive and other fields. In terms of the development of the metal matrix composite industry, future superalloys are the fastest growing type of matrix on the market. The superalloyed metal has heat resistance and wear resistance, high strength, thermal shock resistance, electrical and thermal conductivity, etc. It is used as a refractory material for industrial tool manufacturing, and has good development prospects in the future.

According to the "2020-2024 China Metal Matrix Composite Materials Comprehensive Market Status Report" released by Xinsijie Industry Research Center, in terms of global competitive market, North America's manufacturing industry is relatively mature, leading technology, especially in manufacturing aviation and aerospace components, the development is relatively mature, and the demand for metal matrix composite materials is relatively high. This is the largest MMC market in the world. In terms of production, the current global major manufacturers of metal matrix composites mainly include Materialon Corporation, 3M and CPS Technologies Corporation.

Metal matrix composites are high-performance materials that are mainly used in automotive, aerospace and other fields. In the future, with the rapid advancement of light vehicles, the market demand for metal matrix composites will continue. get up. In terms of production, the metal matrix composite material production technology threshold is relatively high, there are few large-scale metal matrix composite material manufacturers at home and abroad, there is an imbalance between market demand and supply, and there is a lot of room for development in the industry.
