- Grinm Metal Composites (Beijing) Technology Co., Ltd. is a China-based advanced materials enterprise primarily engaged in the research, development, manufacture, and distribution of metal matrix composites, bimetal composite materials, and specialty nonferrous metal alloy products. The company operates through three core product segments: Metal Matrix Composites, Bimetal Composites, and Specialty Nonferrous Alloys. Its comprehensive product portfolio includes aluminum matrix composites, comprising particle-reinforced aluminum matrix structural components and forgings for fixed-wing aircraft and helicopters, high-efficiency heat-dissipating packaging materials for military and power electronics, lightweight composite battery compartments for consumer electronics, and spherical alloy powders for metal additive manufacturing; bimetal composite materials, featuring hot isostatic pressing titanium-aluminum bimetal middle frames for high-end smartphones, titanium-aluminum laminated composite sheets for aerospace structures, and customized multi-metal layered components; and specialty nonferrous alloys, encompassing high-strength and high-toughness aluminum alloys, spacecraft groove heat pipe profiles, high-nickel cupronickel, manganin precision resistance alloys, and specialty corrosion-resistant alloy tubing used in smart metering, nuclear energy, and precision instrumentation. In addition, the company provides specialized technical services, including nonferrous powder metallurgy processing, hot isostatic pressing, precision casting, plastic deformation processing, and advanced mechanical machining. Grinm Metal Composites caters primarily to customers in the aerospace, defense, consumer electronics and smart terminals, power grid, nuclear, and automotive sectors throughout China and select global markets. Founded in 2019 and headquartered in Beijing, China, the company operates as a specialized advanced material subsidiary of China GRINM Group Co., Ltd. under the State-owned Assets Supervision and Administration Commission of the State Council. In recent developments, Grinm Metal Composites completed its initial public offering on the Sci-Tech Innovation Board of the Shanghai Stock Exchange under the ticker symbol 688811 in April 2026 to finance the expansion of its advanced composite materials production bases and engineering research centers. The company has also scaled commercial mass production of its proprietary titanium-aluminum bimetallic frames for flagship smart terminal manufacturers and deepened the deployment of its particle-reinforced aluminum matrix composites across next-generation aviation programs, commercial space applications, and high-power electronic thermal management systems.
