Yantai Wanlong Vacuum Metallurgy Co., Ltd. was established in 2002. It occupies a site area of 69,000 square meters with a building area of 42,000 square meters. The company has a registered capital of RMB 80.4 million and employs over 350 staff members. The company is a National High-Tech Enterprise, a key “Little Giant” enterprise supported by the Ministry of Industry and Information Technology for its specialization, refinement, uniqueness, and innovation. It is also recognized as a Shandong Provincial Manufacturing Single Champion Enterprise, a Shandong Provincial Innovative Pilot Enterprise, a Chain Leader in Shandong's Advanced Copper Alloy Industry Chain, a Shandong Provincial Technological Innovation Demonstration Enterprise, one of Shandong's Top 50 New Materials Leading Enterprises, and among Shandong's Top 100 Private Enterprises with Innovation Potential. and among Shandong's Top 100 Private Enterprises with Innovation Potential. As China's first enterprise specializing in “special copper” products, its core business involves developing and manufacturing high-performance specialty copper alloy materials and products using proprietary processes and specialized equipment. These serve industries including high-speed rail, nuclear power, nuclear fusion, aerospace, metallurgy, machinery, offshore engineering, automotive, electronics, and power generation.

　　The company operates provincial-level R&D platforms including the Shandong Provincial Enterprise Technology Center, Shandong Provincial Engineering Research Center for Integrated Melting and Casting Technology of High-Performance Special Copper Alloy Materials, Shandong Provincial Industrial Design Center, and Shandong Provincial One-Enterprise-One-Technology R&D Center. It currently holds 78 valid patents and It has led or participated in formulating seven industry standards. The company has obtained certifications for ISO/TS 22163 (International Rail Transit Industry System Standard), ISO 9001 (Quality Management System), ISO 14001 (Environmental Management System), ISO 45001 (Occupational Health and Safety Management System), and GB/T 29490 (Intellectual Property Management System). Its high-speed rail chromium-zirconium copper contact wires and suspension cables have passed national-level new technology (product) evaluations. Won first place in Shandong Province and eighth place nationally in the Fifth China Innovation and Entrepreneurship Competition; received the Gold Award in the Fifth China Advanced Technology Transformation and Application Competition in 2023; undertook one Ministry of Industry and Information Technology Industrial Strengthening and Foundation Project in 2017. Awarded two Shandong Provincial Science and Technology Progress Awards, one Second Prize in the 2022 China Nonferrous Metals Industry Science and Technology Award, and five Yantai Municipal Science and Technology Progress Awards.

　　High-performance specialty copper alloys, as critical foundational materials, face production constraints due to process and equipment limitations. Certain high-end copper alloys cannot be manufactured domestically, severely hindering transformation and upgrading in related fields. Wanlong Vacuum independently developed core processes and manufactured key equipment, resolving multiple “bottleneck” constraints in relevant sectors.
