A: Westwin Elements is scaling America's only Class 1 nickel refinery. Using the nickel carbonyl process, Westwin produces high-purity (≥99.9%) nickel powder and briquettes for defense, aerospace advanced manufacturing, and other critical industries. This domestic capacity will reduce U.S. reliance on foreign refining and strengthen national security.

A: Westwin operates a demonstration plant in Lawton–Fort Sill, Oklahoma. Since commissioning in December 2024, the facility produced the first reported U.S.-made nickel powder from mixed hydroxide precipitate using the carbonyl process. Westwin has since completed multiple successful production campaigns, establishing a clear path toward commercial production. The company will soon announce the site of its commercial refinery.

A: Class 1 nickel is refined nickel with a purity of at least 99.8%. Its strength, heat resistance, and corrosion resistance make it essential to defense systems, aerospace alloys, batteries, and other advanced applications. Westwin’s carbonyl process converts nickel-bearing feedstocks into high-purity nickel powder and briquettes suitable for critical uses.

A: Carbonyl refining is a form of vapor metallurgy which uses controlled changes in pressure and temperature to separate nickel from other elements and refine it into high-purity powder and briquettes. First commercialized in 1902, the process has more than a century of industrial use.  Westwin selected carbonyl refining for its ability to process a range of nickel-bearing feedstocks, recover and reuse process gases, limit waste, and produce nickel with a purity of 99.9% or greater. Westwin’s team brings nearly 250 years of combined carbonyl processing experience and approximately 130 additional years of engineering experience.

A: Nickel is essential to jet engines, naval systems, armor, munitions, and other defense applications. It also supports batteries, stainless steel, and advanced manufacturing. The U.S. government classifies nickel as a critical mineral, yet the United States lacks domestic commercial Class 1 nickel refining capacity and relies fully on foreign supply chains. Restoring this capability at home would reduce exposure to supply disruptions and foreign control while strengthening defense readiness and American industry.

A: The United States imports the Class 1 nickel used by its manufacturers, with major sources of refined nickel including Canada, Norway, and Australia. Although several of these countries are close U.S. allies, America still lacks commercial-scale Class 1 nickel refining capacity of its own. This leaves an essential industrial and defense material exposed to foreign production, trade disruptions, and global competition.

A: Westwin plans to scale America’s only nickel refinery through a phased expansion. After demonstrating its carbonyl refining technology at its Lawton-Fort Sill facility, Westwin is advancing the first phase of commercial development. The company plans to expand production in stages, reaching 68,000 tonnes per annum by 2031.

A: Class 1 nickel contains at least 99.8% nickel and includes products such as powder, briquettes, cathodes, and pellets. Its high purity makes it suitable for demanding applications, including aerospace and defense alloys, batteries, specialty chemicals, and advanced manufacturing. Class 2 nickel contains less than 99.8% nickel and includes products such as ferronickel and nickel pig iron. It is used primarily to produce stainless steel. Although both classes serve important markets, Class 2 nickel cannot directly replace Class 1 nickel in applications with strict purity and performance requirements.

A: Westwin manages nickel carbonyl within a sealed, closed-loop system designed to prevent worker and environmental exposure. Multiple layers of protection, including continuous monitoring, automated shutdown systems, engineering controls, operating procedures, and specialized workforce training, support safe operations. Westwin’s team applies decades of commercial carbonyl experience and established industrial safety practices to the design and operation of its facilities.

A: Westwin’s carbonyl process operates at lower temperatures than conventional metallurgy methods and recovers and reuses process gases within a closed-loop system. This approach can reduce energy use, air emissions, water consumption, and waste compared with many traditional nickel-refining methods. Westwin designs its facilities to meet applicable environmental standards and manages all residual materials through approved treatment, recycling, or disposal methods.

A: The United States produces a limited amount of nickel-bearing material, but it lacks commercial-scale capacity to refine that material into finished Class 1 nickel. Domestic nickel concentrates generally leave the country for further processing, while American manufacturers rely on imported refined nickel. Westwin is working to close this gap by establishing domestic production of high-purity nickel powder and briquettes.

A: No. Westwin is a critical mineral refining company. The company uses the carbonyl process to convert nickel-bearing feedstocks into high-purity Class 1 nickel powder and briquettes. This refining capability fills a critical gap between upstream mineral production and the American industries that rely on finished nickel products.
