What Niobium Tech does

Niobium Tech (doing-business-as of CBMM – Companhia Brasileira de Metalurgia e Mineração) is a privately held Brazilian mining and metallurgy company headquartered in Araxá, Minas Gerais. Founded in 1955, CBMM is the global leader in niobium production and commercialization, extracting and processing niobium from Brazilian deposits and serving more than 500 industrial customers in over 50 countries via wholly-owned subsidiaries in China, the Netherlands, Switzerland, and the United States.

The company's product portfolio centers on three technology platforms: (1) NBXCELER™, a proprietary family of niobium oxide materials (sub-grades 2X2, 2HY4, 2T05, 1T05, 1H2, 1T15) engineered for ultra-fast-charging lithium-ion batteries, supercapacitors, and battery backup systems; (2) niobium microalloyed steels that improve strength, toughness, weldability, and corrosion resistance for construction, automotive, and structural applications; and (3) nanocrystalline soft magnetic materials (Fe-Si-B-Cu-Nb alloys) used in EV power electronics, current transformers, and filtering. Supporting these offerings is the Niobium Hub content platform with 628+ technical resources and a registered-user Niobium Technical Library.

CBMM operates a sales-led B2B go-to-market, generating revenue through direct industrial sales of ferroniobium, niobium oxides, and specialized niobium-based materials, complemented by technical consultation and application engineering. Pricing is quote-based and not publicly disclosed. Customers span automotive and mobility OEMs, steel and alloy producers, battery manufacturers (Toshiba, Echion, Nyobolt, Skeleton, Acbel), construction and infrastructure firms, and emerging data center infrastructure buyers, with active co-development partnerships including Echion Technologies, Nano One, JFE Steel, and Innolectric AG.

Emerging players

• Nano One Materials: Canadian cathode materials innovator with a co-development agreement with CBMM for niobium-based cathode coatings. Comparable as a downstream technology partner targeting next-generation Li-ion chemistries using CBMM's niobium inputs.
• Echion Technologies: UK-based developer of XNO® niobium-based anode materials for Li-ion batteries. While CBMM is an investor and partner, Echion is also a downstream competitor developing competing fast-charge battery chemistries that depend on CBMM's niobium feedstock.
• Skeleton Technologies: European supercapacitor and 'SuperBattery' developer using niobium-based chemistry for data center BBU and high-power applications. Overlaps with CBMM's NBXCELER™ energy-storage value proposition and is both partner and downstream customer.
• Toshiba (SCiB™ / SCiB™Nb): Toshiba's SCiB™ fast-charging lithium-ion battery line integrates niobium titanium oxide (NTO) anodes via CBMM partnership. Comparable as a downstream customer/partner pushing niobium-based batteries into mobility and industrial applications.

Broad incumbents

• ArcelorMittal: World's largest steel producer and a significant indirect customer for ferroniobium through its automotive and high-strength steel programs. Comparable as a downstream consumer shaping niobium demand intensity, with overlapping focus on lightweighting and decarbonized steel.
• Proterial (formerly Hitachi Metals): Japanese specialty materials producer of FINEMET® nanocrystalline soft magnetic ribbon used in power electronics. Directly comparable to CBMM's nanocrystalline soft magnetic materials line, with deeper incumbency in EV chargers, transformers, and inductors.
• VACUUMSCHMELZE (VAC): European manufacturer of advanced magnetic materials, including nanocrystalline and amorphous alloys, serving power electronics, EV charging, and energy applications. Comparable to CBMM's nanocrystalline soft magnetic business and a potential alternative supplier for the same end customers.
• Anglo American (Niobium / Catalão): Diversified miner that has historically produced niobium (including the Catalão operation in Brazil) alongside a broad portfolio of base and precious metals. Overlaps with CBMM on primary niobium production but operates at much larger scale across many commodities.

Direct peers

• Niobec (Magris Resources): Canadian niobium producer operating the Niobec mine in Quebec, one of the few primary niobium producers globally. Directly comparable to CBMM in primary niobium extraction and supply to steel/alloy customers, though smaller in scale and narrower in downstream application development.

Regional players

• POSCO: Major South Korean steel producer and a meaningful consumer of ferroniobium for high-strength and stainless steel grades. Comparable as a large regional customer and competitor in advanced high-strength steel for automotive and structural applications, though primarily a customer rather than a niobium producer.
