From raw materials to end products, we produce aluminum within an integrated model that spans the entire value chain.

At each stage of the process, our focus is on quality and minimizing impacts on the environment and surrounding communities. CBA invests constantly in improvements and state-of-the-art technology. We aim to use resources—whether natural or financial—responsibly and intelligently. As important as the aluminum we produce are our efforts to minimize waste materials from our operations, and either recycle them or ensure they are compliantly disposed of.

In a process where all sides win.

Learn more about our production process
1. Mining
Bauxite is mined in Itamarati de Minas, Miraí and Poços de Caldas, in the southeastern state of Minas Gerais, and in Barro Alto, in the Midwest state of Goiás, using best practices in sustainable land management. The bauxite ore is then beneficiated and transported—first by truck and then by rail—to the plant in Alumínio (SP). Mined land is reclaimed and returned to surface landowners with the same or better physical and chemical properties than before it was mined.
2. Beneficiation
The bauxite ore is hauled on trucks from different mine fronts for beneficiation. The ore is crushed, screened and stored in piles before being shipped to the plant in Alumínio.
3. Alumina refinery
On arrival at the Plant, the bauxite ore is blended based on its physical and chemical properties. At the Refinery, the first step in the process is extracting aluminum oxide (alumina) from the bauxite. This is achieved through chemical reactions using alkaline solutions at high temperatures, in what is known as the Bayer process. The bauxite residue, or red mud, is stored in a dam.
4. Smelters
The alumina is carried in silo trucks to smelting facilities. At the Smelters, anode paste—a mix of coal-tar pitch and petroleum coke—and electrolyte bath—consisting primarily of fluorides—are added to the alumina. Electrolytic reduction in Soderberg cells transforms the alumina into molten aluminum, which is then carried in trucks to different departments at the Casthouse.
5. Casthouse
The molten aluminum is fed along with master alloys and scrap into the Casthouse furnaces, where it is cast into ingots, billets, plate sheet, caster rolls and rod. In addition to the Alumínio (SP) plant, this process is used at our Metalex operation in Araçariguama (SP) to produce billets, and at our Itapissuma (PE) operation to produce slabs and caster rolls. Both operations use a mix of ingots and scrap.
6. Downstream
Value-added, semi-fabricated products are manufactured via rolling, extrusion and surface treatment processes. Many of these products are custom-developed with our customers to meet their stringent needs. Our Alumínio (SP) plant produces the full range of semi-fabricated products, while the Itapissuma (PE) operation is dedicated to rolled products.

CBA produces aluminum products
that are used across all three segments
of the electricity supply chain:
generation, transmission and distribution.

Generation

In generation, we provide solutions for photovoltaic panels, aluminum roofing structures for floating plants, and aluminum for large hydroelectric dam structures.

Transmission

In transmission, we supply sheet and foil to transformer manufacturers.

Distribution

In distribution, we supply aluminum profiles used to make conductor tubes for substations.

Innovation and market development

We recognize that a better future can only be built by working together. That is why we develop co-creation and co-engineering projects that leverage our delivery of solutions and create and share value from our projects.

This provides opportunities to deploy new technologies and new business models, and strengthens our long-term relationships.

methodologies

CBA has an average of 80 to 100 innovation and co-creation projects in our pipeline at any given time, using a combination of different methodologies including Design Thinking, Quick Prototyping, Lean Startup, Value Proposition Canvas, Scrum and Kanban. These projects all take environmental, social and governance considerations into account, and are led by squads—or multidisciplinary teams of experienced professionals with their own defined goals, which they work towards autonomously.

Opportunities for innovation can come from different sources, such as CBA’s IdeAl ideation program, market intelligence, technology insights, inputs from commercial teams, customer requirements, innovation programs and industry interactions. We develop those ideas into products by co-creating with our customers, who play an active role throughout the process. We also draw inputs from key players in our value chain, including suppliers, specialized consultants, research institutions, universities, end users, startups and innovation hubs.

3D printing in
advanced manufacturing
+

CBA has developed an aluminum powder designed specifically for additive manufacturing, or creating metal parts using 3D printing. Additive manufacturing is used to build parts from a digital 3D model, typically layer by layer. Products produced by this method are lighter-weight, stronger and more flexible. They are also more cost-effective and have a lower impact on the environment.

We have pioneered the development of these types of raw materials in Brazil. Our technology could make metal 3D printing a viable solution for prototyping and producing parts with complex geometries that would not be possible to build using conventional methods.

Aluminum in solar energy generation

Aluminum can make a practical difference in people’s lives. With this in mind, CBA recently joined a project, called Ilumina Pantanal, in a partnership between the Energisa Group, the state government of Mato Grosso do Sul, the Brazilian Ministry of Mining & Energy and the Brazilian power sector regulator, ANEEL. The Pantanal, a biodiversity sanctuary in the south of Brazil’s Midwest state of Mato Grosso, is home to around 2,090 families (approximately 10,000 people) living in remote communities spread across an area of 90,000 square kilometers. To supply power to these families, each property will receive an innovative system consisting of four photovoltaic modules made of recycled aluminum.

Aluminum
bus roofs
+

A world-first technology has allowed one of our customers to use aluminum instead of fiberglass to produce bus roofs, in another pioneering solution developed by CBA. It took more than 2,000 hours of laboratory testing to arrive at an optimal combination of geometry, alloy and design that would meet our customer’s requirements.

The new roof model delivered significant benefits, including:

  • Weight reduction: a 40% lighter roof improves fuel savings for conventional buses and extends the range of electric vehicles.
  • Recyclability: unlike fiberglass, aluminum from end-of-life vehicles is infinitely recyclable.
  • Strength: aluminum improves vehicle safety by reducing the likelihood of rollover accidents.
