Its AMB-C product family — including AMB-C-14, AMB-C-16, AMB-C-20, AMB-C-40, and AMB-C80/AMB-C100 — is differentiated by granulometry to meet varying surface preparation standards (SA 2, SA 2 1/2, SA 3) for sandblasting, hydroblasting, corrosion removal, and coating preparation applications.

The company serves industrial surface treatment customers across Brazil, including shipyards and naval industries, metalworking and steel operations, construction and civil engineering firms, and industrial maintenance providers. Named use cases include the Maracanã Stadium restoration hydroblasting project and various naval surface treatment applications. Products are packaged in 25 kg and 1000 kg units and sold direct to enterprise customers via the company website, phone (034) 3313-3853, email, and WhatsApp, with quote-based pricing — no published price list.

Core offering

Cobau manufactures and sells 100% ecological mineral abrasive products derived from magmatic rock ore for industrial surface treatment applications. The company offers a portfolio of six product variants (AMB-C-14, AMB-C-16, AMB-C-20, AMB-C-40, AMB-C80, AMB-C100) plus the general Abrasivo Cobau line, packaged in 25 kg and 1,000 kg formats for use in sandblasting, hydroblasting, corrosion removal, and paint removal across shipyards, metalworking, construction, and industrial maintenance. Products are free of heavy metals, reusable, and designed to deliver calibrated roughness profiles (SA 2 to SA 3, grades A–D).

Product overview

Cobau offers a unified line of ecological mineral abrasives derived from igneous rock (rocha magmática), branded under the AMB-C product family. The portfolio consists of six distinct abrasive products — AMB-C-14, AMB-C-16, AMB-C-20, AMB-C-40, and AMB-C80/AMB-C100 — plus a general-purpose Abrasivo Cobau branded product. These products are designed as a cohesive system for surface treatment applications (jateamento/hidrojateamento), differentiated by granulometry, roughness level, and intended use case (from general sandblasting to high-precision hydroblasting). All products share a common formulation based on 100% natural mineral raw material, are free of heavy metals, and undergo continuous quality improvement.

Direct peers

• GMA Garnet: GMA Garnet is one of the world's largest producers of industrial garnet abrasive used for waterjet cutting and sandblasting. It is a direct comparable to Cobau as both companies supply mineral-based blasting media to industrial surface-treatment customers globally.
• Ervin Industries: Ervin Industries is a leading producer of metallic and mineral abrasive media (steel shot/grit, cut wire, and specialty abrasives). It is comparable to Cobau as a dedicated abrasive-media manufacturer serving industrial surface-treatment end users.
• Barton International: Barton International is a long-established producer of garnet and other mineral abrasives for industrial blasting. It competes with Cobau in the mineral abrasive media category, serving surface-preparation customers in metalworking, marine, and infrastructure end markets.
• Opta Minerals (part of Harsco): Opta Minerals supplies mineral abrasives, slag abrasives, and other surface-treatment media to industrial customers. It is directly comparable to Cobau as both companies provide mineral abrasive consumables for sandblasting and hydroblasting applications across multiple industries.

Emerging players

• CUMI (Carborundum Universal): CUMI is an Indian manufacturer of abrasive products including bonded, coated, and loose abrasive media. It is an emerging global player comparable to Cobau in producing industrial abrasive consumables for surface treatment and metalworking applications.
• Imerys: Imerys is a global specialty minerals group that processes mineral raw materials into industrial products including performance minerals used in abrasives and surface treatment. It is comparable to Cobau as a mineral-processor turning natural ores into value-added industrial inputs.

Broad incumbents

• Tyrolit: Tyrolit is part of the Swarovski Group and supplies bonded abrasives, grinding tools, and surface-treatment media. While primarily known for grinding wheels, it competes with Cobau in industrial surface-treatment consumables and serves overlapping customer segments.
• Saint-Gobain (Norton Abrasives): Saint-Gobain is a global materials group whose Norton brand supplies coated, bonded, and loose abrasive products. While it offers a far broader product portfolio than Cobau, it competes in the same blasting-media and surface-preparation category and represents a much larger incumbent alternative.
• 3M Abrasives Division: 3M's Abrasives Division supplies a wide range of industrial abrasive products including blasting media. Although 3M's portfolio is vastly broader than Cobau's, both companies target industrial surface-preparation customers and could converge on the ecological abrasive segment over time.

Regional players

• Wabrasivos: Wabrasivos is a Brazilian manufacturer and distributor of industrial abrasive products serving the domestic market. It is comparable to Cobau as a regional Brazilian peer competing in the same local abrasive-media segment with overlapping customers in metalworking and surface treatment.
