 Innovate Alumina and beyond for tomorrow – Almatis is the world leader in specialty alumina solutions. Prioritizing safety, quality, sustainability, innovation, and reliable supply. We service our customers with the most innovative specialty alumina products.

From steelmaking industry and technical ceramics, to medical applications and thermal management industries, Almatis aluminas boost your efficiency, improve your specific consumption, and reduce your energy use and carbon footprint.

Almatis’ innovative products such as ECO-TAB® contribute to your resource savings, capacity improvement, and reduced material consumption while maintaining long refractory life.

Almatis´ higher purity extra-low and ultra-low calcined alumina products support our customers in the technical ceramic, semiconductor and similar associated industries in achieving products with improved dielectric performance and improved chemical resistivity under harsh conditions.

Besides higher purity, Almatis is focusing on offering even finer products needed for improved performance of ceramics. Reactive aluminas can be offered in submicron sizes having tight top cuts for best performance.

For customers in the polishing industry, Almatis is offering the broadest portfolio of alumina based products. Newest developments like the Ultimate series of products, focus on combination of high cut and exceptional shine.

Our market leading portfolio of products include recently launched calcined aluminas featuring extra-low and ultra-low soda levels, ThermaFill products for the thermal management market, eco-friendly & lower carbon aggregate solutions for the refractory industry and high whiteness calcium aluminate cements and many other specialty products. They are known to perform consistently, anywhere, anytime, every time.

The Almatis legacy and leading position in the industry is distinguished by more than 100 years of research and development into alumina.

With 1000 employees in 8 production locations around the world, Almatis has the largest operational footprint in the industry. We are focused on regional supply chain solutions and in increasing our production capabilities for regional markets and customers.

Think alumina, think Almatis.

Market leadership

Innovate Alumina and beyond for tomorrow. Almatis leads by focusing on quality products, customer-focused service & support, and reliable supply. As devices continually become smaller and soon may be printed at home, energy comes in the re-chargeable kind, and full-time - real-time connectivity is less a trend than a reality, Almatis aluminas enable the development of next-generation technologies. Across our core & emerging markets, Almatis offers the most comprehensive portfolio in the industry, with products that are known to perform consistently, anywhere, anytime, every time.

Special know-how

With more than 100 years of expertise in development, manufacture and supply of premium specialty aluminas and alumina-based products Almatis offers the most comprehensive alumina product port-folio in the industry, including: tabular aluminas, calcined and reactive aluminas, polishing aluminas, calcium aluminate cements, brown sintered alumina, spinels, thermal insulating aggregates and others. Across our core markets – refractories, technical ceramics and polishing – our products are used in a wide variety of industries including ceramic, automotive, polishing and electronics, iron and steel, cement, nonferrous metal.

ThermaFill: Alumina Functional Fillers for Thermal Applications

ThermaFill products are specially designed alumina fillers to yield higher performance in thermal interface applications. Alumina fillers provide a cost-effective option to increase thermal conductivity in polymer systems such as silicone, epoxy and more. The lower viscosity and greater packing efficiency achieved with ThermaFill allows higher filler loading and increased thermal conductivity.
