What Almatis does
Almatis is a privately held global manufacturer of specialty alumina products headquartered in Frankfurt, Germany (registered office Almatis B.V. in Botlek RT, Netherlands) and owned since 2015 by OYAK, the Turkish pension fund. The company operates nine manufacturing facilities across three continents (Netherlands, Germany, Japan, China, India, and the United States), supported by 14 global sales, research, and manufacturing centers, a Singapore distribution hub, and six application and development laboratories. Its operations trace back to 1910 and the invention of tabular alumina in 1934, and the company has been an independent entity since the 2004 Alcoa spin-off.
The company's core technology centers on calcined alumina, tabular alumina, reactive alumina, calcium aluminate cement, spinels, and dispersing aluminas, marketed under proprietary brands such as ECO-TAB, ThermaFill, Alphabond, Caro White, GILOX, RAPOL, ULTIMATE, and AR 78/90 spinels. These products serve six end-markets on a horizontal basis: refractories (the primary segment, including steel ladle linings and cement kilns), ceramics, polishing, specialty industries (aerospace, defense, electronics, investment casting), building chemistry, and glass. Notable process and product innovations include the ECO-TAB sustainable tabular alumina, the Iwakuni pneumatic conveying upgrade (April 2025), and local production of AR 78/AR 90 spinels at Huangdao.
Almatis generates revenue through direct B2B sales of specialty alumina materials under quote-based pricing, supplemented by regional distribution partners covering Europe, Africa, and other markets. The go-to-market is sales-led, supported by industry trade shows, technical webinars, WeChat and LinkedIn presence, and a global distribution network now unified in Europe (Stockmeier/Bassermann) and sub-Saharan Africa (Mineral Zone/Cofermin). A strategic collaboration with Çimsa (June 2025) cross-sells complementary CAC products and explores joint capacity expansion, while a June 2026 refinancing expanded committed financing to approximately EUR 350 million with maturity to 2033 to fund growth.
