Gränges AB, founded 1896 and based in Stockholm, produces rolled and recycled aluminium—including battery cathode foil, cell casings and cooling plates—for automotive, EVs, energy storage and packaging, focusing on recyclable materials and low carbon footprints.
Gränges AB, founded in 1896 in Grängesberg and headquartered in Stockholm, Sweden, is a global producer of rolled and recycled aluminium. The company supplies high‑performance foils and sheets for thermal management, packaging and electrification, including battery cathode foil, cell casings and cooling plates. Gränges aims to provide circular, low‑carbon aluminium solutions and supports a transition toward climate neutrality by 2040 through alloy development, regional production and verified product carbon footprints. The company employs about 3,500 people and operates production sites across Europe, Asia and the Americas.
Gränges’ core technology combines alloy development, aluminium rolling and recycling to produce thin, high‑precision foils and sheets. Manufacturing steps include direct‑chill casting, remelting, hot and cold rolling plus finishing (tension leveling, slitters, cut‑to‑length and chemical treatments) to meet tight thickness and surface tolerances. Differentiators include low‑gauge cathode foil production, specialized alloys for battery casings and cooling plates, third‑party verified product carbon footprints and site-level renewable power. The Gränges Production System supports lean operations and higher recycled content, improving lifecycle environmental performance and material safety in EV and thermal‑management applications.
Gränges supplies flat‑rolled coils, sheets and thin cathode foils for heat exchangers, EV battery components, buildings and recyclable packaging. Key items include battery cathode foil, battery cell casings and cooling‑plate sheets (notably the Gränges Endure range). Products offer lightweight construction, high thermal conductivity, recyclability, and verified low carbon footprints for automotive, energy storage, consumer electronics and industrial uses.
In the past year Gränges advanced battery‑material capacity and sustainability projects: a SEK 600 million expansion at Finspång that doubled battery cathode foil capacity and reinforced the site as a center of excellence; commissioning renewable‑powered production at Newport, Arkansas to supply domestic BCF; and a strategic plant acquisition in Shandong to expand Asian capacity, collectively lifting battery‑material output and supporting higher sales volumes in 2025.
Gränges is publicly listed with roughly 106.5 million shares outstanding. Institutional investors hold about 63.7% and the general public about 30.8%. Major shareholders include the Fourth Swedish National Pension Fund (AP4), Afa Försäkring, KGH Ltd., Swedbank Robur and Unionen Investment Management. The shareholder base emphasizes long‑term institutional ownership and the company funds growth through operating cash flow and targeted regional investments.
