Concentration2024
Titanium begins as "sponge" — the porous primary metal made by the energy-intensive Kroll process of reducing titanium tetrachloride — and only a handful of plants in the world make aerospace-grade sponge: Russia's VSMPO-Avisma, Japan's Toho Titanium and Osaka Titanium, plus Chinese and US producers. Toho is one of the key non-Russian sources. So beneath the titanium mills (like TIMET) that roll the sheet and forge the parts sits an even narrower tier — the sponge makers — and Japan's two sponge producers are strategically vital to keeping Western aerospace supplied with non-Russian titanium. The deepest titanium chokepoint isn't the finished forging; it's the sponge, concentrated in very few countries and very few energy-hungry plants, which makes a Japanese sponge maker a quiet linchpin of the global aerospace and defense supply chain.

Toho Titanium is also moving into the EV battery supply chain. Alongside titanium sponge, it makes nickel-based cathode materials and precursors for lithium-ion batteries, applying its metal-refining and high-purity inorganic chemistry to energy-storage materials. So a titanium-sponge maker — supplying the metal for jet engines, eyeglass frames and medical implants — is simultaneously building cathode materials for electric vehicles. The competency transfers: the chloride metallurgy and controlled high-purity reduction behind titanium sponge are close cousins of the precision inorganic synthesis behind battery cathodes. It is an unexpected bridge from aerospace metal to energy storage, with one Japanese company straddling both the legacy strategic-metals world and the battery-materials future.
