Fuji Light Metal

What Fuji Light Metal does

Fuji Light Metal Co., Ltd. (不二ライトメタル株式会社) is a Japanese manufacturer of aluminum and magnesium alloy products, headquartered in Nagomi Town (Nagasu), Kumamoto Prefecture, with a secondary manufacturing site in Ichihara (Chiba) and sales offices in Tokyo and Osaka. Founded in 1969 as Kyushu Fujisash Co., Ltd. and renamed in 2007 after the merger of Kyushu Fujisash with the Fuji Sash Materials Division, the company has been a wholly-owned subsidiary of Fuji Sash Co., Ltd. since October 2004. As of April 2025, it employs 707 people and operates with combined production capacity of approximately 7,000+ tons/month casting, 5,500+ tons/month extrusion, and 3,200+ tons/month electrolytic surface treatment, including Kyushu's first large-scale die machining center and rare 5m-length aluminum machining capability.

The company's core product portfolio is organized into four main categories: aluminum profiles (commodity shapes and custom extrusions), aluminum processed products (cutting, drilling, pressing, bending), aluminum precision machined products (micron-level components for semiconductor equipment, office equipment, and industrial machinery), and magnesium alloy products (general-purpose AZ/ZK alloys, KUMADAI heat-resistant alloys, and bioabsorbable alloys for medical stents). It also markets a small line of original consumer and commercial products (Joint Partitions, Cross Screens, Solar Mounts, Cycle Racks, aluminum mikoshi, and splash infection prevention panels). Its technology base includes the licensed Stanercote composite coating (2x weather resistance vs. standard coatings) and proprietary magnesium R&D stemming from two decades of joint research with Kumamoto University and AIST.

Fuji Light Metal operates a sales-led, B2B direct model with all revenue generated domestically in Japan. Pricing is not publicly disclosed; customers engage through direct inquiry, online business meetings, or via Tokyo/Osaka branch offices, with orders fulfilled from the Kyushu and Kanto manufacturing plants and distributed also through the Fuji Sash Group's network. End-markets span construction and building materials, automotive, home appliances, semiconductor manufacturing equipment, and medical devices. Revenue streams include aluminum extrusion sales, magnesium alloy product sales, surface treatment services, and direct-sale branded consumer products. The company is private (delisted in 2004) and does not disclose financial results, which limits external visibility into its revenue and growth metrics.
