Daiki Aluminium Industry

What Daiki Aluminium Industry does

Daiki Aluminium Industry Co., Ltd. (株式会社大紀アルミニウム工業所) is a Japanese publicly listed secondary aluminum alloy manufacturer and one of the pioneers of the country's aluminum recycling industry. The company processes used aluminum scrap — used beverage cans (UBC), window frame sashes, and industrial scrap — through melting, refining, and casting into JIS-standard alloys (ADC12, AD1.1, AD3.1, etc.) and a portfolio of proprietary specialty alloys including the NA high-strength/high-ductility series (NA-3, NA-5, NA-6, NA-8, NA-11, DIKNA-9), HT high-thermal-conductivity series (HT-1, HT-2, DIKHT-3), CR-1 high-corrosion-resistance alloy, ECA2 low-temperature casting alloy, DIK365 European-style structural alloy, and Hi-Si high-wear alloys. The company is organized around the DIK Network, integrating scrap collection (Daiki Material), non-ferrous metal trading (Tokyo Aluminium Center), furnace engineering (Daiki Engineering), and die casting (Seishin Seisakusho), and operates across 8 countries and 28 locations with manufacturing subsidiaries in Japan, India, Indonesia, Malaysia, Thailand, and the Philippines, plus a US trading arm.

The business model combines B2B direct sales of alloy products (JIS-standard and proprietary), molten aluminum delivery (crucible-direct to customer shops, eliminating customer re-melting and yielding 1,620 tons/year CO2 reduction per 1,000 tons/month contract), sale of aluminum ash (30-50% Al content) to steelmakers as deoxidizer and slag modifier, dross processing technology licensing for external parties, and ISO/IEC 17025 accredited Technical Center services for joint development and quality evaluation. GTM is enterprise field sales with technical-support engineers embedded at customer sites, targeting aluminum alloy manufacturers, die casting companies, automotive parts makers, precision equipment manufacturers, and non-ferrous metal traders. Primary customer verticals are automotive and motorcycle OEMs/tier suppliers (engine blocks, transmissions, chassis, structural parts, heat sinks, LED headlights), with secondary exposure to precision equipment, construction/sash, beverage-can rolling mills, and steel manufacturing. The company holds patents on its proprietary alloy families and proprietary measurement devices (DIK molten aluminum cleanliness evaluation device, reduced-pressure solidification tester), and operates under ISO9001 (since 2003) and OSHMS (2009-2012) certifications across all major sites.
