2026-02-05
Born from a joint patent between Yamashina and Nippon Light Metal Company in Japan, the game-changing automotive aluminum bolt "ALTIMA" is now available. Surpassing traditional designs, it prioritizes durability and safety by mitigating stress corrosion cracking risks from prolonged stress concentration. Matching the corrosion resistance of legacy bolts used in European and select Japanese cars, ALTIMA boosts strength by over 10%. It is built on the July 11, 2024 joint patent (No. 7496106) and four years of rigorous safety validation.
Features: Tensile strength over 460 MPa, yield strength over 380 MPa—equivalent to JIS aluminum grade AL5 (one tier above conventional AL4)—with anti-cracking and void-free processing for flawless internals. Targeting EVs, unmanned aerial mobility, robots, inverters, batteries, aluminum busbars, and eco-infrastructure, it excels in lightweighting, non-magnetism, conductivity, corrosion resistance, and anti-loosening, supporting low-carbon circular economies. Nippon Light Metal and other partners will continue collaborating to expand.
ALTIMA doesn't just enhance vehicle safety—it powers the green mobility revolution and sets new precision manufacturing benchmarks.
