日本日東精工開發與鋼制螺栓同樣高強度的「Tough Alum.」鋁制螺栓
日本的汽車產業正在往減碳和自動車研發的方向加速前進，目前第一優先的課題就是車體的輕量化，日本緊固件制造商也期望做到螺栓的輕量化。有鑑于此，日東精工開發出了「Tough Alum.」高強度鋁制螺栓，它等同于鋼制螺栓的拉伸強度(420MPa以上)。
該產品使用強度高且不易發生應力腐蝕斷裂的6000系鋁材，經過熱處理后，張力強度可等同于鋼制螺栓。因此重量可以比鋼制螺栓減少三分之二，以支援顧客對產品輕量化的需求。此外，鋁表面的酸化皮膜能實現優異的耐蝕性能，與鋁制零件合併使用時能防止電蝕。將日東原創的「Flix」摩擦系數安定劑涂抹在該產品上，就能減緩鋁制品特有的磨傷的問題，只需透過低扭力就能實現軸力緊固。該產品已于11月開始販售，目標月產100萬支。
Japanese Nitto Seiko Develops "Tough Alum." Aluminum Bolt with the Same Level of Tensile Strength as Steel Bolts
The Japanese automotive industry is accelerating towards CO2 reduction and the development of seld-driving cars. Currently the top priority is lightweighting of the car body, and Japanese screw makers are also seeking lightweighting of bolts. In light of this, Nitto Seiko developed "Tough Alum." high strength aluminum bolts that has the same tensile strength (over 420MPa) as steel bolts.
"Tough Alum." uses 6000 series aluminum that is high-strength and less prone to stress corrosion crack, and after heat treatment it can attain the same level of tensile strength as steel bolts. Therefore, the weight can decrease to two thirds of a steel bolt to support customers' demand for product lightweighting. Furthermore, the oxide film on the aluminum surface can achieve excellent cossosion resistance, and prevent galvanic corrosion in conjunction with aluminum parts. Applying Nitto Seiko's original "Flix" coefficienct of friction stabilizer onto "Tough Alum." will alleviate seizing that is unique to aluminum products, achieving axial force fastening merely by low torque. "Tough Alum." has launched sales since November with a target of producing 1 million pieces per month.
