Introduction<\/strong><\/b><\/p>\n

    \n
  1. Aluminum Steel Clad Plate is a bimetal composite that permanently bonds aluminum to carbon steel or stainless steel through explosive bonding or roll\u2011bonding technology. The steel side provides high strength, stiffness, and good weldability to conventional steel structures, while the aluminum side offers low density, good corrosion resistance, and excellent machinability. This material is widely used as a structural transition joint and lightweight solution in shipbuilding, marine engineering, rail and automotive structures, bridge decks, cryogenic tanks, and other applications where aluminum components must be reliably connected to steel.<\/li>\n

    \n

    We offer fully customizable Aluminum Steel Clad Plates, including aluminum alloy grade (e.g., 1050, 1060, 3003, 5083) and base steel grade (e.g., Q235\/Q345, A36, A516, or stainless steel), as well as total thickness, cladding thickness, plate width\/length, and edge machining according to your drawings. The plates feature strong metallurgical bonding, high shear strength, good formability, and compatibility with welding procedures on the steel side and mechanical\/bolted or special welding solutions on the aluminum side. They are manufactured with reference to relevant ASTM\/EN\/GB standards and can be supplied with ultrasonic testing and material certificates for critical projects. OEM\/ODM and engineering support are available for shipyards, fabricators, and infrastructure projects.<\/p>\n
