Aluminum Material Selection Guide: Forged Aluminum vs. Rolled Aluminum
In critical sectors bearing extreme stress, facing harsh corrosion, or demanding stringent welding performance (aerospace, shipbuilding, heavy equipment, high-end chemical processing), the decision on selecting an aluminum plate often determines the success or failure of a project. Faced with a wide array of aluminum alloy grades and the two core processes of forging and rolling, precise matching of requirements is essential to unlock the material’s maximum value. Process Showdown: Power Shaping vs. Ductility Control Forged Aluminum Plate Under thousands of tons of pressure, a heated aluminum ingot undergoes a high-pressure “reshaping rebirth.” The metal’s grain flow is tightly reconstructed around the mold, completely closing internal pores and achieving ultra-fine grains and high densification. This results in unparalleled fatigue resistance, exceptional multi-directional uniform strength, and superior fracture toughness. It is the ultimate choice for enduring complex alternating loads and high impacts (e.g., aircraft keel beams, armored vehicle base plates, ultra-high-pressure valve bodies). Hot Rolled Aluminum Plate A heated aluminum ingot is repeatedly stretched and thinned between massive rollers. This process is efficient and economical, capable of producing extremely large-sized (thickness >200mm, width >3000mm) plates with stable performance. Rolling preserves aluminum’s natural excellent ductility, outstanding weldability, and good corrosion resistance. It...
