7055 aluminum is a very high-strength, heat-treatable alloy in the 7xxx series, known for offering the highest strength of any 7xxx series aluminum alloy. It is primarily alloyed with zinc, copper, and magnesium, and is specifically designed for aerospace applications where maximum strength and fatigue resistance are critical. Developed as an enhancement over 7050 and 7075, 7055 provides improved compression strength and fatigue performance, particularly in thick sections, making it ideal for demanding structural components.
