7075-T73 Aluminum is the industry benchmark for applications requiring a unique combination of ultra-high strength and superior resistance to environmental degradation. The T73 temper distinguishes this alloy through a specialized double-aging process that significantly enhances its resistance to stress corrosion cracking—a critical factor for components exposed to tensile stress and corrosive atmospheres, such as marine environments or chemically active industrial settings. While delivering the high strength characteristic of the 7075 family, this specific temper offers a level of stability and safety that standard T6 tempers cannot match.
