ALCOA 2099-T83 and 2099-T8E67 (Aluminum Extrusion Alloy)

摘要

The data in the tables show how the tempers compare in static, damage tolerant, and corrosion properties. The T83 temper can meet or exceed the strength of 7075-T6511 extrusions with improved corrosion and stiffness, and lower density. The T8E67 temper has strength much higher than 2024-T3511 or 2026-T3511 with better toughness, much better corrosion resistance, and lower density.
