Aluminum 2024
Description
Aluminum 2024 is one of the most widely used aerospace alloys, valued for its outstanding fatigue resistance, high strength-to-weight ratio, and excellent toughness. Its corrosion
resistance is relatively poor, so protective coatings or surface treatments are usually required. Applications include aircraft structures, automotive parts, and high-performance sports equipment.
