Why Choose 2024 Aluminum Round Bar?

• Excellent fatigue resistance — ideal for cyclically loaded structures
• High strength-to-weight ratio — superior to 6061 in strength
• Good machinability — excellent surface finish after cutting
• Aircraft heritage — the original aircraft aluminum alloy
• Good damage tolerance — fracture toughness acceptable for structural use

Note: 2024 has poor corrosion resistance. Always use with alclad coating or protective anodizing for outdoor use.
