Alclad 2014-T6, T651 Aluminum alloy,Aluminum 2014-T6, T651 alloy,E FORU

### **Alclad 2014-T6, T651 Aluminum Alloy Product Introduction** **1. Overview** Alclad 2014-T6 and T651 represent the peak-aged tempers of the 2014 aluminum alloy with protective aluminum cladding. The "Alclad" construction features a high-strength 2014 core metallurgically bonded to a corrosion-resistant pure aluminum layer. The T6 temper indicates solution heat treatment followed by artificial aging to achieve maximum strength, while T451 specifically denotes additional stress-relieving by stretching. These tempers provide the highest mechanical strength in the 2014 series combined with exceptional corrosion protection. **2.

The T6 temper achieves peak strength through artificial aging, providing the highest tensile and yield strengths available in the alloy system. The T651 variant offers additional benefits of stress-relieving, making it particularly suitable for precision machining operations where dimensional stability is critical. The Alclad construction ensures long-term durability in corrosive environments, with the pure aluminum cladding providing sacrificial protection to the high-strength core. These characteristics make Alclad 2014-T6/T651 the material of choice for critical aerospace structures, military applications, and other high-performance applications where both maximum strength and environmental resistance are essential requirements. The material's proven performance in extreme conditions establishes it as a benchmark for high-strength aluminum applications.
