Heat-Treated Alloy Aluminum Sheet 7075 T651 Temper CNC Machining
Optimized
Our 7075-T651 Heat-Treated Aluminum Sheet is a premium-grade material engineered for high-stress
applications requiring exceptional strength, precision, and
machinability. Conforming to AMS-QQ-A-250/11 and ASTM B209 standards, this aerospace-grade alloy undergoes a specialized T651
tempering process to enhance its mechanical properties, making it
ideal for CNC machining, aerospace components, and defense
equipment. Available in thicknesses from 6mm to 50mm, it delivers unmatched performance in demanding environments.
Key Selling Points:
- Ultra-High Strength: Tensile strength of 572 MPa (83,000 psi), surpassing most aluminum alloys.
- CNC Machining Excellence: Low cutting resistance and superior surface finish for
tight-tolerance parts.
- Stress-Relieved: T651 temper minimizes internal stresses, reducing warping during
machining.
- Corrosion Resistance: Chromate conversion coating (Alodine) or anodizing options for
added protection.
- Lightweight Durability: 2.81g/cm³ density, ideal for weight-sensitive applications.
