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.
