Aluminum 7075-T651 CNC Machining Applications & Parts

The T651 temper is the most common high-strength condition for 7075 aluminum. It provides the highest strength but is more susceptible to stress-corrosion cracking in the short-transverse direction than T7351.

Typical Parts We Machine from 7075-T651:

  • High-Stress Components: Aircraft fittings, gears, shafts, and other parts primarily stressed in the longitudinal direction
  • Molds & Tooling: Master models, foundry patterns, injection molds

Our Machining Advantage:

We understand the grain orientation and stress characteristics of 7075-T651, allowing us to machine parts that maximize its unparalleled strength for applications where ultimate performance is required.
