7075 T6 T6511 Aluminum Bar Aircraft Grade

What is 7075 T6 T6511 aluminum?

7075 aluminum is a high-strength alloy from the 7xxx series, primarily alloyed with zinc, magnesium, and copper. It is commonly selected for applications requiring maximum strength and toughness.

• T6 refers to solution heat-treated and artificially aged condition.

• T6511 is a variation of T6 used for extruded products, with stress relief stretching and minor straightening applied after heat treatment. This helps reduce warping and improves dimensional stability—ideal for long aluminum bars.

Forms available: aluminum bar shapes

At Shenzhen Chinalco Metal, we supply 7075 T6 and T6511 aluminum bars in a variety of shapes to meet diverse engineering and aerospace needs. Our available bar forms include:

• Round Bar – Widely used for aircraft fittings, shafts, and structural supports due to its excellent strength and ease of machining.

• Square Bar – Ideal for connectors, brackets, and structural joints where uniform cross-section and strength in all directions are required.

• Rectangle Bar (Flat Bar) – Preferred for machined components such as mounting bases, support plates, and precision fixtures.

We maintain ready stock of common sizes and support custom cuts based on project requirements

Production methods: extruded, cold Drawn

7075 T6 and T6511 aluminum bars are primarily produced through:

1. Extrusion: The alloy is pushed through a shaped die while hot. Extruded bars in T6511 condition are stretched and stress-relieved to improve straightness and reduce internal stress.

2. Cold Drawing: After extrusion, bars may be pulled through dies at room temperature. This enhances surface finish, tightens dimensional tolerances, and increases strength—making it ideal for high-precision aerospace parts.

Both methods offer strong, consistent material ideal for CNC machining, threading, and structural integration.

Common  applications application in aircraft:

Landing gear components 

Wing spars and fuselage frames 

Seat tracks and guide rails 

Structural brackets and support bars

Engine mounts and tooling fixtures
