What Are 7075 Aluminium Flat Bars?
7075 Aluminium Flat Bars are flat bars made from aluminium alloy 7075, a high-zinc, high strength alloy in the 7000 series. These flat bars are fabricated by extrusion or cold finishing to produce rectangular cross-sections with precise dimensions. As Aluminium 7075 Flat Bars, they offer high strength, good fatigue resistance, and are often used in high-stress environments. Their mechanical properties are superior to many steels on strength-to-weight ratio, making 7075 Flat Bars ideal where weight savings are as important as strength.
Â
Tempers & Their Effects
The performance of Aluminium 7075 Flat Bars depends greatly on the temper (heat treatment & work-hardening). Common tempers include:
- T6 / T651 – Solution heat treated, artificially aged, sometimes stretched. Exhibits very high tensile strength and good yield strength.
- T7351 – Treated to improve stress-corrosion cracking resistance, while maintaining high strength. Good for critical structural applications.
- Other variants (-T6511, T3511, etc.) that may provide slight differences in fatigue, machinability or form stability.Â
Advantages of Aluminium 7075 Flat Bars
- Exceptional Strength-to-Weight Ratio — These bars deliver strength comparable to mild steel while being significantly lighter.
Â
- High Fatigue Resistance — Especially in tempers engineered for improved stress-corrosion resistance, 7075 Flat Bars perform well in repetitive load conditions.
Â
- Great Machinability — In many tempers, 7075 Aluminium Flat Bars can be machined to tight tolerances and fine finishes.
Â
- Dimensional Stability — Because of stable tempers like T651 & T7351, shape retention under stress or thermal cycles is reliable.
Â
- Premium Applications Compatibility — Used in aerospace, defense, high performance automotive, precision machinery etc. where quality and performance cannot be compromised.
Â
Limitations & Considerations
- Weldability: Aluminium 7075 is generally not readily weldable in many of its strong tempers; welding may compromise the strength and stress-corrosion resistance.
Â
- Cost: As a high performance alloy, 7075 Aluminium Flat Bars are more expensive than more common alloys (6000 series etc.).
Â
- Corrosion Sensitivity: Although tempers like T7351 improve stress corrosion resistance, in certain environments (marine, high humidity, corrosive chemicals), protective coatings or finishes may be required.
Â
- Formability: Less ductile than softer alloys; bending/forming must be done with care, particularly in hardened tempers.
Â
- Weldability: Aluminium 7075 is generally not readily weldable in many of its strong tempers; welding may compromise the strength and stress-corrosion resistance.
Applications of 7075 Flat Bars
Thanks to their strength and other favourable properties, 7075 Flat Bars are used in many high-demand sectors:
- Aerospace & Defense: Structural parts, aircraft fittings, fuselage components, wing spars.
- Automotive & Motorsports: High performance or racing parts – connectors, shafts, mounts where weight reduction and strength are critical.
- Sports Equipment: Parts of bicycle frames, gears, components for climbing gear etc. where fatigue resistance matters.
- Tooling & Molds: Some tooling where high strength and dimensional stability are needed.
- Fatigue & Load Critical Industrial Machinery: Shafts, gears, load bearing components in machines exposed to cyclical stress.

Standards & Sizes
Standards / Specifications
To ensure reliability and traceability, Aluminium 7075 Flat Bars are often supplied conforming to international & industrial standards:
- ASTM B221 for bars & extruded shapes
- AMS / QQ standards – e.g. AMS-QQ-A-225/9, AMS-4122/4123/4124 for rods, bars in different shapes & tempers.
Size & Form Availability
7075 Flat Bars are available in a wide variety of widths, thicknesses, and lengths. Some common offerings include:
- Flat bars in cold finished and extruded forms.
- Thickness & width dimensions ranging from small sizes (fractions of an inch) to large industrial sizes. Custom cuts are possible.
- Standard tempers in flat bar form: T6, T651, T7351 etc.

How to Specify & Order Aluminium 7075 Flat Bars
Here are some guidelines to help you order the right 7075 Aluminium Flat Bars for your application:
- Define Temper: Decide whether T6, T651, T7351 or other temper is required based on strength, fatigue, and corrosion requirement.
Â
- Specify Dimensions: Thickness, width, length; tolerances on flatness, edge finish.
Â
- Surface Finish & Treatment: If the bar will be exposed or needs superior finish, require mill finish, cold finish, or special surface treatment/coating.
Â
- Mechanical Properties: Full yield, tensile, elongation, hardness expectations.
Â
- Standards Compliance: Ensure alloy & temper conform to recognized standards (ASTM, AMS, etc.).
Â
- Quantity & Lead Time: Flat bars may have lead times in large sizes or particular tempers.
Â
- Define Temper: Decide whether T6, T651, T7351 or other temper is required based on strength, fatigue, and corrosion requirement.
