Aluminum 7475

Aluminum Alloy 7475, derived from Aluminum 7075, provides excellent toughness for a broad variety of applications. This alloy offers several metalworking options that include machining, forming, and heat treating.

For machining, Aluminum Alloy 7475 functions best in the annealed condition and should be used with oil-based lubricants. It is also most easily formed in the annealed condition, as its hardened state results in spring-back.

Alloy 7475 also works well for conventional cold working. Operations such as spinning are possible if the alloy is warmed to 250°F.

The chemical composition of Aluminum Alloy 7475 falls within the following parameters:

• Cu 1.2-1.9%
• Mn .06%
• Mg 1.9-2.6%
• Fe .12%
• Si .10%
• Zn 5.2-6.2%
• Cr .18-.25%
• Ti .06%

This alloy is typically available in flat rolled products, and it is widely used for applications that require high strength, including planes and other aerospace assemblies.

All alloys distributed by Anita Steel & Metals meet or exceed the industry’s most exacting standards, including UNS A97475. To learn more about Aluminum Alloy 7475 or any of the other metals we distribute, please contact one of our experts today.

Aluminum 7178

Aluminum Alloy 7178, comprised of copper and magnesium as its primary alloying elements, offers uncompromising strength and accommodates a number of different metalworking processes. These processes include machining, welding, and heat treating.

When annealed, Aluminum Alloy 7178 offers good machinability and also responds well to resistance welding. Heat treatment should be performed at 875 °F with a subsequent water quenching. After treatment, this alloy gains precipitation hardening which improves its mechanical properties. Heavier thicknesses are formable.

The chemical composition of Aluminum Alloy 7178 falls within the following parameters:

• Cu 1.6-2.4%
• Mn .30%
• Mg 2.4-3.1%
• Fe .50%
• Si .40%
• Zn 6.3-7.3%
• Cr .18-.35%
• Ti .20%

This alloy is preferred for many applications in the marine, construction and aerospace industries.  Aluminum Alloy 7178 from Anita Steel & Metals Company meets or exceeds all relevant industry standards. These standards include all appropriate ASTM, QQ, SAE, and UNS specifications.

We offer Aluminum Alloy 7178 in coil form or as shapes.   To learn more about this alloy or to determine which aluminum alloy will work best in your next project, please contact us directly.

Aluminum 7075

Aluminum 7075 is a high-strength alloy that offers good stress-corrosion cracking resistance. Known as a mainstay in the aerospace industry since it was introduced, Aluminum 7075 brings moderate toughness as well as an excellent strength-to-weight ratio. It is also important to note that at sub-zero temperatures Aluminum 7075 increases in strength.

When it comes to welding, the resistance welding is preferred, while gas and arc welding should be avoided. It is available in in the clad (Alclad) form to improve corrosion resistance.

Due to these outstanding benefits, Aluminum 7075 is used extensively for a number of applications including:

• Highly stressed structural parts
• Aircraft fittings
• Gears and shafts
• Fuse parts
• Meter shafts and gears
• Missile components
• Regulating valve parts
• Worm gears
• Other aerospace and aircraft parts

The unique chemical composition of Aluminum 7075 includes:

• Al balance
• Zn 5.1-6.1%
• Mg 2.1-2.9%
• Cu 1.2-2.0%
• Mn 0.30%
• Fe 0.50%
• Si 0.40%
• Ti 0.20%
• Cr 0.18-0.28%

All of the Aluminum 7075 available from Continental Steel meets or exceeds a variety of specification including those from AMS, ASTM, QQ, MIL, and SAE.

Aluminum 7050

Aluminum 7050 is a heat treatable alloy that has very high mechanical properties and high fracture toughness. Popular with the aerospace industry, Aluminum 7050 offers good stress and corrosion cracking resistance and high strength at subzero temperatures.

It is available in two tempers T7451 and T7651 and it has the electrical conductivity 40% of copper. Welding should be avoided with Aluminum 7050, as the process weakens the alloy. Most of the Aluminum 7050 in plate form comes in thicknesses over 2”.

Applications for Aluminum 7050 mostly revolve around the aerospace industry, these include:

• Fuselage frames
• Bulkheads
• Various aircraft parts

To be called Aluminum 7050, an alloy must contain a certain chemical composition that includes:

• Al 89%
• Cu 2.3%
• Mg 2.3%
• Zn 6.2%
• Zr 0.12%

Anita Steel & Metals offers Aluminum 7050 in a variety of shapes and sizes including sheet, plate, and bar.
