##Properties of 6061-T4 Aluminum Sheet

A Perfect Blend of Strength and Flexibility

One of the main reasons 6061-T4 aluminum sheet is widely used across various industries is its excellent balance of strength and flexibility. This particular aluminum alloy boasts a yield strength of around 35,000 psi and an ultimate tensile strength of 38,000 psi. However, what makes it truly unique is the fact that it has great formability and elasticity, ensuring that it won’t crack or break under stress.

Impressive Corrosion Resistance

Another noteworthy characteristic of the 6061-T4 aluminum sheet is its fantastic resistance to corrosion. Thanks to the addition of chromium and magnesium in its composition, it offers superb protection against pitting, stress corrosion cracking, and general, uniform corroding in various environments.

Optimal Weldability

When it comes to welding, the 6061-T4 aluminum sheet is a top choice for many professionals. The alloy can be easily welded using common fusion and resistance welding techniques and typically has no issues retaining its mechanical properties after the process.

Superior Machinability

The 6061-T4 aluminum sheet also boasts excellent machinability, making it a go-to choice for manufacturers who require precise dimensions and intricate designs. It can be easily cut, shaped, drilled, and bent to suit a wide range of requirements.

Frequently Asked Questions About 6061-T4 Aluminum Sheet

What does ‘T4’ stand for?

The ‘T4’ designation indicates that the 6061 aluminum sheet has been subjected to a specific heat treatment known as “solution heat treatment and natural aging.” This process significantly enhances the material’s mechanical properties and corrosion resistance.

How does 6061-T4 aluminum sheet compare to 6061-T6?

While both 6061-T4 and 6061-T6 are part of the same aluminum alloy family, the main difference is their temper or heat treatment process. The 6061-T4 aluminum sheet is not heat-treated to the same extent as the 6061-T6, resulting in it being slightly less strong and more flexible. However, it’s still suited to a wide range of applications and offers excellent corrosion resistance.

Can 6061-T4 aluminum sheet be anodized?

Yes, the 6061-T4 aluminum sheet is a suitable material for anodizing. The process of anodizing creates a protective oxide layer on the material’s surface, further increasing its corrosion resistance and giving it an attractive finish.


With incredible properties like excellent strength, flexibility, corrosion resistance, and more, it’s no wonder that the 6061-T4 aluminum sheet is a popular choice for a wide range of applications. By opting for this versatile and cost-effective material, you’ll not only benefit from its fantastic characteristics and lightweight nature but also contribute to a more sustainable world through its high recyclability.

Whether you’re tackling a construction project, building components for the automotive or aerospace industries, or even designing sporting equipment, the 6061-T4 aluminum sheet is a material that simply can’t be overlooked. So, what are you waiting for? Discover the incredible world of 6061-T4 aluminum sheet today and explore all the unique benefits and applications that it has to offer.
