Aluminum comes in a range of different alloys, each with different chemical compositions and characteristics suitable for various applications. Aluminum alloy 6005 is ideal for applications that require high corrosion and moderate strength. At Tri-State, we offer aluminum alloy 6005 and other aluminum alloys to suit your unique applications. Aluminum alloy 6005 possesses many desirable properties applicable to a variety of applications and industries.

Aluminum Alloy 6005 vs. Aluminum Alloy 6005A

Aluminum alloys in the 6000 series have magnesium and silicon as their main elements and are strengthened through heat treatment. This combination improves corrosion resistance, formability, strength, and weldability, making them suitable for many different applications.

When comparing Aluminum Alloy 6005 and 6005A, they differ in chemical composition but are similar in some applications. For instance, Aluminum 6005 has a high silicon amount, reducing its melting point but improving its extrudability.

Aluminum alloy 6005A also has more chromium to reduce the risk of stress corrosion and increase its toughness. It also has extra manganese to improve its extrudability and strength.

Though both alloys have excellent bending properties, they aren’t ideal for applications that experience frequent overloading or impact. You should also note that these two alloys perform poorly in producing thin-walled, complicated shapes.

Finally, these two alloys are easy to braze and weld in commercial applications. However, the heat from the welding reduces its strength. Additional characteristics include good corrosion resistance, enhanced finishing properties, and compatibility with anodizing methods such as dying, hard coating, and coloring.

Aluminum Alloy 6005 vs. Aluminum Alloy 6061

Aluminum alloy 6005 has similar characteristics to 6061 when produced through a -T5 temper. They have identical yield and tensile strength and offer better machinability than the Aluminum alloy 6063-T6. Despite these similarities, Alloy 6005A outperforms 6061 due to its improved extrudability and surface appearance.
