What is the difference between aluminum alloys

1100

This is commercially pure aluminum (99% minimum).

It has excellent corrosion resistance, weldability, and workability, as well as high thermal conductivity.

2024

While limited in formability and workability, this alloy has high tensile strength – in the 30 to 63 KSI range.

It is used in high-strength structural and aircraft applications.

3003

This is the most commonly used commercial aluminum alloy.

It is alloyed with a small percentage of manganese and has slightly higher strength than 1100.

It is very workable and can be easily sheared and brake-formed.

This alloy offers good corrosion resistance, but does not always provide the most consistent finish in anodized applications.

5005

This alloy is very similar in properties to 1100 and 3003, and is preferred where anodizing is required.

All pre-finished anodized sheets are 5005-H34. It matches architectural alloy 6063 when anodized.

5052

This is one of the highest-strength common aluminum alloys.

Any bends tighter than 90˚ may crack or craze on the corners.

It offers very good corrosion resistance and is our second choice (after 5005) for anodizing.

Many other “common” (non-heat treatable) alloys are available with characteristics making them especially suitable for specific applications. Please inquire should you have such requirements.

6061

This is the most common structural alloy.

It offers affordability while maintaining strength and good corrosion resistance.

It is commonly used in framing and structural applications where weldability and strength are important.

Since it is harder in the T6/T651 condition than 3003 and 5005, it is not as formable; therefore, sheet may crack if brake-formed.

Honstar stocks a wide variety of extrusions in this alloy.

6063

This is an architectural alloy.

It is highly resistant to corrosion and can be anodized with very good results.

It is utilized in exterior and interior storefront, window, door, and trim applications. 

Honstar offers a wide variety of stock extrusions in this alloy in both mill finish and anodized finishes.

7075

This is one of the strongest aluminum alloys.

Formability is quite limited.

Applications are similar to 2024 alloy, with 7075 chosen when higher mechanical properties are required.
