Exploring the Different Tempers of 3105 Aluminum Sheet & Plate

3105 - O

The 3105-O aluminum sheet is the fully annealed version of the 3105 aluminum alloy.
After annealing, this alloy exhibits exceptional ductility and steady mechanical properties, making it a preferred material for crafting intricate structures and precision parts. Its diverse applications, particularly in parts requiring high ductility and flexibility, make it an invaluable asset.

3105 - H14

The 3105-H14 aluminum plate is a semi-hard variant of the 3105 aluminum alloy that has been treated to increase its strength.
This alloy has excellent forming properties, high strength, and retains exceptional welding properties and corrosion resistance. It is commonly used in many industrial fields and for structural components.

3105 - H24

This is the 3105-H24 aluminum sheet. It’s a semi-hard type of the 3105 aluminum alloy that has undergone extensive hardening treatment.
It’s strong, fatigue-resistant, and easy to weld. Plus, it can resist corrosion well. This makes it ideal for parts in high-stress areas like cars, buildings, and pressure vessels.
