Comparison between 5052 aluminum plate H32 and H34

Comparison between 5052 aluminum plate H32 and H34

5052 aluminum plate is a widely used 5000 series aluminum alloy plate (aluminum-magnesium alloy). 5052 aluminum plate has excellent corrosion resistance, machinability and high strength-to-weight ratio.

Although 5052 aluminum alloy has strong performance, the performance of 5052 aluminum plate in different tempering states is also quite different. Today we compare the most common H32 and H34 states to understand the performance differences brought by different tempering states.

What 5052 H32 and 5052 H34 aluminum plates have in common

5052 H32 and 5052 H34 are two temper designations for 5052 aluminum sheet plate. Although they have some differences in mechanical properties, they share some similarities, making them both popular choices in a variety of applications. Here’s what 5052 H32 and 5052 H34 aluminum sheets have in common:

Chemical composition:

H32 and H34 steels are primarily composed of 5052 aluminum alloy. This composition provides a solid foundation for its mechanical and corrosion-resistant properties.

Corrosion resistance:

One notable similarity is their excellent corrosion resistance. Both H32 and H34 are highly corrosion-resistant and suitable for use in environments with moisture and other corrosive elements.

Solderability:

The weldability of both steel grades is very good. Weldability enables it to be adapted to a variety of manufacturing processes, providing flexibility for manufacturing and construction applications.

Recyclability:

Both 5052 H32 and 5052 H34 aluminum sheets are recyclable and environmentally friendly. Recycling these alloys does not compromise their essential properties and contributes to sustainable practices.

Performance Differences between 5052 H32 and 5052 H34 Aluminum Sheets

The main differences between 5052 H32 and 5052 H34 aluminum sheets are their mechanical properties, tempering processes, and specific applications. Here are the main differences:

1. Mechanical Properties:

Tensile Strength: 5052 H34 generally has higher tensile strength than 5052 H32. H34 undergoes a more extensive cold working process, which increases its strength.

Yield Strength: Similar to tensile strength, 5052 H34 generally exhibits higher yield strength than 5052 H32.

Elongation: 5052 H32 tends to have higher elongation, indicating better formability. H34 may have slightly lower elongation due to increased strength.

2. Hardness and Tempering:

The names “H32” and “H34” refer to the tempering process used for the aluminum sheet.

H32 (Quarter Hard): This temper is strain hardened and stabilized, giving it good formability while maintaining some strength.

H34 (Stabilized): This temper involves a higher degree of strain hardening, resulting in higher strength and hardness compared to H32.

3. Formability:

5052 H32: Known for its excellent formability, making it suitable for applications where forming and bending are critical, such as building and construction uses.

5052 H34: While still formable, it may not be as ductile as H32 due to the higher degree of strain hardening. It is generally used in applications where increased strength and resistance are required.

4. Machinability:

Both steels generally have better machinability. However, due to the higher hardness of H34 steel, it may present some challenges in certain machining processes compared to H32 steel.

From the above description, it can be seen that the main difference between 5052 aluminum plate H32 and H34 is in mechanical properties. Although they are different, they are all 5000 series aluminum-magnesium alloys after all, and the difference is minimal. They can replace each other in many application scenarios. However, if there are special requirements for strength and processing performance, we must consider the difference in mechanical properties between H32 and H34.
