Primary Types
Aluminium 5052 sheets are available in several primary types, distinguished by their tempering processes. These temper designations significantly impact the mechanical properties and formability of the sheets. The primary types include:
1. H32:
Aluminium 5052 sheets in the H32 temper are strain-hardened and stabilized, featuring a quarter-hard temper. This temper provides moderate strength and excellent formability, making it suitable for a wide range of applications, including automotive panels, marine components, and architectural structures.
2. H34:
Sheets in the H34 temper undergo further strain-hardening compared to H32, resulting in a half-hard temper. This temper offers increased strength and improved resistance to deformation, making it ideal for applications requiring enhanced structural integrity and durability, such as aircraft fuselage panels and pressure vessels.
3. H36:
Aluminium 5052 sheets in the H36 temper are subjected to additional strain-hardening, achieving a three-quarters hard temper. This temper provides greater strength and stiffness while maintaining good formability, making it suitable for applications requiring high tensile strength, such as truck trailer bodies and chemical processing equipment.
4. H38:
Sheets in the H38 temper undergo maximum strain-hardening, resulting in a full-hard temper. This temper offers the highest level of strength and hardness among the primary types, making it suitable for demanding applications where superior mechanical properties are essential, such as aerospace components and structural parts subjected to heavy loads.
Key Dimensions
Aluminium 5052 sheets are manufactured in various thicknesses, widths, and lengths to suit different applications. Common dimensions include:
Thickness: Typically ranges from 0.2 mm to 6.35 mm (0.008 in to 0.250 in).
Width: Commonly available in widths ranging from 600 mm to 2000 mm (24 in to 79 in).
Length: Standard lengths vary but are often supplied in coil or sheet form, with customizable lengths available upon request.
Equivalent Grades
Aluminium 5052 is comparable to several other aluminium alloys, to name a few:
AA 5052: The Aluminium Association (AA) designation for Aluminium 5052
EN AW-5052: European designation for Aluminium 5052
A95052: Unified Numbering System (UNS) designation for Aluminium 5052
Sheet Weight & Sizes
The weight of Aluminium 5052 sheets depends on their dimensions and thickness. As a general guideline, the weight can be calculated using the formula: Weight = Length × Width × Thickness × Density. Aluminium 5052 sheets are available in various standard sizes, typically ranging from small sheets suitable for DIY projects to large industrial-sized sheets. Common sheet sizes include:
Standard: 4 ft × 8 ft (1.22 m × 2.44 m)
Large: 5 ft × 10 ft (1.52 m × 3.05 m)
