Aluminum sheets are a versatile material that is used in a wide variety of applications. Two of the most common aluminum alloys are 5052 and 6061. These alloys have different properties, so it is important to choose the right one for your specific application.
What are Aluminum Sheets?
Aluminum sheets are thin, flat piece of aluminum that is used in a variety of applications. They are typically made by rolling aluminum ingots into a sheet. Aluminum sheets are available in a variety of thicknesses, widths, and lengths.
What are the 5052 and 6061 Aluminum Sheets?
The 5052 and 6061 aluminum sheets are both non-heat-treatable alloys. This means that their properties cannot be changed by heat treatment. However, they can be strengthened by cold working.
The 5052 aluminum sheet is a general-purpose alloy that is known for its corrosion resistance. It is also relatively ductile, meaning that it can be bent and stretched without breaking.
The 6061 aluminum sheet is a high-strength alloy that is known for its machinability. It is also relatively corrosion resistant.
Properties of 5052 and 6061 Aluminum Sheets
Mechanical Properties
The mechanical properties of 5052 and 6061 aluminum sheets are shown in the table below.
| Property | 5052 | 6061 |
| Tensile strength (MPa) | 220 | 276 |
| Yield strength (MPa) | 193 | 241 |
| Elongation (%) | 25 | 12 |
As you can see, 6061 aluminum sheet is stronger than 5052 aluminum sheet. However, 5052 aluminum sheet is more ductile than 6061 aluminum sheet. This means that 5052 aluminum sheet can be bent and stretched more without breaking.
Physical Properties
The physical properties of 5052 and 6061 aluminum sheets are shown in the table below.
| Property | 5052 | 6061 |
| Density (g/cm³) | 2.7 | 2.7 |
| Specific heat (J/kg·K) | 920 | 920 |
| Thermal conductivity (W/m·K) | 138 | 167 |
As you can see, 6061 aluminum sheet has a higher thermal conductivity than 5052 aluminum sheet. This means that 6061 aluminum sheet can dissipate heat more efficiently.
Chemical Properties
The chemical properties of 5052 and 6061 aluminum sheets are shown in the table below.
| Property | 5052 | 6061 |
| Corrosion resistance | Good | Good |
| Weldability | Good | Good |
| Machinability | Good | Excellent |
As you can see, both 5052 and 6061 aluminum sheets are corrosion resistant. However, 5052 aluminum sheet is slightly more corrosion resistant than 6061 aluminum sheet.
