ASTM 3003 aluminum coil
In the vast world of metallurgy, aluminum alloys play a pivotal role due to their exceptional properties. One specific alloy, the ASTM 3003 Aluminum Coil, stands out for its versatility and range of applications.
ASTM 3003 aluminum alloy, also known as the "Aluminum-Manganese" alloy series, is primarily renowned for its corrosion resistance and moderate strength. Notably, these coils rank among the most commonly manufactured aluminum roll stocks due to their excellent workability, resistance to weathering, and incredible functionality.
Chemical Properties and Composition
Before diving into their technical prowess, it's paramount to assess the elemental makeup that defines ASTM 3003 aluminum. As an approximate composition standard, here’s a table detailing significant properties:
| Element | Percentage (min, max) |
|---|---|
| Aluminum (Al) | Balance |
| Copper (Cu) | 0.05 - 0.2% |
| Iron (Fe) | 0.7% max |
| Manganese (Mn) | 1.0 - 1.5% |
| Magnesium (Mg) | 0.05 max |
| Silicon (Si) | 0.6% max |
| Zinc (Zn) | 0.1% max |
| Titanium (Ti) | 0.1% max |
The predominant addition of manganese is crucial, primarily responsible for enhancing strength and improving workability without aggravating corrosion.
Tempering and Mechanical Properties
The aluminum coil can adapt widely to different tempering treatments, such as H14, H16, H18, and O tempering. Each temper influences the aluminum's mechanical properties, dictating its necessity for specific applications.
Table of Temporary Designations and Their Attributes:
| Temper Designation | Description | Approx. Yield Strength | Approx. Ultimate Tensile Strength |
|---|---|---|---|
| H14 | Strain-Hardened, unalloyed | 135 MPa | 175 MPa |
| H16 | Strain-Hardened, higher | 165 MPa | 200 MPa |
| H18 | Strain-Hardened | 200 MPa | 235 MPa |
| O | Annealed | < 55 MPa | < 110 MPa |
The temper significantly influences physical shapes and characteristics derived from applications, thereby unveiling diverse operational benefits.
