The exact numerical difference between 5083 and 6082 is 999.
Understanding the Difference Between Aluminium Grades 5083 and 6082
While the primary question refers to a numerical difference, 5083 and 6082 are also well-known designations for specific aluminium alloys, each possessing distinct characteristics and applications. Understanding these differences provides valuable insight into their respective properties and uses.
Grade 5083 Aluminium
Aluminium alloy Grade 5083 is renowned for its high strength among all non-heat treatable alloys. Despite this, it is important to note that it is not as strong or as hard as the more commonly utilized Grade 6082.
Key characteristics of Grade 5083 include:
- High Strength: It offers the highest strength among non-heat treatable aluminium alloys.
- Form: Primarily available in plate form.
- Condition: Most commonly available in the O condition, indicating a fully annealed (soft) temper.
- Applications: Often chosen for marine applications, cryogenic applications, pressure vessels, and storage tanks due to its excellent resistance to corrosion and high strength-to-weight ratio.
Grade 6082 Aluminium
Grade 6082 is a popular medium-strength alloy known for its excellent corrosion resistance and good weldability. It stands out in comparison to 5083 for specific mechanical properties.
Key characteristics of Grade 6082 include:
- Superior Strength and Hardness: It is notably stronger and harder than Grade 5083.
- Heat Treatable: Unlike 5083, Grade 6082 is a heat-treatable alloy, which means its mechanical properties can be significantly enhanced through heat treatment processes.
- Form: Available in various forms, including extrusions, bars, and plates.
- Applications: Commonly used in highly stressed applications like offshore constructions, high-speed trains, bridges, and in general structural engineering.
Comparative Overview: 5083 vs. 6082
The table below summarizes the key differences between these two prominent aluminium grades:
| Feature | Grade 5083 | Grade 6082 |
|---|---|---|
| Numerical Value | 5083 | 6082 |
| Difference | -999 (relative to 6082) | +999 (relative to 5083) |
| Alloy Type | Non-heat treatable | Heat treatable |
| Strength | Highest among non-heat treatable alloys | Higher than 5083 |
| Hardness | Less hard than 6082 | Harder than 5083 |
| Primary Form | Plate | Various (e.g., extrusions, bars, plates) |
| Common Temper | O condition (fully annealed) | T6 (heat-treated and artificially aged) |
| Corrosion Res. | Excellent (especially in marine environments) | Excellent |
| Weldability | Good | Good |
In essence, while the mathematical difference is a simple calculation, the material difference highlights that Grade 6082 generally offers superior strength and hardness due to its heat-treatable nature, making it suitable for more demanding structural applications where higher mechanical properties are critical. Grade 5083, conversely, excels in applications requiring high strength in a non-heat-treated condition, particularly where formability and corrosion resistance are paramount.
