When choosing the right aluminum alloy for a project, the 3xxx series is often considered for its excellent corrosion resistance, moderate strength, and good formability. Among these, 3005 aluminum plate stands out as a versatile and cost-effective option for a wide range of industries.
Whether you’re working in construction, transportation, or food processing, 3005 aluminum plate offers a balanced combination of durability, aesthetics, and performance. In this article, we will explore the composition, mechanical properties, applications, processing characteristics, and advantages of 3005 aluminum plate. With expert sourcing and quality control, sasaaluminum supplies premium-grade 3005 aluminum plates to meet the needs of global customers.
What Is 3005 Aluminum Plate?
3005 aluminum plate is part of the 3xxx series, a group of aluminum-manganese alloys. It is an aluminum-manganese alloy with magnesium added, giving it better strength than 3003 aluminum while retaining excellent corrosion resistance and formability.
This alloy is non-heat-treatable, meaning its strength is achieved through cold working rather than heat treatment. It is widely used in sheet and plate form for applications requiring moderate strength and excellent weather resistance.
Chemical Composition of 3005 Aluminum
The chemical makeup of 3005 alloy is as follows:
| Element | Content (%) |
|---|---|
| Aluminum (Al) | Balance |
| Manganese (Mn) | 1.0 – 1.5 |
| Magnesium (Mg) | 0.2 – 0.6 |
| Iron (Fe) | 0.7 max |
| Silicon (Si) | 0.6 max |
| Copper (Cu) | 0.25 max |
| Zinc (Zn) | 0.25 max |
| Chromium (Cr) | — |
| Other elements | 0.15 max (each), 0.05 total |
Key point: The addition of magnesium gives 3005 aluminum better strength than 3003, without compromising its corrosion resistance.
Mechanical Properties of 3005 Aluminum Plate
The mechanical properties of 3005 aluminum vary depending on the temper. Common tempers include H14 (semi-hard), H18 (full hard), and H24 (partially annealed and strain-hardened).
| Property | 3005-H14 Aluminum Plate |
|---|---|
| Tensile Strength | ~190–215 MPa |
| Yield Strength | ~140–180 MPa |
| Elongation (Typical) | 10–15% |
| Brinell Hardness | ~55 |
| Density | 2.73 g/cm³ |
| Modulus of Elasticity | ~69 GPa |
These properties make 3005 suitable for moderate-load applications that require good shaping and surface finishing.
