1050 aluminum plate: The Pure and Versatile Backbone of General Industry
Looking for a high-purity aluminum plate with excellent conductivity and formability?
1050 aluminum plate and sheet, supplied by GNEE, represent one of the most reliable and cost-effective solutions for applications where corrosion resistance, conductivity, and workability matter more than extreme strength.
Within the aluminum alloy family, the 1000 series is synonymous with purity-and Aluminium 1050 stands out as a benchmark grade, offering a minimum 99.50% aluminum content and consistent, predictable performance across industries.
1050 aluminum plate Composition: The Essence of Purity
The outstanding properties of 1050 aluminum sheet and plate are directly tied to its high purity and strictly controlled impurity levels.
Chemical Composition of Aluminium 1050 Plate
| Element | Content (%) |
|---|---|
| Aluminum (Al) | ≥ 99.50 |
| Iron (Fe) | ≤ 0.40 |
| Silicon (Si) | ≤ 0.25 |
| Copper (Cu) | ≤ 0.05 |
| Manganese (Mn) | Trace |
| Magnesium (Mg) | Trace |
| Zinc (Zn) | Trace |
| Other elements | Strictly limited |
Compared with 1100 aluminum, the lower Fe and Si content in 1050 aluminum plate results in higher electrical and thermal conductivity, as well as improved ductility. It sits between 1100 and ultra-pure grades such as 1145 or 1350, making it a true general-purpose pure aluminum alloy.
Core Properties of 1050 aluminum plate
Superior Corrosion Resistance
Like all high-purity aluminum alloys, 1050 aluminum plate naturally forms a dense, self-healing aluminum oxide (Al₂O₃) layer. This protective film provides excellent resistance to:
Atmospheric corrosion
Industrial environments
Marine conditions
Many chemical media
The high purity minimizes galvanic corrosion risks, making it ideal for chemical and outdoor applications.
High Electrical and Thermal Conductivity of 1050 Aluminum Plate
| Property | Typical Value |
|---|---|
| Electrical Conductivity | ~61% IACS |
| Thermal Conductivity | ~222 W/m·K |
1050 aluminum sheet outperforms 1100 in conductivity and is often used as a cost-effective alternative to copper in suitable electrical and thermal applications.
Excellent Formability and Workability of 1050 Aluminum Sheet
Especially in the O (annealed) temper, 1050 aluminum plate is extremely soft and ductile, making it ideal for:
Deep drawing
Metal spinning
Bending and stamping
Complex shaping without cracking
It can be machined (with sharp tooling) and is easily welded using TIG, MIG, resistance welding, and other standard methods.
High Reflectivity and Surface Finish
1050 aluminum plate and sheet provide excellent reflectivity for both visible light and radiant heat. The clean, silvery surface also responds exceptionally well to:
Polishing
Chemical brightening
Anodizing
This makes it a preferred material for decorative, lighting, and architectural applications.
Non-Toxic and Hygienic Characteristics
Due to its chemical inertness, 1050 aluminum sheet is perfectly safe for:
Food contact
Pharmaceutical equipment
Brewing and distilling systems
It does not impart taste, odor, or contamination.
Key Tempers of 1050 aluminum plate
The performance of 1050 aluminum sheet and plate can be adjusted through cold working.
| Temper | Description | Typical Use |
|---|---|---|
| O (Annealed) | Softest state, maximum ductility | Deep drawing, spinning |
| H14 | Half-hard, balanced strength and formability | General sheet metal |
| H18 | Full-hard, maximum strength | Flat components, minimal forming |
