1050 Aluminum Disc
When manufacturers need a soft, formable, and corrosion-resistant aluminum blank, 1050 aluminum disc is one of the most practical choices. It is widely supplied for cookware, lighting parts, signs, electrical parts, spinning parts, and deep drawing applications.
1050 aluminum belongs to the commercially pure aluminum family. It contains at least 99.50% aluminum. This gives it excellent formability, high thermal conductivity, high electrical conductivity, and good surface quality.
This guide explains what 1050 aluminum disc is, its chemical composition, density, mechanical properties, standard sizes, applications, price factors, and how to choose reliable 1050 aluminum suppliers.
1. What Is 1050 Aluminum Disc?
A 1050 aluminum disc is a round aluminum blank cut from 1050 aluminum sheet or coil. It is also called:
- Aluminum disc
- Aluminum circle
- Aluminium disc
- Aluminium circle
- Round aluminum blank
- Deep drawing aluminum disc
The disc shape makes it easy to process by stamping, spinning, deep drawing, polishing, or anodizing. For this reason, 1050 aluminum discs are common in cookware and lighting industries.
1050 aluminum is not heat-treatable. Its strength comes from cold working. Its main advantage is not high strength. Its advantage is excellent forming performance and clean surface quality.
2. 1050 Aluminum Composition
The key feature of 1050 aluminum is high aluminum purity. The typical 1050 aluminum composition is shown below.
| Element | Content (%) | Role | Why It Matters |
|---|---|---|---|
| Aluminum (Al) | ≥ 99.50 | Base metal | Gives high formability, conductivity, and corrosion resistance |
| Iron (Fe) | ≤ 0.40 | Controlled impurity | Affects ductility and surface quality |
| Silicon (Si) | ≤ 0.25 | Controlled impurity | Influences hardness and forming behavior |
| Copper (Cu) | ≤ 0.05 | Controlled impurity | Kept low for corrosion resistance |
| Manganese (Mn) | ≤ 0.05 | Controlled impurity | Kept low to maintain purity |
| Magnesium (Mg) | ≤ 0.05 | Controlled impurity | Low level keeps alloy soft and formable |
| Zinc (Zn) | ≤ 0.05 | Controlled impurity | Controlled for corrosion stability |
| Titanium (Ti) | ≤ 0.03 | Grain refiner | Helps improve grain structure |
| Others | ≤ 0.03 each | Trace elements | Controlled for consistent quality |
The high aluminum content gives 1050 aluminum discs excellent ductility. This is important for deep drawing and spinning, where the metal must flow without cracking.
3. 1050 Aluminum Density and Physical Properties
The 1050 aluminum density is about 2.70 g/cm³. This is much lighter than steel and close to other commercially pure aluminum grades.
| Property | Typical Value |
|---|---|
| Density | 2.70 g/cm³ |
| Melting range | Approx. 646–657°C |
| Elastic modulus | 69 GPa |
| Thermal conductivity | 222–235 W/m·K |
| Electrical conductivity | About 61% IACS |
| Thermal expansion | 23.6 × 10⁻⁶ /K |
| Specific heat | 0.90 kJ/kg·K |
These properties make 1050 aluminum suitable for cookware, heat transfer parts, reflectors, nameplates, and electrical components.
4. Mechanical Properties by Temper
1050 aluminum disc is available in several tempers. The right temper depends on the forming method and final application.
| Temper | Tensile Strength | Yield Strength | Elongation | Typical Use |
|---|---|---|---|---|
| O | 65–95 MPa | 20–35 MPa | 25–40% | Deep drawing, spinning, cookware |
| H12 | 80–120 MPa | 60–90 MPa | 8–15% | Light forming, general parts |
| H14 | 95–135 MPa | 75–110 MPa | 4–10% | Stamping, lids, signs |
| H16 | 110–145 MPa | 95–125 MPa | 3–7% | Stiffer parts |
| H18 | 120–160 MPa | 110–145 MPa | 2–5% | Flat parts, limited forming |
For deep drawing cookware, 1050-O aluminum disc is usually preferred. It is soft and has high elongation. For lids, signs, and shallow stamping parts, H14 or H16 can be selected.
5. 1050 Aluminum Sheet and Disc Production
A 1050 aluminum disc is usually produced from 1050 aluminum sheet or aluminum coil.
The common production process includes:
- Casting aluminum ingot
- Hot rolling or continuous casting
- Cold rolling to target thickness
- Annealing or temper control
- Leveling and cleaning
- Circle blanking or punching
- Edge trimming and deburring
- Surface inspection
- Packing for shipment
The quality of the 1050 aluminum sheet directly affects the final disc. Good sheet material gives better flatness, cleaner surface, and lower cracking risk during forming.
6. Standard Sizes of 1050 Aluminum Disc
1050 aluminum discs are available in many diameters and thicknesses. Custom sizes are also common.
