Key Differences Between 1050 and 1060 Aluminum Plate-What Buyers Should Know
Choosing the right pure aluminum grade can significantly impact performance, cost, and service life. 1050 and 1060 aluminum plates are two of the most commonly used 1xxx series alloys. At GNEE, we help customers select the optimal aluminum sheet or plate based on real application requirements. Read on to understand the essential differences-and contact GNEE for tailored aluminum solutions.
Overview of 1050 vs 1060 Aluminum Plate Alloys
Both 1050 aluminum plate and 1060 aluminum plate belong to the 1xxx series, which is known for high aluminum purity (≥99%). While their chemical composition is very similar, small differences in purity lead to noticeable variations in strength, conductivity, corrosion resistance, and fatigue performance.
In general:
1050 aluminum sheet prioritizes formability and softness
1060 aluminum sheet offers higher strength and durability
Chemical Composition Difference Between 1050 and 1060 Aluminum Plate
| Element | 1050 Aluminum (%) | 1060 Aluminum (%) | Key Difference |
|---|---|---|---|
| Aluminum (Al) | 99.5–100 | 99.6–100 | 1060 has slightly higher purity |
| Copper (Cu) | ≤ 0.050 | ≤ 0.050 | Similar |
| Iron (Fe) | ≤ 0.40 | ≤ 0.35 | Lower Fe in 1060 |
| Magnesium (Mg) | ≤ 0.050 | ≤ 0.030 | Lower Mg in 1060 |
| Manganese (Mn) | ≤ 0.050 | ≤ 0.030 | Slightly purer 1060 |
| Silicon (Si) | ≤ 0.25 | ≤ 0.25 | Same |
| Zinc (Zn) | ≤ 0.050 | ≤ 0.050 | Same |
Key takeaway:
The higher aluminum content of 1060 aluminum plate contributes to better conductivity and corrosion resistance.
Mechanical Properties of 1050 vs 1060 Aluminum Sheet
| Property | 1050 Aluminum | 1060 Aluminum | Comparison |
|---|---|---|---|
| Tensile Strength (UTS) | 11–20 ksi | 9.7–18 ksi | 1050 slightly softer |
| Yield Strength | 3.7–18 ksi | 2.4–16 ksi | 1060 more stable |
| Elongation | 4.6–37% | 1.1–30% | 1050 more ductile |
| Fatigue Strength | 4.5–8.3 ksi | 2.2–7.3 ksi | 1060 more fatigue-resistant |
| Hardness | Lower | Slightly higher | 1060 is harder |
Conclusion:
1060 aluminum plate provides better strength and fatigue resistance, while 1050 aluminum sheet excels in flexibility and ease of forming.
Electrical & Thermal Conductivity Comparison
| Property | 1050 Aluminum | 1060 Aluminum |
|---|---|---|
| Electrical Conductivity (% IACS, volume) | 61 | 62 |
| Electrical Conductivity (% IACS, weight) | 200 | 210 |
| Thermal Conductivity (BTU/h-ft-°F) | 130 | 140 |
Main difference:
1060 aluminum sheet performs slightly better in electrical and thermal transfer due to higher purity.
Corrosion Resistance of 1050 vs 1060 Aluminum Plate
1050 aluminum plate: Excellent resistance in general and mildly corrosive environments
1060 aluminum plate: Superior resistance, better suited for industrial and marine conditions
Winner: 1060 aluminum for harsh environments
Formability of 1050 vs 1060 Aluminum Sheet
1050 aluminum: Extremely easy to form, ideal for deep drawing and complex shapes
1060 aluminum: Still highly formable, but marginally stiffer
Best choice for forming: 1050 aluminum sheet
Weldability of 1050 and 1060 Aluminum Plate
Both alloys feature excellent weldability. However, due to its softer structure, 1050 aluminum is slightly easier to weld than 1060.
Thermal Properties of 1050 vs 1060 Aluminum Plate
| Property | 1050 | 1060 |
|---|---|---|
| Melting Point (°F) | 1190 | 1210 |
| Specific Heat Capacity | 0.22 BTU/lb-°F | 0.22 |
| Thermal Expansion | 24 µm/m-K | 24 |
| Thermal Diffusivity | 94 mm²/s | 96 mm²/s |
Typical Applications of 1050 Aluminum Plate
1050 aluminum sheet is commonly used where strength is not critical but formability and corrosion resistance are essential:
Heat exchangers & radiators
Electrical conductors
Chemical equipment
Cookware & kitchenware
Decorative panels
Typical Applications of 1060 Aluminum Plate
1060 aluminum sheet is preferred when slightly higher strength and durability are required:
Electrical cables and busbars
Solar panel components
Chemical tanks
Heat exchangers
Medium-stress industrial parts
Summary: 1050 Aluminum Plate vs 1060 Aluminum Plate
Choose 1050 aluminum sheet for superior formability and softness
Choose 1060 aluminum plate for higher strength, conductivity, and corrosion resistance
Both alloys offer excellent weldability and wide industrial usability
