Introduction to Aluminium 1050 Plate and Aluminium 1200 Plate
Aluminium plays a vital role across numerous industries thanks to its lightweight nature, excellent corrosion resistance, and outstanding electrical and thermal conductivity. Within the 1000 series of aluminium alloys, Aluminium 1050 plate and Aluminium 1200 plate are two widely used grades, especially in applications that demand high purity and superior formability.
Although these two aluminium plates share many similarities, they differ in purity level, conductivity, mechanical strength, and typical end uses. Understanding the difference between Aluminium 1050 and Aluminium 1200 aluminium plates is essential for engineers, designers, and manufacturers aiming to select the most suitable material for performance, cost, and durability.
Overview of 1000 Series Aluminium Plates
The 1000 series aluminium alloys are classified as commercially pure aluminium, containing at least 99% aluminium. Alloys in this series, including Aluminium 1050 plate and Aluminium 1200 plate, are known for:
- Excellent corrosion resistance
- High electrical and thermal conductivity
- Very good formability and weldability
These properties make 1000 series aluminium plates ideal for electrical, chemical, architectural, and food-related applications.
Chemical Composition of Aluminium 1050 Plate vs Aluminium 1200 Plate
Aluminium 1050 Plate Chemical Composition
Aluminium 1050 aluminium plate contains a minimum of 99.5% aluminium, making it one of the highest-purity commercial aluminium grades. Impurity elements are strictly limited, which directly contributes to its superior conductivity.
Typical maximum composition:
Silicon (Si): 0.25
Iron (Fe): 0.40
Copper (Cu): 0.05
Manganese (Mn): 0.05
Magnesium (Mg): 0.05
Zinc (Zn): 0.07
Others (each): 0.03
Others (total): 0.10
Aluminium 1200 Plate Chemical Composition
Aluminium 1200 aluminium plate has a slightly lower minimum aluminium content of 99.0%. It allows a higher combined level of silicon and iron, which marginally affects conductivity while slightly improving strength.
Typical maximum composition:
Silicon + Iron (Si + Fe): 1.00
Copper (Cu): 0.05
Manganese (Mn): 0.05
Magnesium (Mg): 0.05
Zinc (Zn): 0.10
Others (each): 0.05
Others (total): 0.15
Mechanical Properties of Aluminium 1050 Plate and Aluminium 1200 Plate
Strength and Hardness Comparison
Aluminium 1050 plate is relatively soft and extremely ductile. Its typical tensile strength ranges from 45 to 75 MPa, with a Brinell hardness of around 20 HB. This makes it easy to bend, form, and deep draw, but limits its use in load-bearing applications.
Aluminium 1200 plate offers slightly higher mechanical strength due to its impurity content. Its tensile strength generally ranges from 50 to 85 MPa, with a Brinell hardness of approximately 22 HB, providing a modest improvement in rigidity while maintaining good formability.
Conductivity Performance of Aluminium 1050 Plate vs Aluminium 1200 Plate
Thanks to its higher purity, Aluminium 1050 aluminium plate delivers superior electrical and thermal conductivity, typically around 61% IACS.
Aluminium 1200 aluminium plate still performs well in conductivity-related applications but is slightly lower, at about 59% IACS. This difference can be important in applications where maximum efficiency is required.
Formability, Weldability, and Corrosion Resistance of Aluminium Plates
Both Aluminium 1050 and Aluminium 1200 plates offer excellent formability, making them suitable for spinning, bending, rolling, and deep drawing processes.
Aluminium 1050 plate is especially suitable for complex shapes due to its softness and high ductility.
Aluminium 1200 plate provides a better balance between formability and strength.
In terms of corrosion resistance, both aluminium plates perform exceptionally well due to the natural oxide layer on the surface. However, in highly aggressive environments, Aluminium 1050 plate may offer slightly better resistance because of its higher purity.
Typical Applications of Aluminium 1050 Plate
Because of its high purity and conductivity, Aluminium 1050 aluminium plate is commonly used in:
- Electrical conductors and busbars
- Heat exchangers and heat sinks
- Chemical processing equipment
- Food containers and packaging
- Reflectors and lighting components
Industries often choose Aluminium 1050 plate where conductivity, corrosion resistance, and ease of forming are critical.
Typical Applications of Aluminium 1200 Plate
With its combination of good strength and formability, Aluminium 1200 aluminium plate is widely used in:
- Heat exchangers and evaporators
- Architectural panels and building façades
- Industrial chemical equipment
- Printing plates
- Roofing, siding, and corrugated aluminium sheets

Cost and Availability of Aluminium 1050 Plate and Aluminium 1200 Plate
From an economic perspective, Aluminium 1050 plate is often slightly more expensive due to its higher purity. Aluminium 1200 plate provides a cost-effective alternative when marginally lower conductivity is acceptable.
Both aluminium plates are widely available in sheets, plates, coils, and foils and can be supplied in various temper conditions to suit different fabrication needs.
Conclusion: Choosing Between Aluminium 1050 Plate and Aluminium 1200 Plate
In summary, the difference between Aluminium 1050 and Aluminium 1200 aluminium plates lies primarily in purity, conductivity, and mechanical strength. Aluminium 1050 plate excels in applications where maximum electrical and thermal conductivity is required, while Aluminium 1200 plate offers a balanced solution with slightly higher strength and excellent formability.
The final choice should be based on application requirements, performance expectations, and budget considerations.
