Aluminium is a cornerstone material in numerous industries due to its exceptional properties such as lightweight, high conductivity, and corrosion resistance. Among the various aluminium alloys available, grades 1050 and 1200 are prominent in applications requiring high purity and excellent formability. Despite their similarities, these two alloys have distinct characteristics that make them suitable for different applications. Understanding the differences between aluminium 1050 and 1200 is crucial for engineers, manufacturers, and designers to select the most appropriate material for their specific needs. This comprehensive analysis delves into the chemical compositions, mechanical properties, and typical applications of these two aluminium grades, providing insights into their unique advantages and limitations.
For industries looking to optimize their products with high-purity aluminium, the 1050 aluminum coil offers a blend of performance and versatility that is hard to match.
Aluminium alloys are formed by adding elements such as silicon, copper, magnesium, and zinc to pure aluminium to enhance its mechanical and physical properties. The Aluminium Association (AA) designates these alloys with a four-digit numerical system, where the first digit indicates the principal alloying element. The 1000 series, which includes both 1050 and 1200 alloys, represents commercially pure aluminium with a minimum of 99% aluminium content. These high-purity alloys are known for excellent corrosion resistance, thermal and electrical conductivity, and good formability, making them suitable for a wide range of applications.
Aluminium 1050 is a high-purity alloy containing a minimum of 99.5% aluminium. Its chemical composition is characterized by very low levels of other elements. The typical maximum percentages of impurities are:
The high aluminium content of 1050 alloy gives it excellent electrical and thermal conductivity, making it ideal for applications where these properties are critical.
Aluminium 1200 is another high-purity alloy with a minimum aluminium content of 99.0%. Its chemical composition includes slightly higher levels of impurities compared to 1050 alloy. The typical maximum percentages of impurities are:
While still considered a high-purity aluminium, the increased level of impurities in 1200 alloy slightly affects its conductivity but can enhance certain mechanical properties.
Aluminium 1050 is known for its excellent ductility and low mechanical strength. Its tensile strength typically ranges from 45 to 75 MPa, and it has a Brinell hardness of approximately 20 HB. This softness allows for easy forming and bending but limits its use in applications requiring higher strength.
In contrast, aluminium 1200, with its slightly higher impurity content, exhibits marginally increased mechanical strength. Its tensile strength ranges from 50 to 85 MPa, and it has a Brinell hardness of around 22 HB. This slight increase in strength can make 1200 alloy more suitable for certain structural applications.
Due to its higher aluminium purity, 1050 alloy boasts superior electrical and thermal conductivity. It has an electrical conductivity of approximately 61% IACS (International Annealed Copper Standard) and excellent thermal conductivity, making it ideal for electrical and thermal applications.
Aluminium 1200, while still offering good conductivity, falls slightly behind 1050 alloy. Its electrical conductivity is around 59% IACS. The marginal difference can be significant in applications where maximum conductivity is required.
Both alloys exhibit excellent formability due to their high ductility. Aluminium 1050, with its lower strength, can be easily formed into complex shapes through processes such as deep drawing and spinning. This makes it suitable for manufacturing items like lamp reflectors and chemical equipment.
Aluminium 1200 also offers good formability but with slightly better strength, which can be advantageous in applications requiring a balance between formability and mechanical strength. The weldability of both alloys is excellent, allowing for easy joining without compromising structural integrity.
One of the standout features of high-purity aluminium alloys is their excellent corrosion resistance. The protective oxide film that naturally forms on the surface of aluminium provides a barrier against moisture and chemicals. Both 1050 and 1200 alloys exhibit this property, making them suitable for applications in harsh environments.
However, the slightly higher impurity content in aluminium 1200 can result in minor differences in corrosion resistance, especially in more aggressive environments. In applications where maximum corrosion resistance is critical, aluminium 1050 may be the preferred choice.
Due to its high purity and excellent conductivity, aluminium 1050 is commonly used in applications such as:
Manufacturers often choose aluminium 1050 for products where excellent formability and high corrosion resistance are essential.
Aluminium 1200, with its balance of purity and slightly enhanced strength, is used in applications like:
Its combination of good formability and adequate strength makes aluminium 1200 suitable for products requiring reliable performance over time.
Both aluminium 1050 and 1200 alloys are available in various forms, including sheets, plates, coils, and foils. They can be supplied in different temper conditions to suit specific fabrication requirements. The 1050 aluminum coil, for example, is widely used in industries that require continuous processing and consistent material properties.
When comparing aluminium 1050 and 1200, the primary considerations revolve around purity, conductivity, mechanical strength, and corrosion resistance.

Aluminium 1050 was selected due to its superior conductivity, ensuring minimal energy losses and efficient performance. The choice of aluminium 1050 resulted in enhanced system efficiency and reduced operational costs.
An architectural firm sought a material for building facades that offered a balance between formability for aesthetic designs and strength for structural integrity. Aluminium 1200 was chosen for its adequate mechanical strength and excellent corrosion resistance, which is essential for outdoor applications. The use of aluminium 1200 allowed for creative freedom in design while ensuring long-term durability.
Aluminium is a highly sustainable material due to its recyclability. Both 1050 and 1200 alloys can be recycled repeatedly without loss of properties, contributing to environmental conservation and resource efficiency. The choice between the two alloys does not significantly impact environmental considerations, as both offer similar benefits in terms of recyclability and energy savings.
Cost is always a crucial factor in material selection. Generally, aluminium 1050 may be slightly more expensive due to its higher purity level. However, the cost difference is often justified by the superior properties it offers for specific applications. Aluminium 1200 provides a cost-effective alternative when slightly lower purity and conductivity are acceptable.
Understanding the subtle yet significant differences between aluminium 1050 and 1200 is essential for optimizing material selection in various industrial applications. Aluminium 1050, with its higher purity, offers superior electrical and thermal conductivity, making it ideal for applications where these properties are paramount.
