Aluminium 5083 vs 1050 – What’s the Difference

Aluminium 5083 vs 1050

Aluminium is a widely used metal in the fabrication industry. Its unique characteristics, such as light, corrosion-resistant, and strong, make it the material of choice in various manufacturing applications. Aluminium is available in different grades, each with specific properties and uses. This blog post will compare Aluminium 5083 and Aluminium 1050, two common grades used in the industry. We will highlight their differences, properties, and applications to help you understand which is best suited for your project.

What is Aluminium 5083?

Aluminium 5083 is an alloy of Aluminium, magnesium and manganese. It is exceptionally strong, with excellent corrosion resistance and weldability. It also has good machinability, providing a high strength-to-weight ratio with a low thermal expansion rate, making it great for use in the automotive industry for body panels and structural components. Additionally, Aluminium 5083 is widely used in marine applications such as boat building due to its superior resistance to saltwater corrosion and weathering characteristics. Its versatility extends into architectural buildings and antenna towers where strength and lightness are desired features in construction materials.

What is Aluminium 1050?

Aluminium 1050 is a commercially pure aluminium alloy comprised of 99.5% aluminium. This high-grade alloy is highly resistant to corrosion and oxidation, providing excellent electrical conductivity, formability, and weldability. It offers good ductility, providing greater flexibility in design than other alloys such as 3003 or 5052, making it ideal for industrial applications like electronic components, impact extrusions and so on.

Difference Between Aluminium 5083 and 1050

Aluminium 5083 and 1050 are both aluminium alloys. However, they have some distinct differences. 5083 is more corrosion resistant and has higher tensile strength and yield strength than 1050 (more suitable for tough applications). Also, while they share a similar density (2.7 g/cm3), the thermal conductivity 5083 is higher than that of 1050 by approximately 10%. Consequently, this makes it an optimal choice for many heat-transfer applications.


Aluminium 5083 is an alloy composed of magnesium, manganese, chromium, and traces of other elements. This alloy is commonly used in marine environments due to its high resistance to saltwater corrosion. On the other hand, Aluminium 1050 is a pure grade with a minimum Aluminium content of 99.5%. Pure Aluminium is soft and has excellent flexibility, which makes it easier to form into different shapes.

Strength and Mechanical Properties

Aluminium 5083 has a higher tensile strength than 1050, making it stronger and more durable. It also has better corrosion resistance, particularly in harsher environments such as seawater exposure. However, 1050 possesses excellent electrical and thermal conductivity, making it an excellent choice for electrical applications.


Aluminium 5083 and 1050 have different applications due to their varying properties. 5083 is widely used in structural and construction applications, especially in the marine industry, as it has excellent corrosion resistance to salt water and is incredibly durable. Due to its high strength is also often used in manufacturing transport vehicles, such as trucks and trailers. Due to its high electrical conductivity, 1050 is often used in electrical applications such as transformer windings and heat exchangers.


Machinability refers to how easily a material can be machined into different shapes or components. Aluminium 5083 is harder than 1050, which makes it more challenging to machine, but perfect for deep drawing or extrusion. In comparison, 1050 is much softer and more ductile, which makes it an ideal material for forming into different shapes and components.


Aluminium 1050 is relatively inexpensive compared to 5083. However, due to its unique properties, 5083 is more expensive and commonly used in critical applications, such as marine and aircraft manufacturing.


In conclusion, Aluminium 5083 and 1050 grades have different properties, applications, and costs. 5083 is ideal for use in harsh environments where resistance to corrosion and strength is critical, such as in marine applications. In contrast, 1050 is perfect for applications where electrical conductivity, flexibility, and cost are essential factors. It is essential to clearly understand the properties of different Aluminium grades to choose the one that suits your project needs.
