Aluminum sheets are among the most versatile and widely used materials in the world today. These sheets come in a variety of grades and alloys, each with its unique properties and characteristics. Two of the most commonly used aluminum sheet grades are the 1050 and 1070 alloys. In this article, we’ll compare and contrast these two alloys to help you understand the differences and choose the right one for your application.
1050 Aluminum Sheet:
1050 aluminum sheet is a pure aluminum alloy, meaning it contains no other elements besides aluminum. It is soft, ductile, and has excellent workability, making it easy to form into a variety of shapes and sizes. This alloy is commonly used in the manufacturing of heat exchangers, evaporators, and other similar applications where high thermal conductivity and corrosion resistance are essential. It is also frequently used in the printing industry for lithographic plates.
1070 Aluminum Sheet:
1070 aluminum sheet is also a pure aluminum alloy, but with slightly different properties than the 1050 grade. It is slightly stronger and has better corrosion resistance, making it a popular choice for applications that require these properties. This alloy is commonly used in the electrical industry for transformer and capacitor components, as well as in the automotive industry for radiators, condensers, and other similar applications.
1050 Aluminum Sheet VS 1070 Aluminum Sheet:
While both 1050 and 1070 aluminum sheets are pure aluminum alloys, there are a few key differences between them. The 1050 alloy is softer and more ductile, making it easier to form and shape. It also has a slightly lower melting point than the 1070 alloy. However, the 1070 alloy is slightly stronger and has better corrosion resistance than the 1050 alloy, making it better suited for certain applications.
When it comes to thermal conductivity, both alloys are relatively similar, with the 1050 alloy having a thermal conductivity of 229 W/mK and the 1070 alloy having a thermal conductivity of 201 W/mK. Both alloys are also highly conductive electrically, making them suitable for electrical applications.
In conclusion, both 1050 and 1070 aluminum sheets have their unique properties and characteristics, making them suitable for different applications. The 1050 alloy is softer and more ductile, making it easier to form and shape, and is commonly used in heat exchangers, evaporators, and lithographic plates. The 1070 alloy is slightly stronger and has better corrosion resistance, making it a popular choice for transformer and capacitor components, as well as in the automotive industry for radiators and condensers. Choosing the right alloy will depend on the specific application and the properties required for that application.
