4000 series aluminum coil density

The density of aluminum alloys may vary depending on the specific alloy composition and the heat treatment process it undergoes. The 4000 series aluminum alloy is a typical aluminum-silicon alloy. The characteristics of the 4000 series aluminum alloy include good corrosion resistance and good welding performance.

Common 4000 series aluminum alloys mainly include 4043 4047 4145 aluminum coil

4043 alloy: Contains 5% silicon, commonly used in argon arc welding of aluminum alloys. Suitable for welding cast aluminum alloys, connections between cast aluminum alloys and wrought aluminum alloys.

4047 alloy: contains 12% silicon, often used in argon arc welding, especially for the connection between aluminum alloy and cast iron.

4145 alloy: contains 11% silicon, suitable for gas welding and argon arc welding.

Aluminum-silicon alloys within the 4000 series may have densities similar to pure aluminum, but may vary slightly depending on the specific alloy and its composition.
