1100 aluminum alloy is an industrial pure aluminum with an aluminum content of 99.00%. This alloy does not possess the ability to be strengthened through heat treatment, but it performs excellently in other aspects.
1100 aluminum alloy is widely used in various industrial fields due to its excellent corrosion resistance, electrical conductivity, thermal conductivity, and good formability. However, because of its lower strength, it is suitable for applications with low strength requirements.
1100 aluminum sheet and strip belongs to the pure aluminum sheet series, and its strength is relatively low. After anodizing, the corrosion resistance can be further improved, and a beautiful surface can be obtained.
Advantages
Disadvantages
Due to its low tensile strength and softness, 1100 aluminum sheet is not used for high strength or high pressure applications.
