A7, A8, A9 aluminum ingots are internationally recognized grades used to differentiate aluminum materials with different purities and compositions.

Standard: ASTM, GB, DIN, BS, EN, JIS
















Type
Describe




A7 aluminum ingot
A7 aluminum ingot is a high-purity aluminum ingot typically with aluminum purity of 99.7% or higher. It has relatively high purity and is commonly used in the production of aluminum alloy materials, aluminum sheets, aluminum profiles, etc.


A8 aluminum ingot
A8 aluminum ingot is an aluminum alloy ingot typically with aluminum purity of 99.8% or higher, along with a small amount of alloying elements such as copper, manganese, etc. It has higher strength and corrosion resistance and is commonly used in automotive parts, aerospace, construction, etc.


A9 aluminum ingot
A9 aluminum ingot is an aluminum alloy ingot typically with aluminum purity of 99.9% or higher, along with a certain proportion of alloying elements such as copper, manganese, magnesium, etc. It has higher strength and corrosion resistance and is commonly used in aerospace, automotive parts, construction, electronics, etc.

Application



Ordinary industrial pure aluminum is thought as 1000 series aluminum ingot, aluminum content upto 99.0%. Low strength, heat treatment canâ??t be further strengthened; But it is very malleable. Aluminum products have good corrosion resistance and weldability; After anodic oxidation, thecorrosion resistance of aluminum ingot are often improved, and a more beautiful surface layer can beobtained.
