6063 aluminum coil is a recyclable material that meets the requirements of environmental protection and sustainable development. It has good corrosion resistance and can adapt to various complex environmental conditions, such as acid-base environment, humid environment, etc. At the same time, the welding performance is better and the production efficiency is improved. Its surface can also be subjected to surface treatment operations such as anodizing and painting, which improves the aesthetics and durability of the product.

Its common states include O state, T4, T5, T6, etc. These states represent different heat treatments and mechanical properties respectively.

• O state: This is the state of natural aging after solid solution heat treatment, and is suitable for products that have increased strength through cold processing. It has low hardness, good cutting force and fatigue resistance.
• T4 state: This is a state that is naturally aged to a basically stable state after solid solution heat treatment. It is suitable for products that will no longer be cold processed after solid solution heat treatment. It has low hardness, good cutting force and fatigue resistance.
• T5 state: This is the state of artificial aging after cooling by high-temperature molding process. It is suitable for products that are artificially aged after cooling by high-temperature molding process without cold processing. It has low hardness, good cutting force and fatigue resistance.
• T6 state: This is the state of artificial aging after solution heat treatment. It is suitable for products that will not be cold processed after solution heat treatment. It has high hardness, good fatigue strength and cutting force.

In general, aluminum coils in different states have different mechanical properties and applicable scenarios, and need to be selected according to specific needs.
