The Difference Between 6061 Aluminum and 6063 Aluminum

Chemical composition: 6061 aluminum alloy has a higher silicon content, lower copper content, and a higher proportion of magnesium element; And 6063 aluminum alloy has a lower silicon content and a higher copper content, with the main alloying elements being magnesium and silicon.

Mechanical properties: Due to the high proportion of alloying elements in 6061 aluminum alloy, it has high strength and hardness; And 6063 aluminum alloy is relatively soft, with good ductility and machinability. Therefore, in situations where high strength and hardness are required, 6061 aluminum alloy is more suitable; In situations where good plasticity and processing performance are required, 6063 aluminum alloy is more suitable. twelve

Heat treatment ability: 6061 aluminum alloy has good heat treatment ability and can achieve high strength through heat treatment; However, the heat treatment ability of 6063 aluminum alloy is relatively poor, and the heat treatment effect is not as significant as 6061 aluminum alloy.

Application field: 6061 aluminum alloy is commonly used in aerospace, automotive manufacturing, bicycle components, and other applications that require high load and strength requirements; 6063 aluminum alloy is commonly used in building materials, door and window frames, exhibition displays, and other applications that require good appearance and processing performance.

Surface treatment: 6061 aluminum alloy is usually treated by anodizing and other methods to improve corrosion resistance and appearance quality; 6063 aluminum alloy, on the other hand, usually adopts surface treatment methods such as color electrophoresis and powder coating to improve appearance and enhance oxidation resistance.

In summary, there are differences between 6063 aluminum and 6061 aluminum in terms of chemical composition, strength, mechanical properties, processability, and corrosion resistance. According to the specific application requirements, corresponding aluminum materials can be selected to meet the required performance requirements.
