China 6061 aluminum plate contains more alloying elements compared to China 6063 aluminum plate.
The main alloying elements in China 6063 aluminum plate are magnesium and silicon.
China 6061 aluminum plate performs better in terms of strength and cutting machining properties compared to China 6063 aluminum plate and both possess good oxidation resistance. However, in terms of plasticity, the China 6063 aluminum plate excels as it can enable materials to achieve higher precision. The China 6063 aluminum plate has higher tensile strength and yield strength, exhibiting better fracture toughness.
China 6061 aluminum plate is a high-quality aluminum alloy material with high toughness, good weldability, and corrosion resistance. It can be used in heavy trucks, ships, aerospace devices, trucks, trams, molds, electronics, furniture, and corrosion-resistant structures;
China 6063 aluminum plate is a highly versatile aluminum alloy material with high strength, wear resistance, corrosion resistance, and heat resistance. It can be used both in architectural profiles and industrial profiles. It is commonly used in building aluminum doors and windows, curtain walls, various industrial frame structures, rail transit, aerospace, military equipment, and automation conveying equipment.
China 6061 aluminum plate does not undergo cold working after solid solution heat treatment and can be naturally aged (T4 state) or directly artificially aged, which is the T6 state. It has a larger deformation coefficient and higher hardness, making it difficult to control.
In contrast, China 6063 aluminum plate is formed at high temperature and then cooled, which is the quenching process, generally using air cooling. It is then subjected to artificial aging treatment, i.e., T5 state. This can maximize the elimination of internal stress in industrial aluminum profiles, with a smaller deformation coefficient and lower hardness, making it less prone to cracking and mechanically stronger.
However, China 6063 aluminum plate can also be treated using the T6 method, resulting in a larger deformation coefficient and higher hardness, making it more prone to cracking than in the T5 state.
