The difference of 6061 vs 6063 aluminum alloys are different chemical compositions, mechanical properties, application range and heat treatment process. Although the strength of 6061 aluminum alloy cannot be compared with that of 2XXX series or 7XXX series aluminum alloy, its magnesium and silicon alloys have many characteristics, It has excellent processing performance, excellent welding characteristics and electroplating, good corrosion resistance, high toughness and no deformation after processing, dense material without defects and easy to polish, easy to color film, excellent oxidation effect and other excellent characteristics. 6063 aluminum alloy is a heat-treatable strengthening alloy with moderate strength in the AL-Mg-Si series. Mg and Si are the main alloying elements. The main work of optimizing the chemical composition is to determine the percentage content of Mg and Si.
The detailed difference of aluminum 6061 vs 6063 are:
1, Different chemical composition
6061 aluminum alloy has more alloying elements than 6063 aluminum alloy. The main alloying elements of 6063 aluminum alloy are magnesium and silicon.
2, Mechanical properties
6061 grade aluminum alloy are better than 6063 aluminum alloy in terms of strength and machinability, and also have good oxidation resistance. But in terms of plasticity, 6063 aluminum alloy is better, it can make the material achieve higher precision; 6063 aluminum alloy has higher tensile strength and yield strength, showing better fracture toughness.
3, Use scope of al 6061 vs 6063
6061 aluminum alloy is a high-quality aluminum alloy material with high toughness, good weldability and corrosion resistance, which can be used in trucks, ships, aerospace installations, trucks, trams, molds, electronics, furniture, corrosion resistance structure.While 6063 is an aluminum alloy material with very strong comprehensive properties. It has high strength, wear resistance, corrosion resistance and high temperature resistance. It can be used for building profiles and industrial profiles at the same time. Commonly used in construction aluminum alloy doors and windows, curtain walls, various industrial frame structures, rail transit, aerospace, military equipment, automated conveying equipment and other fields.
4, Heat treatment process of 6061 vs 6063
6061 aluminum alloy is no longer cold processed after solid solution heat treatment, and can be naturally aged (T4 state), or directly artificially aged, that is, T6 state, 6061 t6 aluminum plate has a large deformation coefficient, high hardness, and is not easy to control; Re-cooling, that is, the quenching process, generally adopts the cooling method of air cooling, and then undergoes artificial aging treatment, that is, the T5 state. It can eliminate the internal stress of industrial aluminum to the greatest extent, the deformation coefficient is small, the hardness is not so high, it will not break easily, and the mechanical properties are stronger, but 6063 also adopts the T6 treatment method, and its deformation coefficient will also become larger. , the hardness is higher, and the fracture phenomenon is more likely to occur than T5.
