是合金元素的不同，5052的合金元素是鎂，6061合金的元素除了鎂以外還含有硅。再就是加工狀態也不一樣，6061鋁板和5052鋁板二者除了都有o態意外，6061鋁板一般都是T6和T651狀態，5052鋁板一般都是H112、H24、H32狀態。
It is the difference of alloy elements. The alloy element of 5052 is magnesium, and the element of 6061 alloy contains silicon in addition to magnesium. Moreover, the processing status is also different. In addition to the o status of 6061 aluminum plate and 5052 aluminum plate, 6061 aluminum plate is generally in T6 and t651 status, and 5052 aluminum plate is generally in h112, H24 and H32 status.
加工狀態和合金元素的不同，讓這兩種鋁板從性能到用途也發生了區別，5052鋁板應用范圍較為廣泛，具有抗疲勞強度，塑性與耐腐蝕性高，不能熱處理強化，在半冷作硬化時塑性尚好，冷作硬化時塑性低，耐腐蝕好，焊接性良好，可切削性能不良，可拋光。6061鋁板良好的抗腐蝕性，可焊接性，氧化效果好．廣泛應用于要求有一定強度和抗蝕性高的各種工業結構件。6061鋁板多數用于對強度有較高要求的地方，5052鋁板屬于防銹鋁合金，多用于對有防銹需求的環境。
The different processing state and alloy elements make the two aluminum plates different from each other in performance and application. 5052 aluminum plate has a wide range of applications, with fatigue strength, high plasticity and corrosion resistance, and can not be strengthened by heat treatment. It has good plasticity during semi cold work hardening, low plasticity during cold work hardening, good corrosion resistance, good weldability, poor machinability and polishing. 6061 aluminum plate has good corrosion resistance, weldability and good oxidation effect. It is widely used in various industrial structural parts requiring certain strength and high corrosion resistance. 6061 aluminum plate is mostly used in places with high requirements for strength, and 5052 aluminum plate is an anti rust aluminum alloy, which is mostly used in the environment with anti rust requirements.

5052鋁板力學性能抗拉強度 σb (MPa)：≤225 伸長率 δ5 (%)：≥10
5052 aluminum plate mechanical properties tensile strength σ B (MPA): ≤ 225 elongation δ 5 (%)：≥10
6061鋁板力學性能抗拉強度 σb (MPa)：≥180 屈服強度 σ0.2 (MPa)：≥110 伸長率 δ5 (%)：≥14
6061 aluminum sheet mechanical properties tensile strength σ B (MPA): ≥ 180 yield strength σ 0.2 (MPA): ≥ 110 elongation δ 5 (%)：≥14
5052鋁板可以折彎，6061鋁板由于硬度高，一般多用于磨具，二者都具有較好的氧化效果。6061鋁板比5052的要硬很多，但是5052的折彎性和可塑性要比6系的強很多，所以我們在實際應用時要進行區別對待。
5052 aluminum plate can be bent. 6061 aluminum plate is generally used for abrasives because of its high hardness. Both of them have good oxidation effect. 6061 aluminum plate is much harder than 5052, but the bending and plasticity of 5052 is much stronger than that of 6 series, so we should treat it differently in practical application.
