6063 سبيكة الألومنيوم

Also contains magnesium (ملغ) وسيليكون (و), but the content is relatively low.

خاصة, the Mg content is usually between 0.45% و 0.9%, and the Si content is between 0.2% و 0.6%.

فضلاً عن ذلك, it also contains a small amount of copper (النحاس), الزنك (Zn), المنغنيز (MN), titanium (ل), الكروم (كر) والحديد (Fe).

The specific chemical composition (in percentage) ل 6063 aluminum alloy is roughly: الألومنيوم (remainder), السيليكون (0.2~ 0.6 ٪), نحاس (≤0.1 ٪), المغنيسيوم (0.45~0.9%), الزنك (≤0.1 ٪), المنغنيز (≤0.1 ٪), titanium (≤0.1 ٪), الكروم (≤0.1 ٪), حديد (≤0.35%).

2. الخصائص الميكانيكية من 6061 مقابل 6063 سبيكة الألومنيوم

6061 سبيكة الألومنيوم

It has high strength and cutting performance, and has good oxidation resistance.

Its tensile strength and yield strength are relatively high, but its plasticity is relatively poor.

6063 سبيكة الألومنيوم

Although its strength is slightly lower than that of 6061, it has higher plasticity and better fracture toughness.

هذا يجعل 6063 aluminum alloy more advantageous in applications that require high precision and complex shapes.

At the same time, 6063 aluminum alloy also has high tensile strength and yield strength.

3. Scope of use

6061 سبيكة الألومنيوم

Due to its high strength, قابلية اللحام الجيدة, ومقاومة التآكل, this material is widely used in trucks, ships, aerospace devices, trams, قوالب, الإلكترونيات, أثاث, and corrosion-resistant structures.

6063 سبيكة الألومنيوم

It has high strength, ارتداء المقاومة, corrosion resistance and high temperature resistance, and can be used for building profiles and industrial profiles.

In particular, its good extrusion and corrosion resistance make it the preferred material for building aluminum alloy doors and windows, curtain walls and various industrial frame structures.

فضلاً عن ذلك, it is also commonly used in rail transportation, الفضاء, military equipment, automated conveying equipment and other fields.

4. Heat treatment process of 6061 مقابل 6063 سبيكة الألومنيوم

6061 سبيكة الألومنيوم

After solution heat treatment, you can perform natural aging (T4 state) or direct artificial aging (T6 state) without cold processing.

Its deformation coefficient is large, hardness is high, and it is difficult to control.

6063 سبيكة الألومنيوم

After high-temperature forming, it is cooled (quenching process), generally using air cooling method, and then artificial aging treatment (T5 state).

This treatment method can eliminate internal stress to the greatest extent, making the deformation coefficient small, the hardness moderate, and the mechanical properties stronger.

لكن, 6063 aluminum alloy also adopts T6 treatment method, at which time its deformation coefficient will become larger and the hardness will be higher, but it is more likely to break than T5 state.

5. خاتمة

There are significant differences between 6061 مقابل 6063 aluminum alloy in chemical composition, الخصائص الميكانيكية, scope of use and heat treatment process.

لذلك, when selecting aluminum alloy materials, you should choose the appropriate model based on specific application requirements and working environment.
