На додаток, it also contains a certain amount of manganese (Мн), хром (Cr), мідь (Куточок), цинк (Zn), titanium (На) and other elements, as well as a small amount of conductive materials and lead (Pb) and bismuth (Bi) added to improve processing performance.

The specific composition ratio may be adjusted according to production needs, but usually the Mg content is between 0.8% і 1.2%, and the Si content is between 0.4% і 0.8%.

The specific chemical composition (in percentage) на 6061 алюмінієвий сплав is roughly: алюміній (remainder), кремнію (0.4~0.8%), мідь (0.15~0.4%), магній (0.8~ 1,2%), цинк (≤0.25%), марганець (≤0.15%), хром (0.04~0.35%), titanium (≤0.15%), прасувати (≤0.7%).

6063 алюмінієвий сплав

Also contains magnesium (Мг) і кремнію (І), but the content is relatively low.

Конкретно, the Mg content is usually between 0.45% і 0.9%, and the Si content is between 0.2% і 0.6%.

На додаток, it also contains a small amount of copper (Куточок), цинк (Zn), марганець (Мн), titanium (На), хром (Cr) and iron (Феод).

The specific chemical composition (in percentage) на 6063 aluminum alloy is roughly: алюміній (remainder), кремнію (0.2~ 0,6%), мідь (≤0.1%), магній (0.45~0.9%), цинк (≤0.1%), марганець (≤0.1%), titanium (≤0.1%), хром (≤0.1%), прасувати (≤0.35%).

2. Механічні властивості 6061 проти 6063 Алюмінієвий сплав

6061 алюмінієвий сплав

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 алюмінієвий сплав

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

Це робить 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 алюмінієвий сплав

Due to its high strength, Хороша зварюваність, і корозійна стійкість, this material is widely used in trucks, ships, aerospace devices, trams, форми, електроніка, меблі, and corrosion-resistant structures.

6063 алюмінієвий сплав

It has high strength, Опір зносу, 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.

На додаток, it is also commonly used in rail transportation, аерокосмічний, military equipment, automated conveying equipment and other fields.

4. Heat treatment process of 6061 проти 6063 Алюмінієвий сплав

6061 алюмінієвий сплав

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 алюмінієвий сплав

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.

Однак, 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. Висновок

There are significant differences between 6061 проти 6063 aluminum alloy in chemical composition, механічні властивості, scope of use and heat treatment process.

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