6063 aluminiumlegering

Also contains magnesium (Mg) en silicium (En), but the content is relatively low.

Specifiek, the Mg content is usually between 0.45% En 0.9%, and the Si content is between 0.2% En 0.6%.

In aanvulling, it also contains a small amount of copper (Cu), zink (Zn), mangaan (Mn), titanium (Van), chroom (Cr) en ijzer (Fe).

The specific chemical composition (in percentage) van 6063 aluminum alloy is roughly: aluminium (remainder), silicium (0.2~ 0,6%), koper (≤0.1%), magnesium (0.45~0.9%), zink (≤0.1%), mangaan (≤0.1%), titanium (≤0.1%), chroom (≤0.1%), ijzer (≤0,35%).

2. Mechanical properties of 6061 vs 6063 Aluminiumlegering

6061 aluminiumlegering

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 aluminiumlegering

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

Dit maakt 6063 aluminum alloy more advantageous in applications that require high precision and complex shapes.

Tegelijkertijd, 6063 aluminum alloy also has high tensile strength and yield strength.

3. Scope of use

6061 aluminiumlegering

Due to its high strength, Goede lasbaarheid, en corrosieweerstand, this material is widely used in trucks, ships, aerospace devices, trams, schimmels, elektronica, meubilair, and corrosion-resistant structures.

6063 aluminiumlegering

It has high strength, Draag weerstand, 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.

In aanvulling, it is also commonly used in rail transportation, ruimtevaart, militaire uitrusting, automated conveying equipment and other fields.

4. Heat treatment process of 6061 vs 6063 Aluminiumlegering

6061 aluminiumlegering

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 aluminiumlegering

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.

Echter, 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. Conclusie

There are significant differences between 6061 vs 6063 aluminum alloy in chemical composition, mechanische eigenschappen, scope of use and heat treatment process.

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