Mga Pangunahing Pagkakaiba sa Mga Katangian
- Lakas ng loob:
- 7075 Aluminyo ay mas malakas, may lakas ng paghatak ng 572 MPa kumpara sa 310 MPa para sa 6061-T6. Ito ay gumagawa ng 7075 aluminyo mainam para sa mataas na stress istruktura application.
- Paglaban sa kaagnasan:
- 6061-T6 Aluminum ay may mahusay na paglaban sa kaagnasan, lalo na laban sa atmospheric at marine kondisyon, habang ang 7075 Aluminyo has fair to poor corrosion resistance and often requires a protective coating or anodizing for use in corrosive environments.
- Weldability:
- 6061-T6 Aluminum is highly weldable, making it suitable for structures requiring frequent welding. 7075 Aluminyo is difficult to weld and can suffer from cracking and brittleness after welding.
- Machinability:
- 6061-T6 Aluminum is known for its good machinability, which is better than that of 7075 Aluminyo, although 7075 still offers acceptable machinability for most applications.
- Densidad ng katawan:
- 7075 Aluminyo is slightly denser (2.81 g/cm³) than 6061-T6 Aluminum (2.70 g/cm³), which can affect weight-sensitive applications.
- Thermal kondaktibiti:
- 6061-T6 Aluminum has better thermal conductivity (167 W/m·K) compared to 7075 Aluminyo (130 W/m·K), making it preferable for heat-exchange applications.
Comparison of Uses
