Key Differences in Properties

  1. Strength:
    • 7075 Alüminium is much stronger, with a tensile strength of 572 MPa compared to 310 MPa for 6061-T6. This makes 7075 aluminum ideal for high-stress structural applications.
  2. Korroziyaya davamlılıq:
    • 6061-T6 Alüminium əla korroziya müqavimətinə malikdir, especially against atmospheric and marine conditions, while 7075 Alüminium has fair to poor corrosion resistance and often requires a protective coating or anodizing for use in corrosive environments.
  3. Qaynaq qabiliyyəti:
    • 6061-T6 Alüminium is highly weldable, making it suitable for structures requiring frequent welding. 7075 Alüminium is difficult to weld and can suffer from cracking and brittleness after welding.
  4. İşlənmə qabiliyyəti:
    • 6061-T6 Alüminium is known for its good machinability, which is better than that of 7075 Alüminium, although 7075 still offers acceptable machinability for most applications.
  5. Sıxlıq:
    • 7075 Alüminium is slightly denser (2.81 q/sm³) than 6061-T6 Alüminium (2.70 q/sm³), which can affect weight-sensitive applications.
  6. İstilik keçiriciliyi:
    • 6061-T6 Alüminium has better thermal conductivity (167 W/m·K) compared to 7075 Alüminium (130 W/m·K), making it preferable for heat-exchange applications.
