Key Differences in Properties

  1. Strength:
    • 7075 Alumini 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. Rezistenca ndaj korrozionit:
    • 6061-T6 Alumini ka rezistencë të shkëlqyer ndaj korrozionit, especially against atmospheric and marine conditions, ndërsa 7075 Alumini has fair to poor corrosion resistance and often requires a protective coating or anodizing for use in corrosive environments.
  3. Saldueshmëria:
    • 6061-T6 Alumini is highly weldable, making it suitable for structures requiring frequent welding. 7075 Alumini is difficult to weld and can suffer from cracking and brittleness after welding.
  4. Përpunueshmëria:
    • 6061-T6 Alumini is known for its good machinability, which is better than that of 7075 Alumini, although 7075 still offers acceptable machinability for most applications.
  5. Dendësia:
    • 7075 Alumini is slightly denser (2.81 g/cm³) than 6061-T6 Alumini (2.70 g/cm³), which can affect weight-sensitive applications.
  6. Përçueshmëria termike:
    • 6061-T6 Alumini has better thermal conductivity (167 W/m·K) compared to 7075 Alumini (130 W/m·K), making it preferable for heat-exchange applications.
