5. Reżistenza għall-korrużjoni & Imġieba tal-wiċċ

Reżistenza ġenerali għall-korrużjoni

• 5052 is often considered one of the most corrosion-resistant aluminum alloys in marine and industrial environments due to its high Mg content and Cr additions.
  It withstands seawater, sprej tal-melħ, and many chemical exposures with minimal attack.
• 6061 has good general corrosion resistance but is inferior to 5052 in chloride-rich or highly acidic/basic conditions.
  Anodizing improves 6061’s durability, but in raw form, 6061 is more prone to pitting in salt spray tests.

Pitting & Korrużjoni tax-xquq

• 5052-H32 shows minimal pitting in 5 % NaCl salt-spray tests beyond 500 sigħat if surfaces are properly finished.
  The stable passive film (Al₂o₃ + Mg-rich oxides) repels chloride ions effectively.
• 6061-T6 begins showing small pits under similar conditions after ≈ 200 hours unless a hard-coat anodize or conversion coating is applied.
  Crevice corrosion can initiate under tight joints or gasketed areas.

Qsim tal-korrużjoni tal-istress (SCC)

• 5052 has virtually no SCC susceptibility even under sustained tensile loads in a chloride environment.
• 6061-T6 is moderately susceptible to SCC if subjected to tensile stresses above 75 % of yield in chloride media.
  Overaging to T4 jew T5 temper reduces SCC risk but also lowers peak strength.

Surface Treatment Recommendations

• 6061 can be welded by GMAW/TIG as well, Iżda heat-affected zones (Haz) in T6 will soften to ≈ 50 % of base strength (≈ 145 Rendiment tal-MPA).
  Biex terġa 'tinkiseb is-saħħa, a T4 → T6 re-aging cycle is often required: weld in T4, then solution treat and artificially age.
  Common fillers are 4043 (Al-si) for crack resistance or 5356 (Al-mg) for higher weld strength; each affects HAZ differently.

Makkinabilità

• 5052 has a machinability rating of approximately 40 % (relative to the 2011 aluminum baseline).
  It machines with moderate speeds (150–200 m / i) using carbide tooling.

  Surface finishes of RA 1.6-3.2 µm are achievable in 2–4 mm depth-of-cut operations.
• 6061 punteġġi 60–70 % makkinabilità. It accepts higher cutting speeds (200–300 m / i) and maintains excellent surface finish (RA 0.8-1.6 µm).
  Carbide tools with positive rake angles and flood coolant maximize tool life. Swarf tends to break into small chips, facilitating safe evacuation.

Tifforma & Liwi

• 5052-H32 can be bent to a radius as small as 1× its thickness without cracking, making it ideal for complex stamped or drawn parts (E.g., Tankijiet tal-fjuwil, marine panels).
