• 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.

Beillesztés & Hasadás korrózió

• 5052-H32 shows minimal pitting in 5 % NaCl salt-spray tests beyond 500 óra 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.

Stressz-korrózió-repedés (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.
