Yes, aluminum can oxidize over time, especially in coastal/saltwater environments. In normal outdoor use, the oxidation is usually cosmetic and slow, but galvanic corrosion between aluminum and stainless can occur in harsh wet/salty conditions. For maximum long-term durability outdoors or near the ocean, many users upgrade to 316 stainless steel crimp sleeves/fittings instead of aluminum. if this answer does not resolve the current issue, please contact us again for assistance.

The swage/crimp sleeves included in this kit are typically aluminum alloy, while the cable itself is 304 stainless steel. Aluminum sleeves are commonly used with stainless wire rope for light-to-medium duty applications like deck railings and garden trellises.
