Are aluminum outdoor benches prone to crevice corrosion in joints?
Aluminum outdoor benches are popular for their lightweight, durability, and resistance to rust. However, crevice corrosion can still occur in joints where moisture and debris accumulate. Unlike steel, aluminum forms a protective oxide layer, but in tight gaps, this layer may break down, leading to localized corrosion. To minimize risks, choose high-quality aluminum alloys (e.g., 6061-T6), ensure proper drainage in design, and apply protective coatings. Regular cleaning and inspections also help extend the bench’s lifespan. While not as prone as other metals, proactive maintenance is key to preventing joint corrosion in aluminum benches.
