Are aluminum outdoor ottomans prone to stress corrosion in chloride environments?

Aluminum outdoor ottomans are popular for their lightweight, modern aesthetic, and resistance to rust. However, in chloride-rich environments—such as coastal areas or places with de-icing salts—aluminum can be susceptible to stress corrosion cracking (SCC). This occurs when tensile stress, combined with corrosive chloride exposure, leads to micro-cracks and eventual material failure.

While aluminum alloys like 6061 and 6063 offer good corrosion resistance, prolonged exposure to chlorides without proper maintenance can accelerate degradation. Powder-coated or anodized finishes provide additional protection, but regular cleaning and avoiding harsh chemicals are essential for longevity.

For outdoor use in chloride-prone areas, choosing high-grade aluminum or alternative materials like stainless steel may be advisable. Proper design and stress distribution also minimize SCC risks, ensuring your outdoor ottomans remain durable and stylish for years.
