Corrosion Resistance： Why Aluminum Extrusion Products Thrive in Harsh Environments

Aluminum extrusion products excel where others falter, thanks to their natural corrosion resistance. At Southwest Aluminium (Kunshan) Co., Ltd, we’ve supplied corrosion-defying bars and tubes since 2012, serving industries like marine and electronics. Why is this trait so valuable?

Aluminum forms a protective oxide layer upon exposure to air, shielding it from rust and degradation. Unlike steel, our extruded 6063 or 7075 alloys resist saltwater, humidity, and chemicals, making them perfect for offshore platforms or smartphone casings. Extrusion enhances this by creating seamless tubes with no welds—weak points where corrosion often starts.

Our 8,000-ton extrusion presses craft profiles that endure, from curtain wall frames in coastal cities to aerospace components facing high-altitude moisture. Distributors rely on our ISO 9001 processes for consistent quality, while machining factories in Australia value our EN 755-compliant tubes for long-lasting parts. Optional anodizing boosts resistance further, adding durability and aesthetics.

Sustainability benefits too—corrosion-resistant extrusions reduce maintenance, extending product lifespans. With a 70,000-ton capacity and 24-hour quotes, we ensure stable supply for global clients. In a world of harsh conditions, Southwest Aluminium(Kunshan)’s extrusion products stand strong, proving resilience is built-in.
