Aluminum Alloy 5083 Aluminum Alloy Plate for Hydraulic Equipment Enclosures (3–5 mm | Custom Width | Anodized Anti-Rust Layer)

Introduction

The 5083 hard-anodized aluminum plate (3–5 mm thickness, 1000–2600 mm custom width, 25–40 μm Class-I hard anodizing + sealing) is the global heavy-industry standard for ultra-durable, zero-maintenance hydraulic power unit and valve enclosures.

• Alloy 5083-H116/H321: 4.5 % Mg → highest strength & corrosion resistance in 5xxx series, DNV-GL certified.

• Hard anodizing (hardness 400–500 HV): 2500 h salt-spray, permanent metallic finish, oil-resistant.

• Extra-wide + laser-flatness: ready for CNC machining, deep welding, and high-pressure environments.
  Result: enclosures that survive 40 years in offshore C5-M & hydraulic oil splash zones, reduce weight 70 %, and install 75 % faster than stainless steel.
