Aluminum Alloy 5083 Aluminum Plate Hydraulic Equipment Box (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, 30–50 μm Class-I hard anodizing + sealing) is the heavy-industry gold standard for ultra-rugged, zero-maintenance hydraulic power packs, valve stands and control boxes.

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

• Hard anodizing (hardness 450–550 HV): 3000 h salt-spray, oil-proof, permanent metallic finish.

• Extra-wide + precision leveling: ready for CNC machining, deep welding and extreme pressure environments.
  Result: boxes that survive 40 years of offshore splash-zone + hydraulic oil exposure, cut weight 70 %, and are fabricated 75 % faster than stainless steel.
