Corrosion Resistant 5052 H32 Automobile Aluminum Plate 5052 Alloy Sheet
5052 aluminum is a versatile premium-grade material suitable for a wide range of applications,
magnesium and chromium — the two most prevalent alloying element significantly increase the
aluminum’s strength, durability, and corrosion resistance.
5052 aluminum alloy is widely used in automotive door manufacturing. It is typically employed
in non-load bearing or low-stress components, serving as a lightweight alternative to traditional
steel doors.

For oversize sheet, we use Flat Rack Container for shipping
1) We use suitable securing material, such as wooden blocks, steel straps, and ratchet
tie-downs to firmly fix the aluminum plates to the flat rack.
2) To prevent possible exposure to seawater or rain, we cover the entire cargo with
waterproof tarps.
3) We make sure these sheets are loaded with a low and evenly distributed center of
gravity to avoid tilting during the transportation.
Door Structure and Key Applications of 5052
An automotive door typically consists of:
• Outer panel (visible exterior)
• Inner panel (structural skeleton)
• Reinforcement beam (for crash protection)
• Window frame and trim components
Our Factory's samples
5052 aluminum is primarily used in the following areas:
(1) Door Inner Panel
Function: Provides structural support and houses interior components (e.g.,handles,speakers,wiring).
(2) Door Outer Panel
Function: Forms the exterior aesthetic and aerodynamic surface.
(3) Door Reinforcement Beam
Function: Absorbs impact energy during side collisions.
Advantages and Challenges of 5052 in Doors
✅ Advantages
Weight Reduction: 30–50% lighter than steel, improving fuel efficiency (ICE vehicles) or battery
range (EVs).
Corrosion Resistance: Ideal for humid or salt-exposed environments.
Design Flexibility: Easily formed into complex geometries.
Recyclability: Fully recyclable, aligning with sustainability goals.
