Corrosion Resistant 5052 H32 Automobile Aluminum Plate For Car Door

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.

Our Company

♦ We have implemented standardized processes to enhance work efficiency, reduce confusion,

minimize errors, and boost overall productivity.

♦ A comfortable and well-lit work environment, combined with a reasonably arranged office layout,

fosters a positive work attitude, healthy interpersonal relationships, and sustained team growth

motivation, while enhancing team cohesion and a sense of belonging.

Our factory own the world advanced equipments, include:

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.
