5000 Series High Strength Aluminum Alloy 5182 For Car Outer Door Panel

Aluminum 5182 H18 sheets belong to the 5000 series of aluminum alloys, which are primarily

alloyed with magnesium, offering a perfect balance of strength, corrosion resistance, and formability.

Common Tempers

O (Annealed):

Used when maximum formability is required (e.g. for deep-drawing operations).

Very soft, ideal for stretch forming.

H111:

Slightly strain-hardened; offers a balance of strength and formability.

Commonly used in stamped automotive body panels.

H32:

Moderately strain-hardened and partially annealed.

Provides higher yield strength and better dent resistance than O or H111.

Used when surface rigidity and stiffness are more critical.

Engineering Recommendations:

1) Prioritize 5182-O for complex EV door geometries

2) Implement O/H24 hybrid solutions for premium vehicles

3) Adopt tailored blank technology for mass production cost optimization

Performance Advantages

♦ Excellent formability

Ideal for deep drawing and complex contour shaping required for door panels.

♦ High corrosion resistance

Magnesium in 5182 provides strong protection against atmospheric and road salt corrosion.

♦ Moderate to high strength

Sufficient for structural integrity without adding excess weight.

♦ Good dent resistance

Especially in H32 temper, provides better surface rigidity and impact resistance.

Company Advantages

1) Full sets of imported vertical intelligent storage and logistic management system, and finishing

lines which fulfill all the requirements on various kinds of Aluminium plate,sheet and strip products.

2) We have has built up on the basis of outstanding management and complete quality control system

under its rich experiences and has got many kinds of quality management certificates such as ISO

9001:2015, ISO14001:2015,ISO45001:2018,IATF16949:2016,AS9100D, and has passed ABS, DNV,

LR,NK,KR etc.proof from National Classification Society.

3) We take social responsibility and regards environment protection as main task for long-term develop

- ment.It is featured with pulse-type bag dedust system from NEDERMAN Germany,which emission

index of main exhaust stuff and particles are lower than national criteria.
