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.
Typical Thickness Specifications
Range: 0.8 mm - 1.6 mm
This thickness range allows the material to meet crash performance, dent resistance, and formability requirements.
Sedan doors: Typically 0.9 - 1.2 mm
SUV/truck doors: May go up to 1.4 - 1.5 mm for increased rigidity
Common Tempers and Applications
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
- Prioritize 5182-O for complex EV door geometries
- Implement O/H24 hybrid solutions for premium vehicles
- 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
Manufacturing Capabilities
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 built up on the basis of outstanding management and complete quality control system under our rich experiences and have obtained many quality management certificates including ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, IATF 16949:2016, AS9100D, and approvals from ABS, DNV, LR, NK, KR National Classification Society.
3) We take social responsibility and regard environment protection as a main task for long-term development. Our facility features pulse-type bag dedust system from NEDERMAN Germany, with emission indexes of main exhaust substances and particles lower than national criteria.
