High Strength Aluminum Sheet FAQ

What is high-strength 5000 series aluminum sheet (DCE51) used for in 3C electronics?

High-strength aluminum sheet for electronics is used in smartphone support plates, laptop structural components, precision-stamped brackets, and other lightweight 3C parts. Suitable material conditions are selected according to the required strength, thickness, and forming process.

How does this material compare with conventional 5052 aluminum sheet?

DCE51 is a high-magnesium 5000 series alloy developed for high-strength electronic structural applications, while 5052 is commonly selected for general sheet metal fabrication and corrosion-resistant components. DCE51-H38 has a typical tensile strength of 390 MPa, although material comparisons should account for temper, thickness, and forming requirements.

Which tempers are suitable for precision stamping and bending?

O temper offers higher elongation for more demanding deformation, while H34 and H36 provide intermediate strength and forming capability. H38 and H18 offer higher-strength options where forming requirements are more controlled. The appropriate temper depends on part geometry, sheet thickness, bend radius, and tooling.

Can high-strength 5000 series aluminum sheet be anodized?

Anodizing may be considered for high-strength 5000 series aluminum components, but the final appearance depends on alloy composition, surface condition, and finishing parameters. For high-magnesium DCE51, black anodizing and other decorative finishes should be evaluated through sample trials before production.

Can Chalco supply aluminum sheet with mechanical properties comparable to GM55?

Yes. Chalco supplies DCE51 high-strength 5000 series aluminum sheet for projects evaluating GM55-comparable strength and forming requirements. DCE51 offers documented tensile and elongation properties across multiple tempers, allowing customers to assess its suitability against specific GM55 requirements. Final matching depends on thickness, temper, mechanical specifications, and forming conditions.

What specifications and quality documents are required for an RFQ?

Please provide the required alloy or target mechanical properties, temper, thickness, width, length, quantity, application, and any drawings or technical standards. Chalco can coordinate applicable material test certificates (MTC), certificates of conformity (CoC), and additional inspection requirements according to the agreed order specifications.
