Aluminum alloy grade comparison is essential for global sourcing, engineering design, and international trade. Different countries use different aluminum designation systems such as AA (USA), EN (Europe), JIS (Japan), GB/T (China), and ISO, which can easily cause confusion during procurement.
This aluminum alloy cross-reference guide helps buyers, engineers, and importers quickly identify equivalent aluminum grades, reduce specification risks, and ensure compliance with international standards such as ASTM, EN, and ISO.
As a professional Aluminum Alloy Supplier, Manufacturer, and Exporter, we specialize in supplying a full range of aluminum alloys, including 1050, 1060, 1070, 1100, 3003, 3004, 3105, 5005, 5052, 5083, 5086, 5754, 6061, 6063, 6082, and high-strength 7050 and 7075 aluminum alloys, in the form of aluminum sheets, plates, coils,foils, strips, extrusions, bars, and customized processed products.
All aluminum materials are produced and inspected in accordance with international standards such as ASTM, EN, and ISO, with Mill Test Certificates (EN 10204 3.1) available upon request. We support multiple tempers including O, H14, H24, H32, H116, T4, T5, T6, T651, and T73, and offer strict chemical composition control, mechanical property verification, and third-party inspection for export projects.
Whether you are sourcing aluminum for marine structures, automotive components, architectural systems, pressure vessels, aerospace tooling, or general industrial fabrication, our experienced technical and export teams can provide alloy selection support, standard equivalency guidance (ASTM vs EN vs JIS), competitive pricing, stable lead times, and global shipping solutions.

How Buyers & Engineers Use This Table
H tempers → strain-hardened (non-heat-treatable alloys: 1xxx / 3xxx / 5xxx)
T tempers → heat-treated (6xxx / 7xxx series)
Marine projects prefer H116 / H321
Structural & CNC machining prefer T6 / T651
Always confirm thickness-specific limits per ASTM B209 / EN 485
Standard Systems Explanation (For Buyers)
ASTM / AA (USA) – American Aluminum Association designation
EN – European Norm (EN AW series)
JIS – Japanese Industrial Standards
GB/T – China National Standard
ISO – International Standardization
Buyer Notes (Important)
Chemical composition and temper may vary slightly between standards
Always confirm ASTM B209 / EN 485 / JIS H4000 compliance before ordering
For export projects, EN ↔ ASTM matching is critical for customs and inspection
