Aluminum Alloy Database
This database is a starting point for comparing common wrought aluminum alloy families and identifying the information to confirm before placing an order. Alloy designation alone is not a complete material specification: product form, temper, thickness, applicable standard and required properties all matter.
Specification note: The descriptions below are general selection guidance, not a certificate of conformity or a guarantee that a particular grade, temper or size is currently available. Confirm the governing ASTM, EN, GB or other purchase specification with the supplier.
Browse aluminum alloy series
| Series | Main alloying system | General characteristics | Common selection context |
|---|---|---|---|
| 1xxx | Commercially pure aluminum | High electrical/thermal conductivity and corrosion resistance; strength is generally lower than heat-treatable structural alloys. | Electrical, chemical, heat-transfer and general forming applications. |
| 2xxx | Aluminum-copper | Many grades are heat-treatable and designed for high strength; corrosion protection and joining requirements need attention. | Strength-oriented engineering and aerospace-related applications where specification permits. |
| 3xxx | Aluminum-manganese | Generally non-heat-treatable, with useful formability and corrosion resistance. | General sheet, heat exchangers, building and cookware-related applications. |
| 5xxx | Aluminum-magnesium | Generally non-heat-treatable; good corrosion resistance and useful strength, especially in marine and transport contexts. | Marine structures, vehicle components, tanks and fabricated plate/sheet. |
| 6xxx | Aluminum-magnesium-silicon | Heat-treatable alloys combining strength, corrosion resistance and extrudability or machinability depending on grade and temper. | Structural profiles, machined parts, transport and general engineering. |
| 7xxx | Aluminum-zinc | High-strength heat-treatable alloys; corrosion and stress-corrosion behavior must be evaluated for the selected grade and temper. | High-strength components where the design specification supports their use. |
Common grades to research
| Grade | Series | Typical points to evaluate |
|---|---|---|
| 1050 / 1060 | 1xxx | Purity, conductivity, forming requirements, surface finish and thickness tolerance. |
| 1100 | 1xxx | Formability, corrosion environment, joining and required strength. |
| 3003 | 3xxx | Formability, corrosion resistance, temper and application-specific strength. |
| 5052 | 5xxx | Temper, forming radius, corrosion exposure, welding and thickness. |
| 5083 / 5086 | 5xxx | Marine or structural specification, temper, plate thickness, weld procedure and inspection requirements. |
| 5754 | 5xxx | Formability, corrosion exposure, surface requirements and automotive/industrial specification. |
| 6061 | 6xxx | Temper, machining, weldability, strength requirement and corrosion environment. |
| 6063 | 6xxx | Extrusion geometry, surface finish, anodizing requirement and temper. |
| 6082 | 6xxx | Structural design requirements, temper, section/product form and applicable standard. |
| 7075 | 7xxx | Strength, fatigue, corrosion protection, stress-corrosion considerations and specification. |
What to confirm before selecting an alloy
- Product form: sheet, plate, coil, strip, foil, circle, bar or extrusion.
- Exact alloy and temper, including any suffix or special condition.
- Thickness, width, length, dimensional tolerances and flatness requirements.
- Mechanical properties and test direction where specified.
- Surface finish, coating, anodizing or protective-film requirements.
- Applicable material standard, inspection documents and traceability requirements.
- Fabrication route: forming, welding, machining, bending or heat treatment.
