Aluminium.
Aluminium alloys sourced around alloy series, temper, product form, joining route, surface and structural requirement.
Identify grade and condition together.
Designations are preliminary cross-references for enquiry routing. The governing product specification, exact grade designation, condition or temper, dimensions and application requirements must be stated together.
| Family / common name | UNS or alloy designation | EN / international reference | Selection context |
|---|---|---|---|
| Commercial purity | 1050 / 1100 | 1xxx | Formability, conductivity and general sheet work |
| High-strength Al-Cu | 2024 | 2xxx | Aerospace and fatigue-critical structures |
| General-purpose Al-Mn | 3003 | 3xxx | Formed sheet and heat-transfer components |
| Al-Mg | 5052 | 5xxx | Sheet fabrication and corrosion resistance |
| Marine Al-Mg | 5083 | 5xxx | Marine plate and welded structures |
| Al-Mg | 5754 | 5xxx | Transport and formed sheet |
| Al-Mg-Si | 6061 | 6xxx | Plate, bar, tube and extrusion |
| Al-Mg-Si | 6082 | 6xxx | Structural extrusion and machined parts |
| High-strength Al-Zn | 7075 | 7xxx | Aerospace and highly loaded parts |
Designation relationships require verification against the governing specification. Technical data is provided for preliminary sourcing guidance. The applicable customer specification, drawing, purchase order and latest standard revision govern each requirement.

Technical data is provided for preliminary sourcing guidance. The applicable customer specification, drawing, purchase order and latest standard revision govern each requirement.
Grade alone is not enough.
Condition, heat treatment, product form, dimensions, surface, corrosion testing, mechanical properties, NDE, traceability and documentation can materially change the supply route.
Bhansali reviews the requirement and coordinates supplier qualification, QA/QC, independent laboratory verification and third-party inspection where required.
