Why grade selection matters
Aluminum alloys vary widely in properties. A wrong choice can cause cracking, poor corrosion resistance, or extra cost.
Key factors
- Required strength and load
- Service environment and corrosion resistance
- Castability and machinability
- Weldability and coatability
Common grades
| Group | |
|---|---|
| Casting (3xx.x) | Die casting |
| Wrought (6xxx) | Profiles and structures |
Exact grade and standard are confirmed after reviewing your technical requirement.
