Aluminum Material Selection
Aluminum Stock Forms & Tempers for CNC Machining
Aluminum material selection requires more than an alloy designation: temper, supplied form and applicable specification also matter.
- Process
- Review the proposed stock form before machining
- Материалы
- Confirm alloy, temper, product form and specification
- Количество
- State required quantities and traceability needs
- Inspection
- Agree material documentation for the supplied lot
Product Overview
A complete aluminum material specification may include the alloy designation, temper, product form, dimensions and applicable material standard.
Each element serves a different purpose.
The alloy designation defines composition limits. The temper describes the material condition. Product form and section size influence which property requirements apply.
Matching an alloy and temper name alone does not always establish that two forms of stock are interchangeable.
Key Features
- Aluminum machining projects may begin with plate, bar, extrusion or other stock forms.
- Plate is often considered for mounting structures, housings and components requiring broad machined faces.
- Round bar can be suitable for turned parts such as sleeves, rings and shafts.
- Extruded profiles may be useful where the design can take advantage of a consistent cross-section.
- Suitability depends on the supplied specification, available dimensions and final part requirements.
Manufacturing Considerations
- If an extruded bar is proposed in place of a specified plate, compare the relevant mechanical property requirements for each product form.
- Section thickness and the direction associated with material testing can also matter.
- The proposed material must meet the applicable design and procurement requirements, not merely share a similar commercial designation.
- Any substitution requiring design approval should be agreed before production.
Quality Control & Inspection
- Where required, material certification should reference the approved specification and relevant supplied lot.
- The required documentation is confirmed for the project.
Specifications to Confirm
| Supplied form and size | State the product form and actual stock dimensions. |
|---|---|
| Material properties | Confirm applicable requirements and test direction for that supplied form. |
| Traceability | Specify any required certificate and lot linkage. |
Assembly Considerations
Permitted substitutions
Identify which stock forms may be substituted and who must approve the change.
Discuss Aluminum Material Options
Send your drawing and required alloy, temper, product form and specification. If an alternative form is acceptable, identify the permitted substitutions or the approval process so manufacturing options can be reviewed.
