- Check Standards: Ensure the plate meets industry standards like ASTM B209.
- Request Material Certification: Verify alloy composition and mechanical properties.
Comparing Different Alloys
| Property | 6061 | 7075 | 1050 |
|---|---|---|---|
| Strength | Moderate | High | Low |
| Corrosion Resistance | Good | Fair | Excellent |
| Weldability | Excellent | Poor | Good |
This table helps you understand which alloy suits your needs better.
Common Mistakes and How to Avoid Them
⚠️ ⚠注意：
- Choosing the wrong alloy for high-stress environments can lead to failure.
- Ignoring surface finish requirements may affect aesthetics and corrosion resistance.
- Overlooking industry standards could result in non-compliance.
Real-Life Case
Once, I ordered metric aluminum plates without verifying alloy specifications. The plates failed under load because they weren’t suitable for structural use. Always double-check alloy details!
Practical Steps to Work with Metric Aluminum Plate
Here’s a simple 5-step process for cutting and shaping your aluminum plates:
- Measure Accurately: Use calipers for precise dimensions.
- Mark Cutting Lines: Use a permanent marker and straightedge.
- Select Appropriate Tools: Use a fine-tooth saw or CNC machine.
- Cut Carefully: Apply consistent pressure and coolant if necessary.
- Finish Edges: Use a deburring tool for smooth edges.
Tips for Better Results
- Always wear safety gear.
- Use lubricants to reduce tool wear.
- Test cut on scrap material first.
