III. Table of Common Selection Mistakes and Avoidance
Summarize the high-frequency mistakes in alloy grade selection, clarify the hazards and correct practices, help you avoid selection pitfalls, and reduce trial-and-error costs and product loss.
|
Common Selection Mistakes
|
Hazards of Mistakes
|
Correct Selection Practices
|
|
Blindly choosing high-strength alloys (such as 5052) for thin and precision parts
|
High stamping difficulty, easy cracking, increased loss and mold wear
|
Choose 1050/1060 pure aluminum series for thin and precision parts, no need to pursue high strength
|
|
Using 1060/3003 series alloys for pharmaceutical packaging
|
Does not meet pharmaceutical standards, has potential safety hazards and cannot be compliant
|
Must choose 8011, 8079 series for pharmaceutical/food packaging to ensure cleanliness and non-toxicity
|
|
Using pure aluminum series alloys for outdoor/auto parts
|
Insufficient strength, poor corrosion resistance, short product service life
|
Prioritize 5052, 5754 aluminum-magnesium alloys for outdoor and auto parts
|
|
Unified use of 1060 series for all scenarios
|
Cannot adapt to high-strength and ultra-thin scenarios, resulting in unqualified products
|
Match alloy types according to scenarios, do not blindly use universally
|
Conclusion: Choose the Right Alloy Grade for More Efficient and Worry-Free Stamping
The core selection logic for aluminum disc stamping is “matching alloy characteristics with scenarios” — pure aluminum series for general precision scenarios, aluminum-manganese alloy for medium-strength kitchenware scenarios, aluminum-magnesium alloy for high-strength outdoor/automotive scenarios, and aluminum-iron-silicon alloy for clean packaging scenarios.
