Aluminum Stampings Characteristics
There are many reasons why aluminum might fit the needs of your deep drawn part. Aluminum deep drawn stampings are commonly used in the power storage, beverage container, battery, and pharmaceutical industries, and for decorative packaging. Another high use for aluminum is for heat reduction or as a heat sink.
Some of the key advantages of using aluminum for your deep drawn part include:
- Aluminum is light weight, with a specific gravity that is roughly 1/3% that of low carbon steel.
- Aluminum has an excellent strength to weight ratio
- Aluminum is non-magnetic
- Aluminum will not rust, making it ideal for parts that need to be rust resistant
- Aluminum is heat treatable
- Aluminum can be anodized to create a decorative surface finish, and to provide corrosion resistance.
Aluminum Forming Benefits and Challenges
In addition to the many positive characteristics of deep drawn aluminum stampings, there are additional benefits and challenges that an aluminum stamping manufacturer needs to be aware of. These include:
- Lower tonnage is required, when compared to most other common metals used in deep drawn stampings
- Deep drawing aluminum results in high tool wear, something a manufacturer needs to take into account with tight tolerance needs.
- Aluminum has good dimensional capability (+/- .001” or .04mm)
- Aluminum has low spring back characteristics
- Aluminum is very formable
- Aluminum has very low work hardening characteristics
- It is possible to deep draw aluminum stampings with variable wall thickness.
The characteristics, benefits and challenges listed above should be considered from the perspective of a stamping company. To assure you match the right grade for your application please consult a metallurgist or conduct your own research before choosing a grade of steel.
