3.2. Types of Aluminum

Try these first

1. 1.

   What is pure aluminum defined as in terms of percentage?

   Hint

   Think about the purity level needed for applications.

2. 2.

   Name one application of the 3xxx series aluminum alloy.

   Hint

   Consider common uses in lightweight products.

3. 3.

   What percentage of aluminum defines pure aluminum?

   • 50%
   • 75%
   • 99%

   Hint

   Consider the level of purity for structural use.

4. 4.

   True or False: The 2xxx series aluminum is more resistant to corrosion than the 5xxx series.

   • True
   • False

   Hint

   Reflect on the properties of aluminum alloys.

5. 5.

   Based on the properties of the 7xxx series alloy, describe a scenario where it would provide a critical advantage over 2xxx and 5xxx series alloys.

   Hint

   Consider high-stress environments and the balance of weight to strength ratio.

6. 6.

   As a civil engineer, if tasked with designing a coastal building, differentiate the choices between using 5xxx and a 6061 alloy. Which would be better and why?

   Hint

   Think about environmental exposure's long-term effects on materials.
