Try these first

1. 1.

   What makes aluminum easy to machine?

   Hint

   Think about the physical properties of aluminum.

2. 2.

   Name one welding technique used for aluminum.

   Hint

   These techniques are commonly associated with aluminum.

3. 3.

   What is a common welding technique for aluminum?

   • TIG
   • SMAW
   • Plasma

   Hint

   Think of the welding method that requires a non-consumable electrode.

4. 4.

   True or False: Aluminum is difficult to machine because of its high melting point.

   • True
   • False

   Hint

   Consider aluminum's properties compared to other metals.

5. 5.

   Evaluate the impact of using a high-silicon alloy in casting processes for aluminum. What advantages do high-silicon alloys present compared to low-silicon alloys?

   Hint

   Consider how alloy compositions affect the material properties.

6. 6.

   Design a case study where you demonstrate the pros and cons of using aluminum for large-scale construction. What considerations must be made?

   Hint

   Analyze both sides of the aluminum application in your case study.
