Question

What are the advantages and disadvantages of alloys? (Meals)

Answer 1

Advantages of alloys
1.High strength-to-weight ratios
2.Low density, so greater bulk for same weight means they can be used in a greater thickness than denser materials, and thus are less prone to local buckling; this applies to magnesium alloys even more than aluminum alloys
3.Available in many standard forms - sheet, plate, tube, bar, extrusions aluminum alloys are easy to work after simple heat treatment
3.Can be super-plastically formed (certain aluminum alloys only)

Disadvantages of aluminum and magnesium alloys
1. Prone to corrosion, so need protective finishes, particularly magnesium alloys
2.Many alloys have limited strength, especially at elevated temperatures magnesium alloys have low strength (but high strength-to-weight ratio)
3.No fatigue limit

Answer 2
