Arrange the following materials in order of their increasing die life:...
Increasing Die Life of Materials
Die life refers to the amount of time a die can be used before it needs to be replaced. The die life of a material depends on its strength, hardness, and wear resistance.
Given materials: brass, cast iron, zinc and aluminium
The correct order of increasing die life is:
c) cast iron, brass, aluminium and zinc
Explanation:
Cast iron has the highest die life among the given materials because of its high strength, hardness, and wear resistance. It can withstand high pressures and temperatures, making it ideal for use in dies.
Brass has a lower die life compared to cast iron because it is less strong and less wear-resistant. It can be used for low to medium pressure applications.
Aluminium has a lower die life than brass because it is even less strong and less wear-resistant than brass. It is suitable for low-pressure applications only.
Zinc has the lowest die life among the given materials because it is the weakest and least wear-resistant. It is used only for low-pressure applications.
Therefore, the correct order of increasing die life is cast iron, brass, aluminium and zinc.
