Question:-
Consider the following statements:
Assertion (A) : Aluminium alloys are cast in hot chamber die casting machine
Reason (R): Aluminium alloys require high melting when compared to zinc alloys
Option (A)
Both A and R are individually true and R is the correct explanation of A
Option (B)
Both A and R are individually true but R is not the correct explanation A
Option(C)
A is true but R is false
Option(D)
A is false but R is true
Correct Option:
(D)
Question Solution:
In hot chamber die casting machine low melting point material are used and aluminium alloy having high melting point. The melting point of Aluminium and zinc are 66°C and 422°C respectively. So cold chamber die casting is used for Aluminium alloys
