Assertion (A): Aluminium alloys are cast in hot ch... moreamber die ca...
Explanation:
Aluminium alloys have a higher melting point compared to zinc alloys, which is why they are cast in hot chamber die casting machines. The hot chamber die casting machine is suitable for materials with lower melting points like zinc alloys. Since aluminium alloys require higher melting temperatures, they are typically cast in cold chamber die casting machines.
Reasoning:
- Aluminium alloys have a higher melting point than zinc alloys
- Hot chamber die casting machines are designed for materials with lower melting points like zinc alloys
- Cold chamber die casting machines are used for materials with higher melting points like aluminium alloys
Therefore, the assertion that aluminium alloys are cast in hot chamber die casting machines is false, while the reason stating that aluminium alloys require high melting temperatures compared to zinc alloys is true.
