Q1: Hot extrusion of aluminium is done in the temperature range of __________ °C.A 550-600
B 450-500
C 350-400
D 250-300
ANS:C - 350-400 While the temperature range of 350-400°C (662-752°F) may be suitable for some specific applications of hot extrusion, it is generally not commonly used for extruding aluminum. At temperatures below 450°C (842°F), aluminum may not be sufficiently softened for efficient extrusion, and the extrusion process may become more challenging due to increased resistance to deformation. Additionally, aluminum's low melting point of approximately 660°C (1220°F) means that temperatures below 450°C are relatively close to its solidus temperature, making it less suitable for typical hot extrusion processes. Therefore, while temperatures in the range of 350-400°C could potentially be used for specific applications or with specialized alloys, they are not commonly utilized for general hot extrusion of aluminum. It's important to note that the optimal temperature range for hot extrusion of aluminum is typically considered to be around 450-500°C (842-932°F), as mentioned earlier. |
