Question

From the list below, select four situations in which casting is the preferred fabrication technique. (1) For alloys having low ductilities (2) When it is the most economical fabrication technique (3) When it is needed to join a large variety of metals and alloys (4) For large pieces and/or complicated shapes (5) For economical producing of parts that require very close dimensional tolerances (e.g. bushing and gears) (6) When mechanical strength is not an important consideration

Answer 1

Answer:

(1) , (2) , (4) ,(6).

Explanation:

Use of casting process:

1.When the size of the mold is more or we can say that when the size of casting is more.

2.When the mechanical strength of the casting product is not important.

3.When the required ductility of the product is not to high .Generally casting product is more brittle with high strength.

4.Generally cost of casting product is not too high or we can say that casting product is economically.

Therefore the following options are correct -

(1) , (2) , (4) ,(6).
