1.	Which property of aluminum it the most preferred element?(a) good conductivity(b) highly malleable, highly ductile(c) most abundant element(d) good corrosion resistantI have been asked this question in unit test.My question comes from High Conductivity Materials in portion Electrical Engineering Materials of Design of Electrical Machines
Answer» Correct ANSWER is (c) most abundant element The best I can explain: All the other elements AMONG Silver, Copper, Gold have the other 3 properties ALONG with Aluminum. But all the above MENTIONED materials are not HIGHLY abundant, which is also an important factor.
