The Correct Option is A
Solution and Explanation
Step 1: Understanding Babbitt metal.
Babbitt metal is a type of bearing metal, and it is an alloy of antimony, tin, and copper. It is used in high-speed machinery for bearings due to its ability to reduce friction.
Step 2: Analyzing the options.
(A) Babbitt metal: Correct — Babbitt metal is an alloy of antimony, tin, and copper.
(B) Spiegeleisen: Spiegeleisen is an alloy of iron with high carbon and is used for making steel, not an alloy of antimony, tin, and copper.
(C) Duralumin: Duralumin is an alloy of aluminum, copper, and other elements but does not contain antimony or tin.
(D) Stainless steel: Stainless steel is an alloy of iron, chromium, and sometimes nickel, not an alloy of antimony, tin, and copper.
Step 3: Conclusion.
The correct answer is (A) Babbitt metal.
