Silicon carbide (SiC) abrasive: typical grinding applications For which materials is silicon carbide abrasive chiefly used in grinding operations? Choose the most appropriate option.

Difficulty: Easy

Cemented carbide only
Ceramic only
Cast iron only
All of these

Correct Answer: All of these

Explanation:

Concept/ApproachSilicon carbide (SiC) wheels are sharp and hard but relatively brittle; they are well suited for grinding hard, brittle, and short-chipping materials.

Applications

Cemented carbides (green SiC)
Ceramics (alumina, porcelain, etc.)
Cast iron (gray/white) and nonferrous metals

Final AnswerAll of these
