Correct answer: B. Cermets
- A. Copper-lead alloys
- B. Cermets
- C. Bronzes
- D. Babbitts
Explanation
Copper-lead alloys, Babbitts, and bronzes are established bearing materials because they combine load capacity with suitable friction and wear properties. Cermets are mainly hard, wear-resistant composite materials for cutting tools and are not conventional bearing materials in this context.
