Alloys having more than 80% copper are generally more______________________?
Correct answer: B. Corrosion resistant
- A. Abrasion resistant
- B. Corrosion resistant
- C. Prone to season cracking
- D. Machinable
Explanation
Copper-rich alloys are generally resistant to atmospheric and many aqueous corrosive environments because copper forms a protective surface film. Season cracking is associated particularly with brass, while machinability depends on the specific alloy composition.
