Which is not true about high copper amalgam alloys______________?
Correct answer: A. Low tensile and compressive strength
- A. Low tensile and compressive strength
- B. Low Hg: Alloy ratio
- C. High tensile strength
- D. Low creep
Explanation
High-copper amalgams have higher tensile and compressive strength and lower creep because they eliminate or greatly reduce the weak gamma-2 phase. Therefore, low tensile and compressive strength is not true of them.
