Creep value of which of the following is the highest ?
Correct answer: A. Low copper amalgam alloy
- A. Low copper amalgam alloy
- B. Admix alloy
- C. Single composition alloys
- D. Creep value of all the above mentioned alloys is same
Explanation
Low-copper amalgams have the highest creep because they retain more of the weak gamma-2 tin-mercury phase. Admixed and single-composition high-copper alloys reduce or eliminate this phase and therefore show less creep.
