Which of the following statement is true regarding lathe cut low Copper silver alloy ?
Correct answer: C. Has tensile strength both at 15 minutes and 7 days is comparable to high copper, unicompositional alloys
- A. Requires least amount of mercury
- B. Achieves high compressive strength at 1 hr.
- C. Has tensile strength both at 15 minutes and 7 days is comparable to high copper, unicompositional alloys
- D. Has lower cree value
Explanation
Lathe-cut low-copper alloys generally require more mercury and develop lower early compressive strength than high-copper alloys, but their tensile strength at 15 minutes and 7 days can be comparable to high-copper unicompositional alloys. The other choices describe high-copper or spherical-alloy advantages rather than this alloy.
