Effect of re-using nickel-chromium alloy on its ultimate tensile strength, yield strength and modulus of elasticity.

In order to bring down the cost of the castings used in fixed partial denture prosthesis, a study was conducted by reusing the nickel chromium alloy without adding any new material. We studied the effect on the ultimate tensile strength, yield strength and modulus of elasticity after reusing the nickel-chromium alloys. Results showed degenerative changes in the properties evaluated after recasting. These changes were statistically significant, suggesting that it can not be reused.
