Heat treatment of a nickel-chromium base metal alloy produced changes (percent elongation, ultimate tensile strength, modulus of elasticity, yield strength, and hardness) that simulated properties of various types of noble metal alloys. Further research is indicated to determine if the properties of a base metal alloy can be altered by heat treatment or other means to enable its use for a wide variety of fixed dental restorations.
