Abstract

In this paper we examine a measurement method for characterizing the dc conductivity of metal alloys commonly-used in hand weapons. From accurate measurements of the voltage and current across a cylindrical metal sample, we calculate the metal's dc conductivity. Equations for the dc conductivity are derived from first principles, including a detailed uncertainty analysis. In a measurement comparison with a National Institute of Standards and Technology Standard Reference Materila (SRM) for conductivity, we verified the performance of our measurement system. Using this system, we measured the dc conductivity results of ten metal alloys over the temperature range of 15 to 40 C.
