Nickel exhibits a negative gauge factor due to its unique electronic properties, which result in a decrease in electrical resistance when subjected to tensile strain. This characteristic significantly impacts the performance of strain gauges, as it can lead to inaccurate measurements under stress. Understanding the implications of using Nickel in strain gauges is crucial for applications requiring precise strain measurement, particularly in compliance with ASTM standards.
