Constantan® Pellets from Goodfellow are made from an alloy of copper and nickel that exhibits high electrical resistivity and low temperature coefficient of resistance. The high resistivity and low TCR make Constantan® well-suited for precision resistors and strain gauges that provide stable performance across a wide temperature range. As part of Goodfellow's expansive range of metal pellets, these Constantan® Pellets can be used for a variety of research, prototyping, and small-scale manufacturing applications. Their uniform size and consistent composition simplify experimental procedures and processes.
