Sandvik Cuprothal Thermocouple
Categories:	Metal; Nonferrous Metal; Copper Alloy
Material Notes:	CUPROTHAL is the negative leg of the following types of thermocouples and compensating cables: E, J, L, T and KCB (VX). The alloy can be used at temperatures down to 20 K where its Seebeck coefficient is about 8 mV / °C. Thermocouple type E has the highest emf output of any common thermocouple and is for this reason used in thermal generators (thermopiles). CUPROTHAL type T is matched with electrolytic copper (ASTM standard B3). Thermocouple type T is both used in laboratory and industrial applications. CUPROTHAL type KNCB (VNX) is matched with electrolytic copper when used in compensating cables for thermocouples type K. Information provided by Sandvik
