Iron Copper Alloy C19720
UNS C19720
Description
C19720 is a dispersion strengthened, high conductivity copper alloy with mechanical and physical properties identical to C19700. C19720 maintains at least 70% of its initial stress after exposure to 125 ℃ for 3000hours and 150 ℃ for 1000 hours. Due to its superior electrical conductivity, strength and resistance to stress relaxation, C19720 reduces the size and weight of spring-equipped electrical and electronic components and suppresses the increase in heat generation associated with high currents.
