COPPER ALLOY TROLLEY WIRE AND METHOD FOR MANUFACTURING COPPER ALLOY TROLLEY WIRE |
摘要 |
A copper alloy trolley wire includes: 0.12 mass% to 0.40 mass% of Co; 0.040 mass% to 0.16 mass% of P; 0.005 mass% to 0.70 mass% of Sn; and the balance including Cu and unavoidable impurities, wherein precipitates have an average grain size of equal to or greater than 10 nm, and the number of precipitates having a grain size of equal to or greater than 5 nm is 90% or greater of the total number of observed precipitates, and a heat resistance HR defined by HR=TS 1 /TS 0 ×100 in which TS 0 is an initial tensile strength and TS 1 is a tensile strength after holding the copper alloy trolley wire at 400°C for 2 hours, is equal to or greater than 90%. |
