C19720 (ASTM B465) Alloy Data Specifications
Olin Brass Alloy C19720 is a dispersion strengthened, high conductivity copper alloy with mechanical and physical properties identical to Olin Brass C19700. C19720 was developed by modifying the chemistry of C197 in order to produce an alloy with improved reliability at elevated temperatures. C197 performs well up to 115°C, however, C19720 will maintain at least 70% of its initial stress after exposure to 125°C for 3000 hours and 150°C for 1000 hours. C19720 is an ideal fit for active contact applications in automotive power distribution where high current-carrying capability and good strength are required.
