C50715

Standard

JIS DIN EN ASTM/UNS/CDA GB/T
KLF5 / / C50715 /

Merit

This alloy belongs to work hardening alloys, with a heat resistance temperature about 100 ℃ higher than phosphor bronze, and a conductivity about 40% to 50% higher than brass and phosphor bronze. It has excellent high-temperature creep resistance and excellent stamping formability. It has better stress relaxation resistance and corrosion cracking resistance than phosphor bronze. Good conductivity can replace tin phosphorus bronze in many situations.
