BERYLLIUM COPPER ALLOY
172 (UNS C17200) per
ASTM B 194
Properties of BERYLLIUM COPPER:
Chemical composition: Cu 98.1%, Be 1.9%
Temper as stamped: TD01
Properties after heat treatment (TH01):
Hardness: 36-43 Rockwell C
Mechanical Life: 100 Cycles Min.
Density: .298 lbs/in3
Electrical Conductivity: 22% IACS*
Resistance: 10 miliohms Max
Operating Temperature: -55°C/+125°C
Melting point: 980°C/865°C (liquidus/solidus)
Stress Relaxation†: 96% of stress remains after
1,000 hours @ 100 °C ; 70% of stress remains after
1,000 hours @ 200 °C
*International Annealed Copper Standard, i.e. as a % of pure copper.
†Since BeCu loses its spring properties over time at high temperatures; it is rated for continuous use up to 150°C. For
applications up to 300°C, Mill-Max offers many contacts in Beryllium Nickel. Contact Tech Support for more info.
