Density: .298 lbs/in3 Electrical Conductivity: 22% IACS* Resistance: 10 miliohms Max Operating Temperature: -55C/+125C Melting point: 980C/865C (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 150C. For applications up to 300C, Mill-Max offers many contacts in Beryllium Nickel.

A partial anneal down to 6010 RB is recommended for 90 bends, a full anneal down to 3515 RB is recommended for pins or terminals that are swaged (riveted) to a circuit board or crimped to a wire. RoHS-2 directive 2011/65/EU, exemption 6c allows up to 4% lead as an alloy agent in copper. *International Annealed Copper Standard, i.e. as a % of pure copper.
