*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 other materials. Contact Tech Support for more info.

ADDITIONAL NOTES & SPECIFICATIONS
In the interest of improved design, quality and performance , Mill-Max reserves the right to make changes in its specifications without prior
notice. Specifications and tolerances are provided wherever possible. The tolerance on dimensions of critical to function features is typically
held tighter than the stated standard tolerances, such as press-fits, holes and lengths affecting the coplanarity of SMT products. Due to the
