BRUSH 60 ^® - A Competitive Advantage in Material Choice 

As connector design focuses on smaller, lighter products, smaller electronic footprints and lower package profiles become imperative. In addition, the increased power density required by today’s electronic packaging also results in greater power consumption. Under these conditions, signal integrity and thermal management issues become critical. 

Brush 60^® is a new, high conductivity copper beryllium strip alloy that is specifically engineered to meet today’s stringent electrical and mechanical connector requirements. Brush 60^® provides a material solution for those designers dealing with the issues of contact reliability and end-of-life performance. Elevated temperatures from increased power requirements can result in stress relaxation, a decline in contact normal force as a result of exposure to elevated temperature for a prolonged period of time. This degradation of contact force leads to an increase in contact resistance, greater signal distortion, higher impedance and signal propagation delay – all unacceptable conditions for optimized contact performance. Brush 60^® exhibits outstanding stress relaxation characteristics, and is therefore able to retain a higher normal force over the life of the connector. 

Brush 60^®, a mill hardened alloy, uses “lean” metallurgy and advanced processing techniques to satisfy these performance requirements while meeting the cost targets of the most demanding design. Contact us today to obtain a sample!
