Brush 60® Strip TH03 (C17460) – High-Performance Copper Beryllium Alloy

Materion Performance Alloys Brush 60 is a high performance, lower priced copper beryllium alloy offering cost effective solutions for many applications. Available in mill hardened tempers.

As components are reduced in size and signal requirements become more stringent, the selection of materials is of increasing importance. Total cost solutions demand materials which provide design flexibility, ease of manufacturing, and life cycle reliability. Brush 60 (C17460) was performance engineered with these criteria in mind. Key benefits include:

Greater contact force and conductivity to improve signal transfer

Superior high temperature durability

Freedom to form intricate parts at high strength levels

Complete recyclability
