Utilizing Lean Six Sigma methodology, Materion Brush Performance Alloys has made process breakthroughs that make it possible to produce an alloy that has both high strength and high conductivity. Our Alloy 390® combines the best attributes of two separate families of commercial copper beryllium alloys - the strength of the "high strength" alloy C17200 with the conductivity of "high conductivity" alloys C17410 and C17510. In addition to the combination of high strength and conductivity, Alloy 390® has excellent stress relaxation resistance at elevated temperatures. In applications where durability is important (burn-in and test sockets, board to board connectors, power connectors, relays, etc.), the excellent fatigue strength of Alloy 390® extends the product life, providing better utility, that translates into cost savings.

Potential uses of copper-nickel-beryllium Alloy 390® include computer burn-in and test sockets (BiTS), production sockets, power connectors, switch, relay, automotive power applications, as well as other hand held and portable electronic contact applications.
