Brush Wellman Beryllium Nickel Strip - Alloy 390

 

Subcategory: Copper Alloy; Nickel Alloy; Nonferrous Metal; Beryllium Alloy

Key Words: burn in and test socket, bits

Material Notes:
Description: Alloy 390 was specifically designed for high power applications, providing a unique combination of high strength and high conductivity. Increasing power requirements are driving the need for lower conductor resistance to reduce joule heating. Higher thermal conductivity is critical to thermal management. Higher power requirements are creating harsh environments and higher operating temperatures. Alloy 390 provides excellent stress relaxation resistance at elevated temperatures increasing electrical contact reliability. Alloy 390 has good formability making it possible to create small form factor electrical contacts used in computer, telecommunication, automotive and appliance applications. Alloy 390 is available in strip form ranging from 0.003" to 0.010" thick.
