BERYLLIUM COPPER ALLOYS
Brush Wellman produces two classes of beryllium copper alloys. The high strength beryllium copper alloys, which have good electrical and thermal conductivity, are used in applications such as springs, electronic connectors, bearings, molds and corrosion resistant hardware. The high conductivity beryllium copper alloys, possessing moderate strength, are the material of choice in current carrying springs, thermal control devices, welding electrodes, and power connectors.

All beryllium copper alloys are readily machinable using conventional processes and the guidelines provided in this brochure.

Both the high strength and the high conductivity Brush Wellman beryllium copper alloys are available in several wrought forms (strip, rod,
wire, bar, tube, plate), as cast billet, and as casting ingot.

For further information on beryllium copper alloy forms, compositions, specifications, properties, and manufacturing parameters, consult the Brush Wellman publications: Guide to Beryllium Copper, for wrought forms, and Beryllium Copper Casting

and Master Alloys, for cast forms. Additional literature and assistance in alloy selection or problem solving is also available to you from Brush Wellman’s Customer Technical Service Department at 800-321-2076, (In Ohio)
