ALLOY 390 MATERIAL & ALLOY 390E (UNS C17460) FOR DESIGN FLEXIBILITY
Alloy 390 copper beryllium alloy UNS C17460 offers the high strength of Alloy 25 (C17200) combined with the electrical conductivity of Alloy 3 or Alloy 174 (C17410 and C17510). Alloy 390E provides greater formability, but retains the strength and high conductivity of Alloy 390 material.
The combination of these properties allows engineers greater design flexibility when using these alloys for small, form factor signal and power interconnects used in harsh environments.
