  • Good points

  1. Very good in bend formability and high electrical conductivity for connectors. This unique combination of properties lends the alloy to uses in a vast array of applications including CPU sockets, automotive and electrical connectors and various springs.

  2. Particularly suitable for replacement of Beryllium Copper, with eco-friendliness and cost competitiveness for its chemical composition.

  3. Excellent bend formability though its strength is higher than C7025.

  4. Very good stress relaxation and heat resistance properties at elevated temperature as well as C7025.

  5. No heat treatment required for hardening.
