Excellent mechanical properties. _Excellent conductivity.

Discover our range of Beryllium-reinforced Copper alloys.

  • Components durability and reliability
  • High performance for harsh environment applications
  • Be-free and Lead-free alternatives to match REACH and RoHS regulations

Due to their microstructure, Beryllium-reinforced Copper alloys offer excellent mechanical properties, even at low alloying levels, which allows them to also excel in conductivity properties.
However, the use of Beryllium is increasingly restricted because of health and environment concerns. Therefore Lebronze alloys also offers Be-free alternatives, for example Hardiall CuNiSn products for mechanical and toughness performance, and CuNiSi products for high thermal conductivity or high temperature resistance.
