Product Description

Strip or Plate Type Copper-beryllium used for Contact Springs / Switches / Relays

Copper-beryllium alloys are mainly based on copper with a beryllium addition. High strength beryllium copper alloys contain 0.4-2% of beryllium with about 0.3 to 2.7% of other alloying elements such as nickel, cobalt, iron or Lead. The high mechanical strength is achieved by precipitation hardening or age hardening.
Beryllium Copper is a copper alloy with the optimum combination of mechanical and physical properties such as tensile strength, fatigue strength, performance under elevated temperatures, electrical conductivity, bending formability and corrosion resistance. Beryllium Copper is widely used as contact springs in various applications like connectors, switches, relays, etc.

Features  
1. High thermal conductivity
2. High corrosion resistance, especially suitable for polyoxyethylene (PVC) products mold.
3. High hardness, wear resistance and toughness, as inserts used with mould steel and aluminium can make the mold play a highly efficient, prolong the service life.
4. Polishing performance is good, can achieve high mirror surface precision and complicated shape design.
5. Good tackiness resistance, easy to welding with other metal, easy to machining, there is no need additional heat treatment.
