Beryllium Copper alloy strip B25 used for contacts spring

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.

The copper-beryllium alloys processed by Tankii offer a wide combination of mechanical and electrical properties which is unique for copper alloys. The mechanical strength achieved after heat treatment ranks highest amongst all the copper alloy materials and is combined with a high electrical conductivity which outperforms that of bronzes.

Our alloys combine a range of properties particularly suited to meet the exacting requirements of many applications in the automotive, electronic, aeronautical, Oil&Gas, watch, electro-chemical industries, etc. Beryllium Copper is widely used in those fields as contact springs in various applications like connectors, switches, relays, etc. Tankii offers a variety of Beryllium Copper alloys in several tempers to cover different applications.
