Contact Strips Made of Copper Beryllium
Application
Due to their outstanding materiai and electrical characteristics, copper beryllium fingers of different shapes and dimensions are used in the following industries: Broadcasting, telecommunication, industriai contrai, measuring and instrumentation, aerospace technology, nuclear physics and data processing. Contact fingers and rings made of copper beryllium are used at all radio and microwave frequencies, for instance as contacts to tubes and tuning components as well as for shielding.
Materiai Properties
The copper beryllium (CuBe2) used for our products is a quality tested quench hardening spring materiai. lt is noteworthy for its yield point, tensile strength and elasticity, good electrical conductivity, high fatigue strength as well as its resistance to abrasion and corrosion. The good thermal conductivity coupled with hardness eliminates sparking. The raw materiai is non-magnetic and has an excellent temperature performance.
